Hi Geert,
commit a1c48bb160f8368 "Makefile: Fix unrecognized cross-compiler command line options" moved ARCH specific cc option handling before common -Os/O2 setup.
For ARC this had a subtle effect that we can no longer over-ride generic -O2 with -O3, hence a performance regression observed going from 3.13 to 3.18 (the above commit went into 3.16)
I want to understand how to properly fix this. Moving the include of arch makefile will bring back the old issue. I can introduce another option to set default optim level, but only arc/m32r care about it anyways.
Thx, -Vineet
