Subject: WebAssembly: assert that there aren't any constant pools
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c3a33b1b54d66b5c6db12d93fc556f025bc69971;p=oota-llvm.git

WebAssembly: assert that there aren't any constant pools

WebAssembly will either use globals or immediates, since it's a virtual ISA.
