Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user. Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands. For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1 though andpd has 2 possible matching formats - andpd xmm, xmm/m128 Patch by: ziv.izhar@intel.com Differential Revision: http://reviews.llvm.org/D14607 llvm-svn: 254607
