[Bug c/46155] Bug with generation of float.h header file on AIX
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46155 --- Comment #13 from Kalle Olavi Niemitalo kon at iki dot fi 2010-11-18 08:10:20 UTC --- Earlier, I thought GCC would eventually have to add some libc-specific definitions to float.h anyway, in order to make FLT_ROUNDS call a function in the C library and map the results correctly, and the IBM fprnd_t and function declarations could then be added at the same time; but according to bug 30569, FLT_ROUNDS is supposed to call a built-in function instead. FLT_EVAL_METHOD has a similar ??? comment above it, but C99 says it shall be a constant expression[s] suitable for use in #if preprocessing directives, so cannot expand to a function call.

ICEs, because printf-puts folding uses XALLOCAVEC for the string literal,
which for very long strings overflows the stack.

We have t (leader) - main-variant (but t is its leader) so we violated /* Always register the main variant first. This is important so we pick up the non-typedef variants as canonical, otherwise we'll end up taking typedef ids for structure tags during comparison. */ if (TYPE_MAIN_VARIANT (t) != t) gimple_register_type (TYPE_MAIN_VARIANT (t)); somehow. This results in endless recursion between the two fns. I have a patch.

For which I will simply add a fn_type member to gimple_call which is controlled by the frontend. We then can treat function pointer conversions as useless (and then the inliner has to decide if the call is suitable for the fndecl).

[Bug debug/46123] [4.5/4.6 Regression] ICE: in output_aranges, at dwarf2out.c:11531 with -feliminate-dwarf2-dups -g
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46123 --- Comment #3 from Jakub Jelinek jakub at gcc dot gnu.org 2010-11-18 13:13:57 UTC --- Created attachment 22446 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=22446 gcc46-pr46123.patch Ugh, this is very ugly. gen_subprogram_die sometimes decides to reuse old_die which was DW_AT_declaration and can be deeply nested in type children, which breaks -feliminate-dwarf2-dups as well as -gdwarf-4 if those are moved to separate CUs (either the comdat ones or .debug_types). The patch fixes this by not reusing the old die if doing one or another way of duplicate removals (perhaps could do an extra check if the old_die is actually in a tree that is going to be moved, which wouldn't be that hard to do for break_out_includes, but would be uglier for .debug_types). Or we could do it always. Unfortunately just doing that leads to crashes, because context_die is NULL and dwarf2out_finish doesn't want to see limbo DIEs with type contexts, so the patch also uses comp_unit_die () in that case. Jason/Cary, what do you think?

That comes after the multilib paths are ready. 15:21 matz But there's (currently) no hook for frontends to include anything into link_command_spec. [...] 15:29 matz Add a new (frontend-driver) macro: LANG_LINK_LIBS (or something). In gcc.c handle it similar to STACK_SPLIT_SPEC. (#ifndef - then empty). In fortran frontend header #define it to '%:include(libgfortran.spec)%lib_gfortran)'. in libgfortran.spec don't define 'lib:' but 'lib_gfortran:' (look at libgomp.spec). 15:30 matz Similar to STACK_SPLIT_SPEC includes adding it to LINK_COMMAND_SPEC. 15:31 matz And then hack long enough until everything works. But at least that way libgfortran.spec will be found in the multilib dirs.

[Bug c/46547] New: internal compiler error when converting a long double complex to a bool
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46547
Summary: internal compiler error when converting a long double
complex to a bool
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: kumbe...@llnl.gov
I have reduced the original application down to a small reproducer. The
following code fails to compile. It works with gcc 4.3.0, intel (icc), sun
(cc), and pathscale (pathcc). PGI's pgcc also generates an ICE with the
function and I'll submit the bug to them as well.
void foo (void) {
_Bool d;
long double _Complex *s;
d = *s++;
}
When you try to compile with gcc version 4.5.1. It generates an error:
foo.c: In function 'foo':
foo.c:5:7: internal compiler error: in gimplify_expr, at gimplify.c:7137
My full output from gcc -v... is:
