--- Comment #12 from ebotcazou at gcc dot gnu dot org 2008-07-27 17:11 --- Aaron, could you update your tree and attemp a clean bootstrap? The fix is supposed to be 2008-07-17 Olivier Hainque [EMAIL PROTECTED] * utils.c (create_var_decl_1): Relax expectations on the PUBLIC_FLAG argument, to apply to references in addition to definitions. Prevent setting TREE_STATIC on externals. (gnat_pushdecl): Always clear DECL_CONTEXT on public externals. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36207

--- Comment #7 from ebotcazou at gcc dot gnu dot org 2008-07-11 21:20 --- I think it's actually the same problem, the patch that has fixed it on other platforms probably doesn't behave the same everywhere. Yep, PE-COFF has a custom binds_local_p hook that doesn't reject DECL_EXTERNAL. That's OK according to http://gcc.gnu.org/ml/gcc/2008-07/msg00205.html Aaron, could you conduct a small experiment? In winnt.c:i386_pe_binds_local_p, just before the 'return true', could you add gcc_assert (!(TREE_CODE (exp) == VAR_DECL DECL_EXTERNAL (exp))); and see whether it triggers during an Ada bootstrap? If so, what's 'exp'? Thanks in advance. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36207

--- Comment #1 from sam at gcc dot gnu dot org 2008-05-12 12:11 ---
Could you post the disassembly of the previous stage get_target_char_size
from targtyps.o? (objdump --source targtyps.o)
On i686-pc-linux-gnu, I get:
Pos
get_target_char_size (void)
{
14: 55 push %ebp
15: 89 e5 mov%esp,%ebp
return CHAR_TYPE_SIZE;
17: b8 08 00 00 00 mov$0x8,%eax
}
1c: 5d pop%ebp
1d: c3 ret
This function is called to initialize Standard_Short_Short_Integer_Size. If
CHAR_TYPE_SIZE is not defined for your target, it defaults to BITS_PER_UNIT
(gigi.h).
