Subject: WebAssembly: comment out .globl when printing textual assembly
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=42e1a86e8103dcfc51e685f01e0a5a90ee11f27b;p=oota-llvm.git

WebAssembly: comment out .globl when printing textual assembly

Do the same for .weak (not implemented for now, but may as well to it). Update comment string to two semicolons.
