FIXME: Do we need to generate dependencies in partial symtabs?
|
|
|
|
(Perhaps we don't need to).
|
1991-10-24 19:28:54 +08:00
|
|
|
|
|
|
|
FIXME: Resolve minor differences between what information we put in the
|
|
|
|
partial symbol table and what dbxread puts in. For example, we don't yet
|
|
|
|
put enum constants there. And dbxread seems to invent a lot of typedefs
|
|
|
|
we never see. Use the new printpsym command to see the partial symbol table
|
|
|
|
contents.
|
|
|
|
|
|
|
|
FIXME: Figure out a better way to tell gdb about the name of the function
|
|
|
|
contain the user's entry point (I.E. main())
|
|
|
|
|
|
|
|
FIXME: See other FIXME's and "ifdef 0" scattered throughout the code for
|
|
|
|
other things to work on, if you get bored. :-)

the information for a single DIE, the one currently being processed.
|
|
|

of the current DIE, which are specifically unordered within the DIE,

each DIE is scanned and an instance of the "struct dieinfo"
|
|

structure is initialized.
|
|
|
|
|
|
|
|
Initialization is done in two levels. The first, done by basicdieinfo(),
|
|
|
|
just initializes those fields that are vital to deciding whether or not
|
|
|
|
to use this DIE, how to skip past it, etc. The second, done by the

function completedieinfo(), fills in the rest of the information.
|
|
|
|
|
|
|
|
Attributes which have block forms are not interpreted at the time
|
|
|
|
the DIE is scanned, instead we just save pointers to the start
|
|
|
|
of their value fields.
|
|
|
|
|
|
|
|
Some fields have a flag <name>_p that is set when the value of the
|
|
|
|
field is valid (I.E. we found a matching attribute in the DIE). Since
|
|
|
|
we may want to test for the presence of some attributes in the DIE,

such as AT_low_pc, without restricting the values of the field,
|

we need someway to note that we found such an attribute.

other DIES for the type information. Thus we need to associate the offset
|
|
|
|
of a DIE for a user defined type with a pointer to the type information.
|
|
|
|
|
|
|
|
Originally this was done using a simple but expensive algorithm, with an
|
|
|
|
array of unsorted structures, each containing an offset/type-pointer pair.
|
|
|
|
This array was scanned linearly each time a lookup was done. The result
|
|
|
|
was that gdb was spending over half it's startup time munging through this
|
|
|
|
array of pointers looking for a structure that had the right offset member.
|
|
|
|
|
|
|
|
The second attempt used the same array of structures, but the array was
|
|
|
|
sorted using qsort each time a new offset/type was recorded, and a binary
|
|
|
|
search was used to find the type pointer for a given DIE offset. This was
|
|
|
|
even slower, due to the overhead of sorting the array each time a new
|
|
|
|
offset/type pair was entered.
|
|
|
|
|
|
|
|
The third attempt uses a fixed size array of type pointers, indexed by a
|
|
|
|
value derived from the DIE offset. Since the minimum DIE size is 4 bytes,
|
|
|
|
we can divide any DIE offset by 4 to obtain a unique index into this fixed
|
|
|
|
size array. Since each element is a 4 byte pointer, it takes exactly as
|
|
|
|
much memory to hold this array as to hold the DWARF info for a given
|
1992-12-04 04:28:16 +08:00
|
|
|
compilation unit. But it gets freed as soon as we are done with it.
|
|
|
|
This has worked well in practice, as a reasonable tradeoff between memory
|
|
|
|
consumption and speed, without having to resort to much more complicated
|
|
|
|
algorithms. */

Create and use macros for iterating on symtabs, psymtabs, msymbols.
* minsyms.c (iterate_over_msymbols): Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols): Remove prototype
* coffread.c (coff_symfile_read): iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types): Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols): explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs): Remove, clunky and slow.
* objfiles.h: Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile): Remove dummy args and results. Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command): iterate_over_* => ALL_*. Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list): Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1): Protect '/' tests from short filenames.
(cplus_mangled_symbol): Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols): Remove poor hack.
(relocate_minimal_symbol): Move inline to vmap_symtab.

iterate_over_msymbols with ALL_MSYMBOLS.
Misc cleanup prior to release.
* dwarfread.c (dwarf_build_psymtabs): Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs): Remove, unused.
* mipsread.c: Add prototypes for all static functions.

