Hello, Is there a inline asm constraint for ymm0 (AVX) register that works same way as "Yz"() for xmm0 (SSE)? I have to use “x”() at the moment, but it loads to an arbitrary register that should be moved to ymm0. The best way to do this would be just to extend “Yz” so that it could handle any type of *mm0 registers. Or maybe use something like “x0”? -- View this message in context: http://gcc.1065356.n5.nabble.com/inline-asm-constraint-for-ymm0-register-analogous-to-Yz-for-xmm0-tp1096515.html Sent from the gcc - Help mailing list archive at Nabble.com.
