* fix wait and wake binary format support, they have alignments and offsets
* don't emit unreachable parts of atomic operations, for simplicity and to avoid special handling
* don't emit atomic waits by default in the fuzzer, they hang in native vm support

* Skeleton of a beginning of o2wasm, WIP and probably not going to be used
* Get building post-cherry-pick
* ast->ir, remove commented out code, include a debug module print because linking
* Read linking section, print emscripten metadata json
* WasmBinaryWriter emits user sections on Module
* Remove debugging prints, everything that isn't needed to build metadata
* Rename o2wasm to lld-metadata
* lld-metadata support for outputting to file
* Use tables index instead of function index for initializer functions
* Add lld-emscripten tool to add emscripten-runtime functions to wasm modules (built with lld)
* Handle EM_ASM in lld-emscripten
* Add a list of functions to forcibly export (for initializer functions)
* Disable incorrect initializer function reading
* Add error printing when parsing .o files in lld-metadata
* Remove ';; METADATA: ' prefix from lld-metadata, output is now standalone json
* Support em_asm consts that aren't at the start of a segment
* Initial test framework for lld-metadata tool
* Add em_asm test
* Add support for WASM_INIT_FUNCS in the linking section
* Remove reloc section parsing because it's unused
* lld-emscripten can read and write text
* Add test harness for lld-emscripten
* Export all functions for now
* Add missing lld test output
* Add support for reading object files differently
Only difference so far is in importing mutable globals being an object
file representation for symbols, but invalid wasm.
* Update help strings
* Update linking tests for stackAlloc fix
* Rename lld-emscripten,lld-metadata to wasm-emscripten-finalize,wasm-link-metadata
* Add help text to header comments
* auto& instead of auto &
* Extract LinkType to abi/wasm-object.h
* Remove special handling for wasm object file reading, allow mutable globals
* Add braces around default switch case
* Fix flake8 errors
* Handle generating dyncall thunks for imports as well
* Use explicit bool for stackPointerGlobal
* Use glob patterns for lld file iteration
* Use __wasm_call_ctors for all initializer functions

Emits binary size and opcode counts for each function, which helps investigating what's taking up space in a wasm binary.

Instead merge constant-offset segments if we must in order to stay under the limit.
If we can't - too many non-constant-offset segments - then issue a warning.

* Check if there is a currFunction before using it (we need it for some stacky code; a valid wasm wouldn't need a function in that location anyhow, as what can be put in a memory/table offset is very limited).
* Huge alignment led us to do a power of 2 shift that is undefined behavior.
Also adds a test facility to check we don't crash on testcases.

* remove unneeded code to handle a br to the return from the function. Now that we use getBlockOrSingleton there, it does that for us anyhow
* fix a fuzz bug of popping from outside a block

The IR is indeed a tree, but not an "abstract syntax tree" since there is no language for which it is the syntax (except in the most trivial and meaningless sense).

* optimize wasm reading: use a set of the breaks we've seen, don't rescan blocks to see if they have breaks to them

|
| |
* don't emit a toplevel block if we don't need to, as in wasm it is a list context
* don't create unnecessary blocks in wasm reading

These are not atomic operations, but are added with the atomic operations to keep from having to define atomic versions of all the sign-extending loads (an atomic zero-extending load + signext operation can be used instead).

Ignoring unreachable code in wasm binaries lets us avoid corner cases with unstructured code in wasm binaries that is a poor fit for Binaryen's structured IR.

Emit valid wasm binaries even for corner cases of unreachable code.
* emit an unreachable after a node that pushes a value that has unreachable type (where wasm type checking would have pushed a concrete type)
* conversely, as a hack, emulate the wasm polymorphic stack mode by not emptying the stack when it has one element and that element is unreachable. this lets further pops work (all returning an unreachable element)

threads proposal (#1082)
Also leave a stub (but valid) visitAtomicRMW in the visitor template so that not all visitors need to implement this function yet.

* show a clear error on nulls in inline strings (which we don't support, and in general are not seen in practice, but are technically valid wasm) in binary format reading

Add IR, wast and binary support for atomic loads and stores.
Currently all IR generated by means other than parsing wast and binary files always generates non-atomic accesses, and optimizations have not yet been made aware of atomics, so they are certainly not ready to be used yet.

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.

(#1017)
* Extends wasm-as, wasm-dis and s2wasm to consume debug locations.
* Exports source map from asm2wasm
|
| |
|
|
|
|
|
|
| |
* values cannot flow through an if without an else, they never return a value
* check pass tests in pass-debug mode too
* add missing finalization in binary reading

* fix type of drop, set_local, set_global, load, etc: when operand is unreachable, so is the node itself
* support binary tests properly in test/passes
* fix unreachable typing of blocks with no name and an unreachable child
* fix continue emitting in asm2wasm
* properly handle emitting of unreachable load

* document new difference between binaryen IR and wasm
* fix relooper missing finalize
* add a bunch of tests
* don't assume that test/*.wast files print to themselves exactly; print to from.wast. this allows wast tests with comments in them
* emit unreachable blocks as (block .. unreachable) unreachable
* if without else and unreachable ifTrue is still not unreachable, it should be none
* update wasm.js
* cleanups
* empty blocks have none type