DESCRIPTION
|
|
|
|
|
|
|
|
DWARF version 1 doesn't supply any fundamental type information,
|
|
|
|
so gdb has to construct such types. It has a fixed number of
|
|
|
|
fundamental types that it knows how to construct, which is the
|
|
|
|
union of all types that it knows how to construct for all languages
|
|
|
|
that it knows about. These are enumerated in gdbtypes.h.
|
|
|
|
|
|
|
|
As an example, assume we find a DIE that references a DWARF
|
|
|
|
fundamental type of FT_integer. We first look in the ftypes
|
|
|
|
array to see if we already have such a type, indexed by the
|
|
|
|
gdb internal value of FT_INTEGER. If so, we simply return a
|
|
|
|
pointer to that type. If not, then we ask an appropriate
|
|
|
|
language dependent routine to create a type FT_INTEGER, using
|
|
|
|
defaults reasonable for the current target machine, and install
|
|
|
|
that type in ftypes for future reference.
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
|
|
|
|
Pointer to a fundamental type.

remember what the language was. We use this at various times
|
|
|
|
when processing DIE's for a given compilation unit.

DESCRIPTION
|
|
|
|
|
|
|
|
This function is called upon to build partial symtabs from files
|
|
|
|
containing DIE's (Dwarf Information Entries) and DWARF line numbers.
|
|
|
|
|
1992-10-15 21:40:40 +08:00
|
|
|
It is passed a bfd* containing the DIES
|
1991-10-24 19:28:54 +08:00
|
|
|
and line number information, the corresponding filename for that
|
|
|
|
file, a base address for relocating the symbols, a flag indicating
|
|
|
|
whether or not this debugging information is from a "main symbol
|
|
|
|
table" rather than a shared library or dynamically linked file,
|
|
|
|
and file offset/size pairs for the DIE information and line number
|
|
|
|
information.
|
|
|
|
|

|
|
RETURNS
|
|
|

Create and use macros for iterating on symtabs, psymtabs, msymbols.
* minsyms.c (iterate_over_msymbols): Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols): Remove prototype
* coffread.c (coff_symfile_read): iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types): Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols): explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs): Remove, clunky and slow.
* objfiles.h: Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile): Remove dummy args and results. Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command): iterate_over_* => ALL_*. Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list): Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1): Protect '/' tests from short filenames.
(cplus_mangled_symbol): Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols): Remove poor hack.
(relocate_minimal_symbol): Move inline to vmap_symtab.
(vmap_symtab): Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.
Misc cleanup prior to release.
* dwarfread.c (dwarf_build_psymtabs): Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs): Remove, unused.
* mipsread.c: Add prototypes for all static functions.
* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove 2nd
unused copy!
* buildsym.c (define_symbol): Handle global register variables
(from Pierre Willard). Complain if register numbers are too large.

read_structure_scope -- process all dies within struct or union

SYNOPSIS
|
|
|
|
|
|
|
|
static void read_structure_scope (struct dieinfo *dip,
|
1991-12-05 07:40:07 +08:00

|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Called when we find the DIE that starts a structure or union
|
|
|
|
scope (definition) to process all dies that define the members
|
|
|
|
of the structure or union. DIP is a pointer to the die info
|
|
|
|
struct for the DIE that names the structure or union.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
Note that we need to call struct_type regardless of whether or not
|
1991-12-07 03:51:01 +08:00
|
|
|
the DIE has an at_name attribute, since it might be an anonymous
|
|
|
|
structure or union. This gets the type entered into our set of
|
|
|
|
user defined types.
|
|
|
|
|
|
|
|
However, if the structure is incomplete (an opaque struct/union)
|
|
|
|
then suppress creating a symbol table entry for it since gdb only
|
|
|
|
wants to find the one with the complete definition. Note that if
|
|
|
|
it is complete, we just call new_symbol, which does it's own
|
|
|
|
checking about whether the struct/union is anonymous or not (and
|
|
|
|
suppresses creating a symbol table entry itself).

|
As the last step in decoding the array subscript information for an

|
|
|
passed a pointer to this last part of the subscript information and

|
must return the appropriate type. If the type attribute is not
|
|
|
|
recognized, just warn about the problem and return type int.

