X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d6d9dd9f5e950383b7040a864bd8e004f95bcc91;p=oota-llvm.git

fix a crash on:

let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {

we now get:

X86InstrCompiler.td:653:52: error: Expected class, def, defm, multiclass or let definition
let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {
                                                   ^
