Oliver Metz <oliver.metz at gmx dot de> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |oliver.metz at gmx dot de --- Comment #6 from Oliver Metz <oliver.metz at gmx dot de> 2011-06-03 09:32:44 UTC --- Thanks Ian for your help. This bug is still valid for gcc-4.6.0. When --enable-target-optspace is set config/mt-ospace is included and overwrites the configured CFLAGS_FOR_TARGET variable. config/mt-ospace: # Build libraries optimizing for space, not speed. CFLAGS_FOR_TARGET = -g -Os CXXFLAGS_FOR_TARGET = -g -Os So it's not possible to optimize the target libs for the target (e.g. -march=4kc -msoft-float).