DESCRIPTION
|
|
|
|
|
|
|
|
The array subscripts and the data type of the elements of an
|
|
|
|
array are described by a list of data items, stored as a block
|
|
|
|
of contiguous bytes. There is a data item describing each array
|
|
|
|
dimension, and a final data item describing the element type.
|
|
|
|
The data items are ordered the same as their appearance in the
|
|
|
|
source (I.E. leftmost dimension first, next to leftmost second,
|
|
|
|
etc).
|
|
|
|
|
1992-12-15 10:52:11 +08:00
|
|
|
The data items describing each array dimension consist of four
|
|
|
|
parts: (1) a format specifier, (2) type type of the subscript
|
|
|
|
index, (3) a description of the low bound of the array dimension,
|
|
|
|
and (4) a description of the high bound of the array dimension.
|
|
|
|
|
|
|
|
The last data item is the description of the type of each of
|
|
|
|
the array elements.
|
|
|
|
|
1991-10-24 19:28:54 +08:00
|
|
|
We are passed a pointer to the start of the block of bytes
|
1992-12-15 10:52:11 +08:00
|
|
|
containing the remaining data items, and a pointer to the first
|
|
|
|
byte past the data. This function recursively decodes the
|
|
|
|
remaining data items and returns a type.
|
|
|
|
|
|
|
|
If we somehow fail to decode some data, we complain about it
|
|
|
|
and return a type "array of int".

by the AT&T and GNU C compilers.

use it for that...

DESCRIPTION
|
|
|
|
|
|
|
|
Given a pointer to a die information structure for the die which
|
|
|
|
starts an enumeration, process all the dies that define the members
|
|
|
|
of the enumeration and return a type pointer for the enumeration.

|
|
|
|
1991-12-06 10:22:10 +08:00
|
|
|
At the same time, for each member of the enumeration, create a
|
|
|
|
symbol for it with namespace VAR_NAMESPACE and class LOC_CONST,
|
|
|
|
and give it the type of the enumeration itself.

NOTES

|
1991-12-05 13:09:20 +08:00
|
|
|
Note that the DWARF specification explicitly mandates that enum
|
|
|
|
constants occur in reverse order from the source program order,
|
|
|
|
for "consistency" and because this ordering is easier for many
|
1992-02-22 09:46:16 +08:00
|
|
|
compilers to generate. (Draft 6, sec 3.8.5, Enumeration type
|

|
Entries). Because gdb wants to see the enum members in program
|
|
|
|
source order, we have to ensure that the order gets reversed while

we are processing them.

|

DESCRIPTION
|
|
|
|
|
|
|
|
Process all dies within a given function scope. We are passed
|
|
|
|
a die information structure pointer DIP for the die which
|
|
|
|
starts the function scope, and pointers into the raw die data
|
|
|
|
that define the dies within the function scope.
|
|
|
|
|
|
|
|
For now, we ignore lexical block scopes within the function.
|
|
|
|
The problem is that AT&T cc does not define a DWARF lexical
|
|
|
|
block scope for the function itself, while gcc defines a
|
|
|
|
lexical block scope for the function. We need to think about
|
|
|
|
how to handle this difference, or if it is even a problem.

DESCRIPTION
|
|
|
|
|
|
|
|
Process all dies within a given file scope. We are passed a
|
|
|
|
pointer to the die information structure for the die which
|
|
|
|
starts the file scope, and pointers into the raw die data which
|
|
|
|
mark the range of dies within the file scope.
|
|
|
|
|
|
|
|
When the partial symbol table is built, the file offset for the line
|
|
|
|
number table for each compilation unit is saved in the partial symbol
|
|
|
|
table entry for that compilation unit. As the symbols for each
|
|
|
|
compilation unit are read, the line number table is read into memory
|
|
|
|
and the variable lnbase is set to point to it. Thus all we have to
|
|
|
|
do is use lnbase to access the line number table for the current
|
|
|
|
compilation unit.

