* [WebAssembly] Massive instruction renamingThomas Lively2019-01-081-45/+45
| | | | | | | | | | | | | | | Summary: An automated renaming of all the instructions listed at https://github.com/WebAssembly/spec/issues/884#issuecomment-426433329 as well as some similarly-named identifiers.

* [WebAssembly] Added default stack-only instruction mode for MC.Wouter van Oortmerssen2018-08-271-1/+1
| | | | | | | | | | | | | | | | | | | | | Summary: Made it convert from register to stack based instructions, and removed the registers. Fixes to related code that was expecting register based instructions. Added the correct testing flag to all tests, depending on what the format they were expecting so far. Translated one test to stack format as example: reg-stackify-stack.ll tested: llvm-lit -v `find test -name WebAssembly` unittests/MC/* Reviewers: dschuff, sunfish Subscribers: sbc100, jgravelle-google, eraman, aheejin, llvm-commits, jfb Differential Revision: https://reviews.llvm.org/D51241 llvm-svn: 340750

* [WebAssembly] Remove WASM_STACK_POINTER.Dan Gohman2017-12-061-2/+0
| | | | | | | WASM_STACK_POINTER and the .stack_pointer directive are no longer needed now that the stack pointer global is an import. llvm-svn: 319956
* [WebAssembly] Implement WASM_STACK_POINTER.Dan Gohman2017-12-051-0/+2
| | | | | | | Use the .stack_pointer directive to implement WASM_STACK_POINTER for specifying a global variable to be the stack pointer. llvm-svn: 319797
* [WebAssembly] Use __stack_pointer global when writing wasm binarySam Clegg2017-06-161-12/+12
| | | | | | | | | | | | | | | | | | This ensures that symbolic relocations are generated for stack pointer manipulations. These relocations are of type R_WEBASSEMBLY_GLOBAL_INDEX_LEB. This change also adds support for reading relocations of this type in WasmObjectFile.cpp. Since its a globally imported symbol this does mean that the get_global/set_global instruction won't be valid until the objects are linked that global used in no longer an imported global.

* [WebAssembly] Add support for using a wasm global for the stack pointer.Dan Gohman2017-02-241-45/+57
| | | | | | | This replaces the __stack_pointer variable which was allocated in linear memory. llvm-svn: 296201
* [WebAssembly] Emit a BasePointer when we have overly-aligned stack objectsDerek Schuff2016-11-071-0/+137
Because we shift the stack pointer by an unknown amount, we need an additional pointer. In the case where we have variable-size objects as well, we can't reuse the frame pointer, thus three pointers. Patch by Jacob Gravelle Differential Revision: https://reviews.llvm.org/D26263 llvm-svn: 286160
