[WebAssembly] Change int_wasm_memory_size from IntrNoMem to IntrReadMem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@253147 91177308-0d34-0410-b5e6-96231b3b80d8

[WebAssembly] Update wasm builtin functions to match spec changes. The page_size operator has been removed from the spec, and the resize_memory operator has been changed to grow_memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@252202 91177308-0d34-0410-b5e6-96231b3b80d8

[WebAssembly] Add a memory_size intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@249171 91177308-0d34-0410-b5e6-96231b3b80d8

[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@249364 91177308-0d34-0410-b5e6-96231b3b80d8

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.

[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@252910 91177308-0d34-0410-b5e6-96231b3b80d8
