[LiuChen via Phabricator via cfe-commits]

LiuChen3 added inline comments.


================
Comment at: clang/lib/AST/Stmt.cpp:801
+    // since we don't support masm style prefix in backend.
+    if (Instruction.startswith("vex "))
+      MSAsmString += '{' + Instruction.substr(0, 3).str() + '}' +
----------------
>From X86AsmParser, the vex/evex prefix must be the begin of the instructions.
