I don't use -march=native because the compiler failed because I have a hybrid processor with different L1 cache sizes 32 and 48.
Please pick a suitable -march setting and drop the -mno-xxx options from your CFLAGS.
Or simply do *not* USE=custom-cflags, this is handled automatically when you do not enable that.
(In reply to Ionen Wolkens from comment #4) > Or simply do *not* USE=custom-cflags, this is handled automatically when you > do not enable that. (aka it will drop all the -mno-* and pass an roughly equivalent -march=x86-64-v* that will work fine even for those quirky cpus)
