# RUN: llvm-mc -triple x86_64-pc-win32 %s | FileCheck %s
[X86] Fix register parsing in .seh_* in Intel syntax Previously, the parser checked for a '%' prefix to indicate a register. In Intel syntax mode, LLVM does not print a '%' prefix on registers, so LLVM could not parse its own assembly output. Instead, require that register numbers be integer literals, or at least start with an integer literal, which is consistent with .cfi_* directive register parsing. llvm-svn: 375287
