[Comment 1 Jakub Moc (RETIRED) 2006-12-30 15:35:41 UTC]

Well, it won't work... Stick -fomit-frame-pointer into your C[XX]FLAGS and/or use >=-O1

[Comment 2 Jakub Moc (RETIRED) 2006-12-30 15:45:47 UTC]

Also wondering what's this hardcoded junk doing there: 
-O3 -ffast-math -funroll-loops -mtune=pentium2

[Comment 3 Andrej Kacian (RETIRED) 2007-01-09 01:50:10 UTC]

@video: is there anything that can be done here? (other than diving into asm) Perhaps this should be reported upstream.

[Comment 4 Christian Faulhammer (RETIRED) 2007-02-08 18:46:51 UTC]

-O0 is now replaced with -O1.  And flag-o-matic.eclass is inherited now.