decode_line_numbers -- decode a line number table fragment
|
|
|
|
|
|
|
|
SYNOPSIS
|
|
|
|
|
|
|
|
static void decode_line_numbers (char *tblscan, char *tblend,
|
|
|
|
long length, long base, long line, long pc)
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Translate the DWARF line number information to gdb form.
|
|
|
|
|
|
|
|
The ".line" section contains one or more line number tables, one for
|
|
|
|
each ".line" section from the objects that were linked.
|
|
|
|
|
|
|
|
The AT_stmt_list attribute for each TAG_source_file entry in the
|
|
|
|
".debug" section contains the offset into the ".line" section for the
|
|
|
|
start of the table for that file.
|
|
|
|
|
|
|
|
The table itself has the following structure:
|
|
|
|
|
|
|
|
<table length><base address><source statement entry>
|
|
|
|
4 bytes 4 bytes 10 bytes
|
|
|
|
|
|
|
|
The table length is the total size of the table, including the 4 bytes
|
|
|
|
for the length information.
|
|
|
|
|
|
|
|
The base address is the address of the first instruction generated
|
|
|
|
for the source file.
|
|
|
|
|
|
|
|
Each source statement entry has the following structure:
|
|
|
|
|
|
|
|
<line number><statement position><address delta>
|
|
|
|
4 bytes 2 bytes 4 bytes
|
|
|
|
|
|
|
|
The line number is relative to the start of the file, starting with
|
|
|
|
line 1.
|
|
|
|
|
|
|
|
The statement position either -1 (0xFFFF) or the number of characters
|
|
|
|
from the beginning of the line to the beginning of the statement.
|
|
|
|
|
|
|
|
The address delta is the difference between the base address and
|
|
|
|
the address of the first instruction for the statement.
|
|
|
|
|
|
|
|
Note that we must copy the bytes from the packed table to our local
|
|
|
|
variables before attempting to use them, to avoid alignment problems
|
|
|
|
on some machines, particularly RISC processors.
|
|
|
|
|
|
|
|
BUGS
|
|
|
|
|
|
|
|
Does gdb expect the line numbers to be sorted? They are now by
|
|
|
|
chance/luck, but are not required to be. (FIXME)
|
|
|
|
|
|
|
|
The line with number 0 is unused, gdb apparently can discover the
|
|
|
|
span of the last line some other way. How? (FIXME)

LOCAL FUNCTION

locval -- compute the value of a location attribute
|
|
|

|
|
|
|
SYNOPSIS
|
|
|
|
|
|
|
|
static int locval (char *loc)
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Given pointer to a string of bytes that define a location, compute
|
|
|
|
the location and return the value.
|
1995-07-20 13:52:42 +08:00
|
|
|
A location description containing no atoms indicates that the
|
|
|
|
object is optimized out. The global optimized_out flag is set for
|
|
|
|
those, the return value is meaningless.
|
1991-10-24 19:28:54 +08:00
|
|
|
|
|
|
|
When computing values involving the current value of the frame pointer,
|
|
|
|
the value zero is used, which results in a value relative to the frame
|
|
|
|
pointer, rather than the absolute value. This is what GDB wants
|
|
|
|
anyway.
|
|
|
|
|
|
|
|
When the result is a register number, the global isreg flag is set,
|
|
|
|
otherwise it is cleared. This is a kludge until we figure out a better
|
|
|
|
way to handle the problem. Gdb's design does not mesh well with the
|
|
|
|
DWARF notion of a location computing interpreter, which is a shame
|
|
|
|
because the flexibility goes unused.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
Note that stack[0] is unused except as a default error return.
|
|
|
|
Note that stack overflow is not yet handled.

add to a partial symbol table, finish filling in the die info
|
|
|
|
and then add a partial symbol table entry for it.

language for current compilation unit being processed.
* dwarfread.c (set_cu_language): New local function to decode
and record language for current compilation unit being processed.
* dwarfread.c (synthesize_typedef): Add local function to
synthesize a typedef for C++ classes, structs, unions, and
enumerations.
* dwarfread.c (read_structure_scope): Synthesize typedefs
for C++ classes, structs and unions.
* dwarfread.c (read_enumeration): Synthesize typedefs for
C++ enumerations.

to record language for current compilation unit.
* dwarfread.c (scan_partial_symbols): Call add_enum_psymbol here
for TAG_enumeration_types, rather than in add_partial_symbol.
* dwarfread.c (add_partial_symbol): Combine TAG_enumeration_type
case with class, struct, and union type cases, now that they are
the same. Remove tests for non-NULL name attributes, now done
by callers.
* gdbtypes.h (TYPE_CODE_CLASS): Add type for C++ classes, but
treat as alias for TYPE_CODE_STRUCT for now.

