[Bug debug/42648] [4.5/4.6 Regression] gcc.dg/guality/pr41353-1.c FAILs at -On, n 0
--- Comment #10 from aoliva at gcc dot gnu dot org 2010-06-24 03:34 --- I can only duplicate this problem, even on 4.5 branch, using an old version of GDB, on ia64-linux-gnu. With GDB 7.1, it gets the variables as expected. -- aoliva at gcc dot gnu dot org changed: What|Removed |Added Status|REOPENED|RESOLVED Resolution||WORKSFORME http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42648

--- Comment #9 from aoliva at gcc dot gnu dot org 2010-06-11 10:49 --- Steve, lto and whopr seem to have been introduced in a way that broke VTA. This is not ia64-specific, and it's not what this bug is about. I guess what you're seeing are other cases of lossage, that we might have to look into, but it's better to open separate bugs for them, to avoid confusing the issue further. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42648

--- Comment #7 from aoliva at gcc dot gnu dot org 2010-06-10 18:50 --- Steve, I only see problems on ia64 at -O3, and that's because VTA is disabled when selective scheduling is enabled. Uros, I can't duplicate the problem with a cross compiler for alpha: the debug info in the assembly output and in the vartrack dump looks just right to me. I'm not sure how to proceed, maybe post evidence that GCC is actually producing incorrect debug info, rather than that say the assembler is mangling it or GDB is misinterpreting it? Richard, if you can still duplicate the problem on your end, can you help? debug bind stmts for incoming args are not expected at the entry point, they're only inserted when the function is inlined or early in the var-tracking pass. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42648

--- Comment #8 from sje at cup dot hp dot com 2010-06-10 19:27 --- I see pr41353-1.c failures with -O2 -flto and -O2 -fwhopr as well as with -O3. I also see other guality tests fail with non -O3 flags. See http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg00991.html -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42648
