Hello,
With gcc 4.7, on Intel 64 I have trouble using avx register global variables:
register unsigned int something __asm__("xmm2") __attribute__
((__vector_size__ (16)));
works fine, but
register unsigned int something __asm__("ymm2") __attribute__
((__vector_size__ (32)));
results in "error: invalid register name for something"
Is it at all possible to use the YMM registers as variables? If yes, how?
Did you try calling it "xmm2"? -- Marc Glisse