DESCRIPTION
|
|
|
|
|
|
|
|
Process the DIE's within a single compilation unit, looking for
|
|
|
|
interesting DIE's that contribute to the partial symbol table entry
|
1992-08-11 13:29:41 +08:00
|
|
|
for this compilation unit.

NOTES
|
|
|
|
|
1992-08-11 13:29:41 +08:00
|
|
|
There are some DIE's that may appear both at file scope and within
|
|
|
|
the scope of a function. We are only interested in the ones at file
|
|
|
|
scope, and the only way to tell them apart is to keep track of the
|
|
|
|
scope. For example, consider the test case:
|
|
|
|
|
|
|
|
static int i;
|
|
|
|
main () { int j; }
|
|
|
|
|
|
|
|
for which the relevant DWARF segment has the structure:
|
|
|
|
|
|
|
|
0x51:
|
|
|
|
0x23 global subrtn sibling 0x9b
|
|
|
|
name main
|
|
|
|
fund_type FT_integer
|
|
|
|
low_pc 0x800004cc
|
|
|
|
high_pc 0x800004d4
|
|
|
|
|
|
|
|
0x74:
|
|
|
|
0x23 local var sibling 0x97
|
|
|
|
name j
|
|
|
|
fund_type FT_integer
|
|
|
|
location OP_BASEREG 0xe
|
|
|
|
OP_CONST 0xfffffffc
|
|
|
|
OP_ADD
|
|
|
|
0x97:
|
|
|
|
0x4
|
|
|
|
|
|
|
|
0x9b:
|
|
|
|
0x1d local var sibling 0xb8
|
|
|
|
name i
|
|
|
|
fund_type FT_integer
|
|
|
|
location OP_ADDR 0x800025dc
|
|
|
|
|
|
|
|
0xb8:
|
|
|
|
0x4
|
|
|
|
|
|
|
|
We want to include the symbol 'i' in the partial symbol table, but
|
|
|
|
not the symbol 'j'. In essence, we want to skip all the dies within
|
|
|
|
the scope of a TAG_global_subroutine DIE.
|
|
|
|
|
1991-12-06 10:22:10 +08:00
|
|
|
Don't attempt to add anonymous structures or unions since they have
|
|
|
|
no name. Anonymous enumerations however are processed, because we
|
|
|
|
want to extract their member names (the check for a tag name is
|
|
|
|
done later).

|
|
|
|
1991-12-06 10:22:10 +08:00
|
|
|
Also, for variables and subroutines, check that this is the place
|
|
|
|
where the actual definition occurs, rather than just a reference
|
|
|
|
to an external.

LOCAL FUNCTION

scan_compilation_units -- build a psymtab entry for each compilation
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
This is the top level dwarf parsing routine for building partial
|
|
|
|
symbol tables.
|
|
|
|
|
|
|
|
It scans from the beginning of the DWARF table looking for the first
|
|
|
|
TAG_compile_unit DIE, and then follows the sibling chain to locate
|
|
|
|
each additional TAG_compile_unit DIE.
|
|
|
|
|
|
|
|
For each TAG_compile_unit DIE it creates a partial symtab structure,
|
|
|
|
calls a subordinate routine to collect all the compilation unit's
|
|
|
|
global DIE's, file scope DIEs, typedef DIEs, etc, and then links the
|
|
|
|
new partial symtab structure into the partial symbol table. It also
|
|
|
|
records the appropriate information in the partial symbol table entry
|
|
|
|
to allow the chunk of DIE's and line number table for this compilation
|
|
|
|
unit to be located and re-read later, to generate a complete symbol
|
|
|
|
table entry for the compilation unit.
|
|
|
|
|
|
|
|
Thus it effectively partitions up a chunk of DIE's for multiple
|
|
|
|
compilation units into smaller DIE chunks and line number tables,
|
|
|
|
and associates them with a partial symbol table entry.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
If any compilation unit has no line number table associated with
|
|
|
|
it for some reason (a missing at_stmt_list attribute, rather than
|
|
|
|
just one with a value of zero, which is valid) then we ensure that
|
|
|
|
the recorded file offset is zero so that the routine which later
|
|
|
|
reads line number table fragments knows that there is no fragment
|
|
|
|
to read.
|
|
|
|
|
|
|
|
RETURNS
|
|
|
|
|
|
|
|
Returns no value.

