Just finished all 3. Here was my experience. Hardware is PIII with
512 MB RAM, Intel i810 chipset.
glibc: passed tests with -O3 -march=i686 -pipe, didn't like -march=pentium3.
gcc: this was the pickiest. Passed all tests (except va-arg25) with
-O2 -march=i386 -pipe. I don't even know if i386 causes any
optimization. It did not like -march=i686. Didn't try any other -O
binutils: passed test with -O2 -march=pentium3 -pipe. Seems to be the
most resilient to optimization settings for me. Again, didn't try any
other -O settings. Would like to try again with -O3 to see what
Hope that helps some.
