WebAssembly: add basic int/fp instruction codegen. Summary: This patch has the most basic instruction codegen for 32 and 64 bit int/fp. Reviewers: sunfish Subscribers: llvm-commits, jfb Differential Revision: http://reviews.llvm.org/D11193 llvm-svn: 242201

WebAssembly: add basic floating-point tests Summary: I somehow forgot to add these when I added the basic floating-point opcodes. Also remove ceil/floor/trunc/nearestint for now, and add them only when properly tested. Subscribers: llvm-commits, sunfish, jfb Differential Revision: http://reviews.llvm.org/D11927 llvm-svn: 244562

WebAssembly: implement comparison. Some of the FP comparisons (ueq, one, ult, ule, ugt, uge) are currently broken, I'll fix them in a follow-up. Reviewers: sunfish Subscribers: llvm-commits, jfb Differential Revision: http://reviews.llvm.org/D11924 llvm-svn: 244665

WebAssembly: floating-point comparisons Summary: D11924 implemented part of the floating-point comparisons, this patch implements the rest: * Tell ISelLowering that all booleans are either 0 or 1. * Expand the eq/ne/lt/le/gt/ge floating-point comparisons to the canonical ones (similar to what Mips32r6InstrInfo.td does). * Add tests for ord/uno. * Add tests for ueq/one/ult/ule/ugt/uge. * Fix existing comparison tests to remove the (res & 1) code, which setBooleanContents stops from generating.
