Subject: No functionality change. Rename emitGCNO() to the more sensible
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=64a0a33307723957bf2f15e3181a290853c6f833;p=oota-llvm.git

No functionality change. Rename emitGCNO() to the more sensible
emitProfileNotes(), similar to emitProfileArcs(). Also update its comment.

Also add a comment on Version[4] (there will be another comment in clang later),
and compress lines that exceeded 80 columns.