DESCRIPTION
|
|
|
|
|
|
|
|
Given a pointer to a DWARF information entry, figure out if we need
|
|
|
|
to make a symbol table entry for it, and if so, create a new entry
|
|
|
|
and return a pointer to it.

DESCRIPTION
|
|
|
|
|
|
|
|
Decode a block of data containing a modified user defined
|
|
|
|
type specification. TYPEDATA is a pointer to the block,
|
|
|
|
which consists of a two byte length, containing the size
|
|
|
|
of the rest of the block. At the end of the block is a
|
|
|
|
four byte value that gives a reference to a user defined type.
|
|
|
|
Everything in between are type modifiers.
|
|
|
|
|
|
|
|
We simply compute the number of modifiers and call the general
|
|
|
|
function decode_modified_type to do the actual work.

decode_modified_type -- decode modified user or fundamental type

SYNOPSIS
|
|
|
|
|
1992-06-15 22:26:57 +08:00
|
|
|
static struct type *decode_modified_type (char *modifiers,
|

unsigned short modcount, int mtype)
|
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Decode a modified type, either a modified fundamental type or
|
|
|
|
a modified user defined type. MODIFIERS is a pointer to the
|
|
|
|
block of bytes that define MODCOUNT modifiers. Immediately
|
|
|
|
following the last modifier is a short containing the fundamental
|
|
|
|
type or a long containing the reference to the user defined
|
|
|
|
type. Which one is determined by MTYPE, which is either
|
|
|
|
AT_mod_fund_type or AT_mod_u_d_type to indicate what modified
|
|
|
|
type we are generating.
|
|
|
|
|
|
|
|
We call ourself recursively to generate each modified type,`
|
|
|
|
until MODCOUNT reaches zero, at which point we have consumed
|
|
|
|
all the modifiers and generate either the fundamental type or
|
|
|
|
user defined type. When the recursion unwinds, each modifier
|
|
|
|
is applied in turn to generate the full modified type.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
If we find a modifier that we don't recognize, and it is not one
|
|
|
|
of those reserved for application specific use, then we issue a
|
|
|
|
warning and simply ignore the modifier.
|
|
|
|
|
|
|
|
BUGS
|
|
|
|
|
|
|
|
We currently ignore MOD_const and MOD_volatile. (FIXME)

decode_fund_type -- translate basic DWARF type to gdb base type
|

|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Given an integer that is one of the fundamental DWARF types,
|
|
|
|
translate it to one of the basic internal gdb types and return
|
|
|
|
a pointer to the appropriate gdb type (a "struct type *").
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
1992-12-15 10:52:11 +08:00
|
|
|
For robustness, if we are asked to translate a fundamental
|
|
|
|
type that we are unprepared to deal with, we return int so
|
|
|
|
callers can always depend upon a valid type being returned,
|
|
|
|
and so gdb may at least do something reasonable by default.
|
|
|
|
If the type is not in the range of those types defined as
|
|
|
|
application specific types, we also issue a warning.

