* Add shared memories (#1069)Derek Schuff2017-06-271-2/+7
| | | | | Begin to implement wasm threading proposal in https://github.com/WebAssembly/threads/blob/master/proposals/threads/Overview.md This PR just has shared memory attribute with wast and binary support.
* Exporting/importing debug location information from .wast/.asm.js/.s formats ↵Yury Delendik2017-06-011-2/+41
| | | | | | | | (#1017) * Extends wasm-as, wasm-dis and s2wasm to consume debug locations. * Exports source map from asm2wasm
* Parsing fixes (#990)Alon Zakai2017-05-021-4/+11
| | | | | | | | | | * properly catch a bunch of possible parse errors, found by afl-fuzz * clean up wasm-interpreter, use WASM_UNREACHABLE instead of abort * detect duplicate names in function names section * detect duplicate export names
* Extensible name section (#933)pipcet2017-04-131-1/+8
| | | | | | | | | | | | | See https://github.com/WebAssembly/binaryen/issues/914. * extensible name section support: read function names, too * c-api-unused-mem.txt: change expected size to match new name section * * check subsection size matches * print warning for unknown name subsections (including the local section)
* Wasm h to cpp (#926)jgravelle-google2017-03-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | * Move WasmType function implementations to wasm.cpp * Move Literal methods to wasm.cpp * Reorder wasm.cpp shared constants back to top * Move expression functions to wasm.cpp * Finish moving things to wasm.cpp * Split out Literal into its own .h/.cpp. Also factor out common wasm-type module * Remove unneeded/transitive includes from wasm.h * Add comment to try/check methods * Rename tryX/checkX methods to getXOrNull * Add missing include that should fix appveyor build breakage * More appveyor

| | | | | | | | | | | | | | | | | | | | | * Renumber opcodes for 0xd * Unified type encoding * Add reserved flags fields to host instructions and call_indirect * Rename flags->reserved * Fix line numbers in wast parser Also don't throw if the memory is defined in the same Element as the export of memory (the validity is checked later anyway). * Skip spec binary.wast The spec testsuite is still on 0xc, so 0xd doesn't match. In order to update to 0xd we need to implement some additional functionality for the import test, namely (register)

|
* Don't create table sections for imported tables (#756)Derek Schuff2016-10-111-1/+3
| | | Previously the Print pass searched the imports for a table import and skipped printing a local table declaration if found. Instead this refactors to make importation explicit, and also create importation records (previously we were inconsistent about whether such records were created in the IR depending on the wast syntax).
* Binary 0xc: Remove arity on return instruction (#740)Derek Schuff2016-10-041-4/+2
| | | | Also skip binary roundtrip on stacky spec tests
* Write global mutability into wasm binary (#739)Derek Schuff2016-10-041-3/+6
| | | | | For compatibility with 0xc Also update opcode for get_global
* More binary updates for 0xc (#733)Derek Schuff2016-10-031-26/+51
| | | | | | | | | | | | | | | Refine tables to explicitly exist or not. Previously they were printed or encoded if it had any segments, or an initial or max size. However tables can be defined but empty, so we had a special hack that defined an empty segment when we really just wanted an empty table. Now, just make the existence explicit. Update Function table encoding for 0xc (Table and Element sections) Add end opcodes after function bodies (these are consumed by getMaybeBlock with the same behavior that it had before when it reached the function end, so no explicit decode) Update call_indirect encoding for 0xc (no arity, call target is last)

* Type check block/loop/if sigs (#717)Alon Zakai2016-09-281-40/+12
| | | | | | * type check using block/loop/if types provided in text and binary formats. * print if and loop sigs which were missing. * remove dsl from OptimizeInstructions as after those changes it needs rethinking.
* Update binary encoding for block, loop, and if signatures (#711)Derek Schuff2016-09-271-26/+67
| | | | | | Also updates the tests and has a few other changes for binary 0xc: Update nop/unrechable opcodes Fix for "name" section

* Update binary encodings for call instructions and segments (#706)Derek Schuff2016-09-221-9/+10
| | | | | * Call instructions no longer encode the arity * Segments encode the linear memory index (0 for MVP)
* Update binary format toward 0xc (#704)Derek Schuff2016-09-221-88/+137
| | | | | | Updates section headers and formats for type, import, function, table, memory, and export sections, as well as "names" section, which is now a user section.
