Bug ID: 380869
Summary: valgrind has issues with mesa comiled with
CFLAGS="-march=corei7"
Product: valgrind
Version: 3.13 SVN
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: austinengl...@gmail.com
Target Milestone: ---
While running wine's direct3d tests (which invoke OpenGL), I noticed that I got
a lot of crashes, with poor debugging info:

This is on gentoo, and llvm/clang/mesa all have USE=debug (mesa also has
USE=valgrind enabled).
After debugging with some Wine guys, it was pointed out to me that march=native
can cause issues. Removing march=core17 from my system CFLAGS and recompiling
mesa (nothing else), I got much better info from valgrind:
../../../tools/runtest -q -P wine -T ../../.. -M d3d8.dll -p d3d8_test.exe.so

Let me know if I can provide more info to help debug this.
