[Bug other/41255] New: [4.5 Regression] Release notes: Advice to use GDB later than 6.8
[One] need[s] the upcoming GDB to debug GCC 4.5 compiled code anyway, because older GDBs mishandle DW_CFA_restore_state which is now used all around in .eh_frame, otherwise backtraces really don't work. [1] Thus one should document this in the GCC 4.5 release notes. GDB 7.0 will support this, for GDB 6.8 one can use the patches at [2].

While the program fails for: prc_id = foobar ! ASSIGNMENT(=) [but no TBP generic] n_in = prc_lib%get_n_in(2) ! Proc-pointer component it works if one reverses the order, i.e. n_in = prc_lib%get_n_in(2) prc_id = foobar which might be an indication that it depends on the walking of the tree or that something else gets corrupt.

--- Comment #2 from rguenth at gcc dot gnu dot org 2009-09-04 11:23 --- We remove the alias target during applying the inline transform. And we fail to remove unreachable alias pairs there. We usually do that from cgraph_remove_unreachable_nodes. Once again this shows that these on-the-side things do not play well with the cgraph. Why can't we move all the alias-pair stuff to first class cgraph nodes instead? Likewise I'd represent asm-thunks in the cgraph and only expand them during expansion when we know they are really necessary. Anyway - I'm trying to fix this bug by removing unreachable alias pairs which is hopefully possibly in an IPA way - this queued IPA transforms in cfun looks a bit fishy. -- rguenth at gcc dot gnu dot org changed: What|Removed |Added CC||hubicka at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41257

[Bug target/40905] GCC creates invalid executable with auto-imported DLL and __attribute__((cold))
--- Comment #5 from ktietz at gcc dot gnu dot org 2009-09-04 13:27 --- (In reply to comment #4) (In reply to comment #2) Is it possible that it triggers the exception trying to write in text.unlikely which is READONLY? Exactly. This is a linker, not a compiler issue. If you are using a relatively recent binutils and mingw run time, the addition of the switch -Wl,--enable-runtime-pseudo-reloc-v2 should get around the READONLY problem. Otherwise, you could always just add __declspec (dllimport) to extern int foo[2]; and so retain portability with the rest of the PE-COFF world. Danny Right, this is a linker issue (or runtime issue of pseudo-relocation). But newer mingw32's runtime uses new code for v1 relocations, too. So for it, this issue should be solved, too. So can we close this bug? Cheers, Kai -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40905

[Bug bootstrap/41241] [4.5 regression] bootstrap comparison failure
--- Comment #38 from vmakarov at redhat dot com 2009-09-04 15:25 --- Finally, I think I found what is the reason for all these bootstrap failures. I've changed code dealing with register preferences. Now regnfo::reg_pref is not null from the start and some passes (now it is regmove) using reg_(preferred,alternative)_class returns uninitialized data instead of GENERAL_REGS as before. I don't see sense for these passes to use this info (it was in the old RA too: regclass initializing reg_pref was called only in local-alloc first time) because code in the passes assumes that reg_preferred_class returns right class (not GENERAL_REGS). I'll work for a work around. I hope to send it today. The right solution will take more time (may be week or two). I apologize for all that trouble I cause with my patch. But it permitted to find some pitfalls in RA (and the old one too). Thanks for all your help. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41241

Since alias-improvements have brought aliasing information to the early stages, I am now testing whether we can move pass_stdarg up right before early SRA. I'm running the test on an x86_64 now, will try to do it on some other platform if the test finishes fine. If it doesn't work for some reason, I will tend to fix this by a hack very similar to the patch in the email linked above. -- jamborm at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |jamborm at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2009-08-25 21:53:10 |2009-09-04 18:45:26 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41089

--- Comment #9 from jvdelisle at gcc dot gnu dot org 2009-09-04 20:16

Putting the standards discussion aside, this test case actually uncovered a
real bug. In list_read.c, eat_line does nothing for internal units.
If the test had used a real file, the comment would have been skipped and we
would have never heard about this problem. The following patch I have
regression tested and will commit after labor day.
