Description sheepdestroyer 2014-08-07 16:26:30 UTC 
build of https://github.com/dolphin-emu/dolphin with standard flags succeeds
build with LTO and -Ofastsucceed too

However on a Sandybridge cpu, attempt to build with march=native fails with :
   internal compiler error: in vect_get_vec_def_for_operand, at tree-vect-stmts.c:1449

This error was reported to dolphin team here : https://code.google.com/p/dolphin-emu/issues/detail?id=7552

this error only happens when building gui, building no-gui with -march=native succeeds. Would like to try with shared wxwidget but I am blocked by bug 1124402 : https://bugzilla.redhat.com/show_bug.cgi?id=1124402
Comment 3 Jeremy Newton 2014-08-09 16:02:14 UTC 
Hmm I believe this is not a GCC issue but a dolphin issue.  Contact them as well because they can be helpful as well.
Comment 4 sheepdestroyer 2014-08-09 16:05:19 UTC 
did that yesterday, was closed with invalid : https://code.google.com/p/dolphin-emu/issues/detail?id=7552
Comment 5 sheepdestroyer 2014-08-09 16:06:31 UTC 
for reference, I am using rawhide's gcc 4.9.1
Comment 6 Jeremy Newton 2014-08-09 16:19:28 UTC 
Hmmm I didn't see that internal compiler bug line... That's curious. Hopefully the GCC maintained can help
Comment 7 sheepdestroyer 2014-09-15 15:34:22 UTC 
Last update to gcc in rawhide fixed this problem for me
