[PATCH] D31174: [X86][MS-compatability] allow MS TYPE/SIZE/LENGTH operators as a part of a compound expression

[coby via Phabricator via cfe-commits]

coby created this revision.

This patch introduces X86AsmParser with the ability to handle the 
aforementioned ops within compound "MS" arithmetical expressions. Currently - 
only supported as a stand alone Operand, e.g.:
"TYPE X"
now allowed :
"4 + TYPE X * 128"
