Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Sun Feb 20 14:38:32 2011 +0000 x86: use raw opcode for xgetbv instruction This allows the CPU detection to work with assemblers not supporting the xgetbv mnemonic. These include clang and some BSD versions. All AVX code will be written for yasm, where the main assembler is not involved.
