Dear all,
My code uses the gcc __builtin_cpu_supports('avx") for preventing using AVX
instructions on non-AVX computers.
However, it seems that this function always returns true on any non-AVX
processor (such as 1st generation i7) then the app crash on the first AVX
instruction.
Is this function only returning the AVX support enabled at compile time or
is it really querying the CPU? Is it implemented in MinGW-w64?
I'm using MinGW-w64 4.9.1 pthreads seh
Thanks!
Etienne
