d11261fc63 Fix symbol table file name on AIX 
When xlc -qfuncsect or gcc -ffunction-sections options is used in AIX,
each function csect is associated with each psymtab, so each psymtab
will have it's corresponding filename entries set.

If the pst filename isn't set then we will be seeing the below output
when we set a breakpoint.

(gdb) br main
Breakpoint 1 at 0x10000374: file  _start_ , line 18.

With the fix it will be.

(gdb) br main
Breakpoint 1 at 0x10000518: file test.c, line 24.

Attached patch resolve this issue and correct filename will be set.

	* xcoffread.c (read_xcoff_symtab): Make name of current file as
	pst->filename instead of _start_ in AIX.

a2e3e93f44 Fix two misleading indentation warnings 
Two small changes so everything builds with latest GCC and its
-Wmisleading-indentation.

In the aarch64-tdep.c case, the two misindented lines should actually be
part of the for loop.  It looks like the indentation is all done using
spaces in that file though...  I fixed it (changed for tabs + spaces) for
the lines I touched.

In the xcoffread.c case, we can simply remove the braces and fix the
indentation.

gdb/ChangeLog:

	* aarch64-tdep.c (aarch64_record_asimd_load_store): Add braces
	to for include additional lines.
	* xcoffread.c (scan_xcoff_symtab): Remove unnecessary braces.

224c3ddb89 Add casts to memory allocation related calls 
Most allocation functions (if not all) return a void* pointing to the
allocated memory.  In C++, we need to add an explicit cast when
assigning the result to a pointer to another type (which is the case
more often than not).

The content of this patch is taken from Pedro's branch, from commit
"(mostly) auto-generated patch to insert casts needed for C++".  I
validated that the changes make sense and manually reflowed the code to
make it respect the coding style.  I also found multiple places where I
could use XNEW/XNEWVEC/XRESIZEVEC/etc.

Thanks a lot to whoever did that automated script to insert casts, doing
it completely by hand would have taken a ridiculous amount of time.

Only files built on x86 with --enable-targets=all are modified.  This
means that all other -nat.c files are untouched and will have to be
dealt with later by using appropiate compilers.  Or maybe we can try to
build them with a regular g++ just to know where to add casts, I don't
know.

I built-tested this with --enable-targets=all and reg-tested.

Here's the changelog entry, which was not too bad to make despite the
size, thanks to David Malcom's script.  I fixed some bits by hand, but
there might be some wrong parts left (hopefully not).

be90335825 gdb: Remove casts of NULL during assignment. 
In the following code:

    struct symbol *wsym = (struct symbol *) NULL;

the cast of NULL is redundant, it adds noise, and is just one more thing
to change if the type of wsym ever changes.  There are a relatively
small number of places in gdb where the above code pattern is used.
Usually the cast is removed like this:

    struct symbol *wsym = NULL;

This commit updates all the places within the gdb/ directory where we
cast NULL during assignment, removing the cast.

8d7493201c Replace some xmalloc-family functions with XNEW-family ones 
This patch is part of the make-gdb-buildable-in-C++ effort.  The idea is
to change some calls to the xmalloc family of functions to calls to the
equivalents in the XNEW family.  This avoids adding an explicit cast, so
it keeps the code a bit more readable.  Some of them also map relatively
well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be
possible to do scripted replacements if needed.

I only changed calls that were obviously allocating memory for one or
multiple "objects".  Allocation of variable sizes (such as strings or
buffer handling) will be for later (and won't use XNEW).

  - xmalloc (sizeof (struct foo)) -> XNEW (struct foo)
  - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num)
  - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo)
  - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num)
  - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num)
  - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo)
  - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num)
  - alloca (sizeof (struct foo)) -> XALLOCA (struct foo)
  - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num)

Some instances of xmalloc followed by memset to zero the buffer were
replaced by XCNEW or XCNEWVEC.

I regtested on x86-64, Ubuntu 14.04, but the patch touches many
architecture-specific files.  For those I'll have to rely on the
buildbot or people complaining that I broke their gdb.

63e43d3aed DWARF: handle non-local references in nested functions 
GDB's current behavior when dealing with non-local references in the
context of nested fuctions is approximative:

  - code using valops.c:value_of_variable read the first available stack
    frame that holds the corresponding variable (whereas there can be
    multiple candidates for this);

  - code directly relying on read_var_value will instead read non-local
    variables in frames where they are not even defined.

This change adds the necessary context to symbol reads (to get the block
they belong to) and to blocks (the static link property, if any) so that
GDB can make the proper decisions when dealing with non-local varibale
references.

fe978cb071 C++ keyword cleanliness, mostly auto-generated 
This patch renames symbols that happen to have names which are
reserved keywords in C++.

