From cf4748f18000ac24fb9d07d493be59cf035c8d68 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Thu, 12 Nov 2015 17:04:33 +0000 Subject: [WebAssembly] Reapply r252858, with svn add for the new file. Switch to MC for instruction printing. This encompasses several changes which are all interconnected: - Use the MC framework for printing almost all instructions. - AsmStrings are now live. - This introduces an indirection between LLVM vregs and WebAssembly registers, and a new pass, WebAssemblyRegNumbering, for computing a basic the mapping. This addresses some basic issues with argument registers and unused registers. - The way ARGUMENT instructions are handled no longer generates redundant get_local+set_local for every argument. This also changes the assembly syntax somewhat; most notably, MC's printing does not use sigils on label names, so those are no longer present, and push/pop now have a sigil to keep them unambiguous. The usage of set_local/get_local/$push/$pop will continue to evolve significantly. This patch is just one step of a larger change. llvm-svn: 252910 --- llvm/lib/Target/WebAssembly/WebAssembly.h | 1 + 1 file changed, 1 insertion(+) (limited to 'llvm/lib/Target/WebAssembly/WebAssembly.h') diff --git a/llvm/lib/Target/WebAssembly/WebAssembly.h b/llvm/lib/Target/WebAssembly/WebAssembly.h index 0109c00ef2f..be6c20c1a7c 100644 --- a/llvm/lib/Target/WebAssembly/WebAssembly.h +++ b/llvm/lib/Target/WebAssembly/WebAssembly.h @@ -27,6 +27,7 @@ FunctionPass *createWebAssemblyISelDag(WebAssemblyTargetMachine &TM, CodeGenOpt::Level OptLevel); FunctionPass *createWebAssemblyCFGStackify(); +FunctionPass *createWebAssemblyRegNumbering(); FunctionPass *createWebAssemblyRelooper(); -- cgit v1.2.3
