* [WebAssembly] Initial Disassembler.Sam Clegg2018-05-101-5/+121
| | | | | | | | | | | | | | | | | | | | | This implements a new table-gen emitter to create tables for a wasm disassembler, and a dissassembler to use them. Comes with 2 tests, that tests a few instructions manually. Is also able to disassemble large .wasm files with objdump reasonably. Not working so well, to be addressed in followups: - objdump appears to be passing an incorrect starting point. - since the disassembler works an instruction at a time, and it is disassembling stack instruction, it has no idea of pseudo register assignments. These registers are required for the instruction printing code that follows. For now, all such registers appear in the output as $0.

* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-011-1/+1
| | | | | | | | | | | | | | | | We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all. Patch produced by for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done Differential Revision: https://reviews.llvm.org/D46290 llvm-svn: 331272
* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [WebAssembly] Remove old experimental disassemler code.Dan Gohman2017-02-111-84/+2
| | | | | | | Remove support for disassembling an old experimental wasm binary format, which is no longer in use anywhere. llvm-svn: 294809
* [WebAssembly] Add instruction definitions for drop and get/set_global.Dan Gohman2017-02-021-0/+1

* [WebAssembly] Add an option to make get_local/set_local explicit.Dan Gohman2016-10-241-0/+1
| | | | | | | | | | 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
* Move the global variables representing each Target behind accessor functionMehdi Amini2016-10-091-2/+2
| | | | | | | | This avoids "static initialization order fiasco" Differential Revision: https://reviews.llvm.org/D25412 llvm-svn: 283702
* [WebAssembly] Rename OPERAND_FP32IMM to OPERAND_F32IMM.Dan Gohman2016-10-031-2/+2
| | | | | | | WebAssembly documentation consistently says "f32" rather than "fp32" to describe 32-bit floating-point. llvm-svn: 283146

* [WebAssembly] Implement a prototype instruction encoder and disassembler.Dan Gohman2016-01-121-0/+148
This is using an extremely simple temporary made-up binary format, not the official binary format (which isn't defined yet). llvm-svn: 257440
