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

; Test that basic 32-bit integer comparison operations assemble as expected.
[WebAssembly] Use the default alignment for SIMD types. Previously WebAssembly's datalayout string had -v128:8:128. This had been an attempt to declare a certain level of support for unaligned SIMD accesses. However, clang makes its own determinations for SIMD alignment that are independent of the datalayout string, so this wasn't actually meaningful. llvm-svn: 245494

target datalayout = "e-p:32:32-i64:64-n32:64-S128"

[WebAssembly] Switch to a more traditional assembly syntax This new syntax is built around putting each instruction on its own line in a "mnemonic op, op, op" like syntax. It also uses conventional data section directives like ".byte" and so on rather than requiring everything to be in hierarchical S-expression format. This is a more natural syntax for a ".s" file format from the perspective of LLVM MC and related tools, while remaining easy to translate into other forms as needed. llvm-svn: 249364

WebAssembly: update syntax Summary: Follow the same syntax as for the spec repo. Both have evolved slightly independently and need to converge again. This, along with wasmate changes, allows me to do the following: echo "int add(int a, int b) { return a + b; }" > add.c ./out/bin/clang -O2 -S --target=wasm32-unknown-unknown add.c -o add.wack ./experimental/prototype-wasmate/wasmate.py add.wack > add.wast ./sexpr-wasm-prototype/out/sexpr-wasm add.wast -o add.wasm ./sexpr-wasm-prototype/third_party/v8-native-prototype/v8/v8/out/Release/d8 -e "print(WASM.instantiateModule(readbuffer('add.wasm'), {print:print}).add(42, 1337));" As you'd expect, the d8 shell prints out the right value.