Most of this was generated with Tromey's cxx-conversion.el script.
Some places where later hand massaged a bit, to fix formatting, etc.
And this was rebased several times meanwhile, along with re-running
the script, so re-running the script from scratch probably does not
result in the exact same output.  I don't think that matters anyway.

43f3e411c4 Split struct symtab into two: struct symtab and compunit_symtab. 
Currently "symtabs" in gdb are stored as a single linked list of
struct symtab that contains both symbol symtabs (the blockvectors)
and file symtabs (the linetables).

This has led to confusion, bugs, and performance issues.

This patch is conceptually very simple: split struct symtab into
two pieces: one part containing things common across the entire
compilation unit, and one part containing things specific to each
source file.

Example.
For the case of a program built out of these files:

foo.c
  foo1.h
  foo2.h
bar.c
  foo1.h
  bar.h

Today we have a single list of struct symtabs:

objfile -> foo.c -> foo1.h -> foo2.h -> bar.c -> foo1.h -> bar.h -> NULL

where "->" means the "next" pointer in struct symtab.

With this patch, that turns into:

objfile -> foo.c(cu) -> bar.c(cu) -> NULL
            |            |
            v            v
           foo.c        bar.c
            |            |
            v            v
           foo1.h       foo1.h
            |            |
            v            v
           foo2.h       bar.h
            |            |
            v            v
           NULL         NULL

where "foo.c(cu)" and "bar.c(cu)" are struct compunit_symtab objects,
and the files foo.c, etc. are struct symtab objects.

So now, for example, when we want to iterate over all blockvectors
we can now just iterate over the compunit_symtab list.

Plus a lot of the data that was either unused or replicated for each
symtab in a compilation unit now lives in struct compunit_symtab.
E.g., the objfile pointer, the producer string, etc.
I thought of moving "language" out of struct symtab but there is
logic to try to compute the language based on previously seen files,
and I think that's best left as is for now.
With my standard monster benchmark with -readnow (which I can't actually
do, but based on my calculations), whereas today the list requires
77MB to store all the struct symtabs, it now only requires 37MB.
A modest space savings given the gigabytes needed for all the debug info,
etc.  Still, it's nice.  Plus, whereas today we create a copy of dirname
for each source file symtab in a compilation unit, we now only create one
for the compunit.

So this patch is basically just a data structure reorg,
I don't expect significant performance improvements from it.

Notes:

1) A followup patch can do a similar split for struct partial_symtab.
I have left that until after I get the changes I want in to
better utilize .gdb_index (it may affect how we do partial syms).

2) Another followup patch *could* rename struct symtab.
The term "symtab" is ambiguous and has been a source of confusion.
In this patch I'm leaving it alone, calling it the "historical" name
of "filetabs", which is what they are now: just the file-name + line-table.

2273f0ac95 change minsyms not to be relocated at read-time 
This removes the runtime offsets from minsyms.  Instead, these offsets
will now be applied whenever the minsym's address is computed.

This patch redefines MSYMBOL_VALUE_ADDRESS to actually use the offsets
from the given objfile.  Then, it updates all the symbol readers,
changing them so that they do not add in the section offset when
creating the symbol.

This change also lets us remove relocation of minsyms from
objfile_relocate1 and also msymbols_sort.

d8d2a3ee47 Normalize on PATH_MAX instead of MAXPATHLEN throughout. 
With the pathmax gnulib module in place, we can use PATH_MAX
consistently throughout, instead of the current mixbag of PATH_MAX and
MAXPATHLEN uses.  It's no longer necessary to include sys/param.h
(supposedly, I can't check all ports touched here) for MAXPATHLEN.

Don't remove sys/param.h from GDB's configure.ac, as later tests in
the file use HAVE_SYS_PARAM_H checks.

Tested on x86_64 Fedora 17.

Also cross-built for --host=i686-w64-mingw32, and --host=i586-pc-msdosdjgpp.

745eb4fdb2 -Wpointer-sign: xcoffread.c. 
../../src/gdb/xcoffread.c: In function ‘xcoff_initial_scan’:
../../src/gdb/xcoffread.c:2982:17: error: pointer targets in assignment differ in signedness [-Werror=pointer-sign]

'debugsec' is a 'bfd_byte *', holding the result of a
bfd_get_full_section_contents.  'info->debugsec' holds the same
contents throughout the whole xcoff read, and everywhere it's used to
read symbol names.  Simply adding a cast feels appropriate.
