Subject: MC: collapse emission of producer
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1919beac0dc44cf3e41dbaa7d3616e6be6d0d010;p=oota-llvm.git

MC: collapse emission of producer

Rather than use three EmitBytes, concatenate the string at compile time,
constructing a single StringRef and emitting the data in one shot.  This also
creates nicer assembly output.  NFC.