basicdieinfo -- extract the minimal die info from raw die data

SYNOPSIS
|
|
|
|
|
1992-04-11 14:27:53 +08:00
|
|
|
void basicdieinfo (char *diep, struct dieinfo *dip,
|
|
|
|
struct objfile *objfile)
|
1991-10-24 19:28:54 +08:00
|
|
|
|
|
|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Given a pointer to raw DIE data, and a pointer to an instance of a
|
|
|
|
die info structure, this function extracts the basic information
|
|
|
|
from the DIE data required to continue processing this DIE, along
|
|
|
|
with some bookkeeping information about the DIE.
|
|
|
|
|
|
|
|
The information we absolutely must have includes the DIE tag,
|
|
|
|
and the DIE length. If we need the sibling reference, then we
|
|
|
|
will have to call completedieinfo() to process all the remaining
|
|
|
|
DIE information.
|
|
|
|
|
|
|
|
Note that since there is no guarantee that the data is properly
|
|
|
|
aligned in memory for the type of access required (indirection
|
1992-04-11 14:27:53 +08:00
|
|
|
through anything other than a char pointer), and there is no
|
|
|
|
guarantee that it is in the same byte order as the gdb host,
|
|
|
|
we call a function which deals with both alignment and byte
|
|
|
|
swapping issues. Possibly inefficient, but quite portable.
|
1991-10-24 19:28:54 +08:00
|
|
|
|
|
|
|
We also take care of some other basic things at this point, such
|
|
|
|
as ensuring that the instance of the die info structure starts
|
|
|
|
out completely zero'd and that curdie is initialized for use
|
|
|
|
in error reporting if we have a problem with the current die.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
All DIE's must have at least a valid length, thus the minimum
|
1992-04-14 12:09:00 +08:00
|
|
|
DIE size is SIZEOF_DIE_LENGTH. In order to have a valid tag, the
|
|
|
|
DIE size must be at least SIZEOF_DIE_TAG larger, otherwise they
|
1991-10-24 19:28:54 +08:00
|
|
|
are forced to be TAG_padding DIES.
|
|
|
|
|
1992-04-14 12:09:00 +08:00
|
|
|
Padding DIES must be at least SIZEOF_DIE_LENGTH in length, implying
|
|
|
|
that if a padding DIE is used for alignment and the amount needed is
|
|
|
|
less than SIZEOF_DIE_LENGTH, then the padding DIE has to be big
|
|
|
|
enough to align to the next alignment boundry.
|
1992-10-02 01:33:21 +08:00
|
|
|
|
|
|
|
We do some basic sanity checking here, such as verifying that the
|
|
|
|
length of the die would not cause it to overrun the recorded end of
|
|
|
|
the buffer holding the DIE info. If we find a DIE that is either
|
|
|
|
too small or too large, we force it's length to zero which should
|
|
|
|
cause the caller to take appropriate action.

|
|
|
aligned in memory for the type of access required (indirection
|
1992-04-11 14:27:53 +08:00
|
|
|
through anything other than a char pointer), and there is no
|
|
|
|
guarantee that it is in the same byte order as the gdb host,
|
|
|
|
we call a function which deals with both alignment and byte
|
|
|
|
swapping issues. Possibly inefficient, but quite portable.

Each time we are called, we increment the diecount variable, which

keeps an approximate count of the number of dies processed for
|

each compilation unit. This information is presented to the user

|
|

if the info_verbose flag is set.

SYNOPSIS
|
|
|
|
|
|
|
|
target_to_host (char *from, int nbytes, int signextend,
|
|
|
|
struct objfile *objfile)

|
|
DESCRIPTION
|
|
|
|
|
|
|
|
Given pointer to data in target format in FROM, a byte count for
|
|
|
|
the size of the data in NBYTES, a flag indicating whether or not
|
|
|
|
the data is signed in SIGNEXTEND, and a pointer to the current
|
|
|
|
objfile in OBJFILE, convert the data to host format and return
|
|
|
|
the converted value.
|
|
|
|
|
|
|
|
NOTES
|
|
|
|
|
|
|
|
FIXME: If we read data that is known to be signed, and expect to
|
|
|
|
use it as signed data, then we need to explicitly sign extend the
|
|
|
|
result until the bfd library is able to do this for us.
|
|
|
|
|
1995-03-03 14:26:25 +08:00
|
|
|
FIXME: Would a 32 bit target ever need an 8 byte result?

DESCRIPTION
|
|
|
|
|
|
|
|
Given a DWARF attribute in ATTR, compute the size of the first

piece of data associated with this attribute and return that
|
|
|
|
size.
|
|
|
|
|
|
|
|
Returns -1 for unrecognized attributes.
