* [WebAssembly] Add return type annotations in fast isel.Dan Gohman2017-01-091-0/+3
| | | | llvm-svn: 291498
* [WebAssembly] Don't old negative load/store offsets in fast-isel.Dan Gohman2016-12-221-9/+24
| | | | | | | WebAssembly's load/store offsets are unsigned and don't wrap, so it's not valid to fold in a negative offset. llvm-svn: 290342
* IR: Change the gep_type_iterator API to avoid always exposing the "current" ↵Peter Collingbourne2016-12-021-1/+1
| | | | | | | | | | | | | type. Instead, expose whether the current type is an array or a struct, if an array what the upper bound is, and if a struct the struct type itself. This is in preparation for a later change which will make PointerType derive from Type rather than SequentialType. Differential Revision: https://reviews.llvm.org/D26594 llvm-svn: 288458
* [WebAssembly] Reorder load/store operands to match binary encoding.Dan Gohman2016-10-251-4/+4
| | | | | | | The p2align operand of a load/store is encoded before the offset operand; reorder the MachineInstr operands accordingly. llvm-svn: 285044
* [WebAssembly] Add an option to make get_local/set_local explicit.Dan Gohman2016-10-241-2/+2
| | | | | | | | | | This patch adds a pass, controlled by an option and off by default for now, for making implicit get_local/set_local explicit. This simplifies emitting wasm with MC. Differential Revision: https://reviews.llvm.org/D25836 llvm-svn: 285009
* [WebAssembly] Fix for 0xc call_indirect changesDerek Schuff2016-10-211-9/+9
| | | | | | | | | | | | | | | | | Summary: Need to reorder the operands to have the callee as the last argument. Adds a pseudo-instruction, and a pass to lower it into a real call_indirect. This is the first of two options for how to fix the problem.

* [WebAssembly] Remove the output operand from stores.Dan Gohman2016-10-061-10/+1
| | | | | | | | | Per spec changes, store instructions in WebAssembly no longer have a return value. Update the instruction descriptions. Differential Revision: https://reviews.llvm.org/D25122 llvm-svn: 283501
* [WebAssembly] Check return value of getRegForValue in FastISelDerek Schuff2016-08-041-0/+13
| | | | | | | | | | | | Previously, FastISel for WebAssembly wasn't checking the return value of `getRegForValue` in certain cases, which would generate instructions referencing NoReg. This patch fixes this behavior. Patch by Dominic Chen Differential Revision: https://reviews.llvm.org/D23100 llvm-svn: 277742
* [WebAssembly] Initial SIMD128 support.Derek Schuff2016-08-021-4/+76
| | | | | | | | | | | | | | Kicks off the implementation of wasm SIMD128 support (spec: https://github.com/stoklund/portable-simd/blob/master/portable-simd.md), adding support for add, sub, mul for i8x16, i16x8, i32x4, and f32x4. The spec is WIP, and might change in the near future. Patch by João Porto Differential Revision: https://reviews.llvm.org/D22686 llvm-svn: 277543
* [WebAssembly] Fast-isel support for calls, arguments, and selects.Dan Gohman2016-05-121-51/+324

* [WebAssembl] Implement enough of fast-isel to run the comparison tests.Dan Gohman2016-05-111-98/+389

* [WebAssembly] Preliminary fast-isel support.Dan Gohman2016-05-101-4/+542
