The build_address_symbolic funnction filters out data symbols if
their size is set to zero. But the problem is that the COFF symbol
table (for instance) does not provide any size information, leaving
the size to its default value of zero, thus always triggering
the filter.
This shows up when trying to print the address of a global variable
when debugging a Windows executable, for instance.
gdb/ChangeLog:
* symtab.h (struct minimal_symbol) [has_size]: New field.
(MSYMBOL_SIZE): Adjust to forbid macro from being used as lvalue.
(SET_MSYMBOL_SIZE, MSYMBOL_HAS_SIZE): New macros.
* printcmd.c (build_address_symbolic): Only filter out zero-sized
minimal symbols if the symbol's size is actually known.
* minsyms.c (prim_record_minimal_symbol_full): Adjust setting
of msymbol's size field. Add comment.
* elfread.c (elf_symtab_read, elf_rel_plt_read): Use
SET_MSYMBOL_SIZE to set the minimal symbol size.
gdb/ChangeLog:
* minsyms.c (install_minimal_symbols): Use memset to fill entire
minimal_symbol struct object, rather than setting some of its
fields one by one.
gdb/ChangeLog:
* c-typeprint.c (c_type_print_varspec_prefix): Pass through the
passed_a_ptr flag when displaying typedef types.
gdb/testsuite/ChangeLog:
* gdb.base/ptype.exp: Test ptype on a pointer to a typedef.

common-page-size alignment, ensure we are on a new max-page-size
page.

Assuming the following declarations:
type Discriminants_Record (A : Integer; B : Boolean) is record
C : Float;
end record;
Z : Discriminants_Record := (A => 1, B => False, C => 2.0);
If variable Z is not used, and the compiler optimizes it out,
GDB would crash as follow:
(gdb) print Z
/[...]/gdb/valops.c:1121: internal-error: Unexpected lazy value type.
This is because the ada-lang module forgot to set the optimized_out
flag in the value returned by ada_evaluate_subexp during the value's
"fixing" process. Later on, when trying to print the resulting value,
GDB finds that the value is still lazily allocated, and thus tries to
fetch it. But this is not allowed for not_lval values, hence the internal
error.
gdb/ChangeLog:
* ada-lang.c (coerce_unspec_val_to_type): Make sure that
the optimized_out flag is preserved.
gdb/testsuite/ChangeLog:
* gdb.ada/optim_drec: New testcase.

pubtypes_object_.
* gdbtypes.h (BOOL_PTR_CONVERSION_BADNESS): Rename to ...

permitted by the standard.

(enum my_enum): New enumeration.
(main): Add calls to foo1_7 with various
permitted arguments.
* gdb.cp/converts.exp: Add tests for boolean
conversions permitted by the standard.
orphan sections to .data and .bss output sections, not just .text.
When giving up on finding a suitable output section, attach to any
output section other than .MMIX.reg_contents, if it exists.
* scripttempl/mmo.sc: Move output debug sections to just before
.MMIX.reg_contents. Add .gnu.attributes. Add new . = . NOP
assignments and move end-of-section provide-symbols after them
to force the end-of-section symbols to the address after orphan
placement. Add SORT_NONE to .init and .fini sections.
