okay, that is just wierd.
I used
gcc -march=native -E -v - </dev/null 2>&1 | grep cc1
to expand what gcc thinks -march=native means for use with distcc. I figured this why I have all the benefit of -march=native without the drawbacks of using it with distcc
it expands to:
CFLAGS="-Os -pipe -frecord-gcc-switches -ggdb -march=corei7-avx -mcx16 -msahf -mno-movbe -maes -mpclmul \
-mpopcnt -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mavx -mno-avx2 \
-msse4.2 -msse4.1 -mno-lzcnt -mno-rdrnd -mno-f16c -mno-fsgsbase --param l1-cache-size=32 \
--param l1-cache-line-size=64 --param l2-cache-size=3072 -mtune=corei7-avx -fno-strict-overflow -fPIE -fstack-protector-all"
really odd that it fails to build with the expanded version of -march=native but not with -march=native itself.
I will call this invalid unless someone else cares.
