From: "davek at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug middle-end/46674] [4.6 Regression] Weak alias is mistakenly optimized away Date: Tue, 07 Dec 2010 04:31:00 -0000 [thread overview] Message-ID: <bug-46674-4-IGg1xMb3Ct@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-46674-4@http.gcc.gnu.org/bugzilla/> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46674 Dave Korn <davek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED CC| |davek at gcc dot gnu.org Resolution|FIXED | --- Comment #9 from Dave Korn <davek at gcc dot gnu.org> 2010-12-07 04:31:08 UTC --- Not fixed on platforms where USER_LABEL_PREFIX is non-empty. On i686-pc-cygwin: FAIL: gcc.dg/pr46674.c scan-assembler wobbly Stripping the star isn't enough, because behind that star it's a fully-qualified assembler name, i.e. prefixed if prefixes are in use. The alias names are C level symbols. We can't just compare them; this is the same as the lto symtab problem. We should be able to fix this fully using the mangle_assembler_name hook I'm testing a patch for (http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00403.html).
