| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Adds command-line argument to build-js.sh for specifying the location of Emscripten. Also spreads out program arguments on separate lines * Exposes WasmBinaryWriter and BufferWithRandomAccess in the JS API to allow writing WASM modules and access the produced bytes via the JS API * Updates bin/binaryen.js and bin/wasm.js from changes to build-js.sh * Adds exclude patterns to .gitignore for some files generated by build-js.sh and .DS_Store for macOS * Changes build-js.sh to use EMSCRIPTEN env var instead of a command-line argument to provide the path to emscripten * Improvements to JS builds - Adds -g flag to build-js.sh that will build unoptimized and unmangled versions of binaryen.js and wasm.js (output has a "-g.js" suffix to allow co-existence with regular optimized builds). - Enables closure compiler for non-debug builds - Adds browser test for s-expression parser + WASM code gen (requires wasm to be enabled in the browser.) - Adds iterator interface to BufferWithRandomAccess (when Symbol.iterator is available) - Adds toArrayBuffer to BufferWithRandomAccess (when TypedArray is available) - Adds compileWast(sourceText :string) :ArrayBuffer to the module, parsing & compiling s-expression code to a WASM module - Changes the way binaryen.js is exported to allow usage in CommonJS, AMD and UMD envionments. * Expose "Binaryen" global in a better way to work with a.js generated by check.py * Fix to binaryen.js to only export a global variable when running the test (a.js) while inside a module (avoids polluting global in e.g. nodejs). Also fixes a spelling mistake. * Better "no WASM detected" message in test/binaryen.js/browser.html * Small change to error message in build-js.sh where $EMSCRIPTEN does not point to a directory * Changes emcc args in build-js.sh after investingating a large number of argument combinations. Also adds a browser benchmark. The result of emcc arguments and the effect on performance is summarized in this doc: https://gist.github.com/rsms/e33c61a25a31c08260161a087be03169 * Enable inferring emscripten path by looking in PATH when EMSCRIPTEN is not set in env

* Asm.js-style setjmp/longjmp support for wasm (#681)Heejin Ahn2016-08-261-6/+9
| | | | | | | This needs to export realloc as well, in addition to malloc and free handled in #4469. To support asm.js style setjmp/longjmp, wasm needs to export realloc as well, in addition to malloc and free handled in #4469. saveSetjmp() uses realloc within it, and realloc is not implemented in JS glue code.

| * Fix asm2wasm dead lock caused by empty modules.Logan Chien2016-08-261-1/+9
| | | | | | | | | | | | | | | | | | This commit fixes an asm2wasm dead lock when asm2wasm is compiling an empty module, i.e. a module without any functions. Without this commit, worker threads are likely to leave `workerMain()` and decrease `liveWorkers` early. Consequently, `waitUntilAllReady()` will never observe `liveWorkers == numWorkers`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit modernize the code base by replacing: std::unique_ptr<T>(new T(...)) with: make_unique<T>(...) or: wasm::make_unique<T>(...) This is a step closer to adopt C++14 std::make_unique<T>(...).
* | Fix alignment bug in .lcomm (#680)Heejin Ahn2016-08-261-2/+3
|/ | | | | | | | | | | | When parsing .lcomm directives, s2wasm does not parse the alignment number and skip it. This causes alignment bugs in some cases. (In the test case attached, 'buf' should be 4 bytes aligned, but it does not align it properly, so this code was generated: ``` (call $foo (i32.const 13) ) ``` 13 is not 4-bytes aligned. This patch fixes this bug.

* Implement asm.js style exception handling for Wasm (#664)Heejin Ahn2016-08-112-8/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Implement asm.js style exception handling for Wasm Converts invoke wrapper names generated by LLVM backend to real invoke wrapper names that are expected by JavaScript glue code. This is required to support wasm exception handling (asm.js style). LLVM backend lowers invoke @func(arg1, arg2) to label %invoke.cont unwind label %lpad into ... (some code) call @invoke_SIG(func, arg1, arg2) ... (some code) SIG is a mangled string generated based on the LLVM IR-level function signature. In LLVM IR, types are not lowered yet, so this mangling scheme simply takes LLVM's string representtion of parameter types and concatenate them with '_'. For example, the name of an invoke wrapper for function void foo(struct mystruct*, int) will be "__invoke_void_%struct.mystruct*_int". This function converts the names of invoke wrappers based on their lowered argument types and a return type. In the example above, the resulting new wrapper name becomes "invoke_vii". * Address comments Change variable names to camelcase Add a small (semi-)handwritten test case * Export malloc and free from wasm when available * Add a test case for exporting malloc/free feature + cosmetic 'file' name change in text_before_type.s * fixInvokeWrapper -> fixEmExceptionInvoke * Add a TODO

* Fix a parsing bug introduced by #615 (#661)Heejin Ahn2016-08-051-0/+4
| | | | | | | | | | | | | | | Name lhs = getStrToSep(); if (!skipEqual()){ s = strchr(s, '\n'); if (!s) break; continue; } The above code snippet introduced by #615 has a bug when there is only one word (e.g. ".text") in a line. If there is only one word in a line, skipEqual() also skips the newline character at the end of the line, and strchr(s, '\n') moves the cursor to the end of the next line, effectively skipping the whole next line.
* Create a dummy function to prevent NULL miscomparisons, if necessary (#658)Dominic Chen2016-08-032-16/+49
| | | Resolves WebAssembly/spec#312
* support pre-assigning indexes for functions that are called indirectly (#616)Dominic Chen2016-08-023-2/+38
| | | This patch adds support for an ".indidx" primitive that pre-assigns table indexes for functions that are called indirectly. It is used by the upstream LLVM WebAssembly backend to support fine-grained control-flow integrity for indirect function calls by emitting instrumentation at each indirect call site to check that the destination index is within certain ranges that correspond to disjoint equivalence classes of indirect call targets. The reason that this primitive is necessary is because the layout of the table section isn't determined until the WebAssembly linker is executed, but indirect function to table index mappings need to be known when opt is executed to generate the correct range checking in the LLVM IR.
