Hi @daniel-santos,

is this project dead? If so, could you add a banner or something saying so and link to https://github.com/hartwork/resolve-march-native for a potential alternative?

Thanks and best, Sebastian

On my machine，using command:
$ gcc -v -E -x c -march=native -mtune=native - < /dev/null 2>&1 | grep cc1 | perl -pe 's/^.* - //g;' | perl -pe 's/-mno-.*? //g;''
got a long sting,
-march=westmere -mmmx -msse -msse2 -msse3 -mssse3 -mcx16 -msahf -mpopcnt -msse4.2 -msse4.1 -mfxsr --param l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=3072 -mtune=westmere

But, distccflags script only show me a very short result:
CFLAGS="-march=westmere -mno-aes -mno-pclmul"

Can distccflag's result replace the above long result? Or just add the missing part?
