* Let cmake add "-g" flag when it is needed (#1576)Praveer Kumar2020-12-011-2/+1
|
* wasm2c: build library wasm-rt-impl (#1408)Edmund Wu2020-10-231-0/+7
| | | Also include header files needed for compilation
* fix compile failed on Ubuntu 18.04 aarch64 cmake3.10.2 (#1559)Xingqang Bai2020-10-211-0/+4
|
* Enable -Werror during CI (#1522)Sam Clegg2020-08-181-9/+7
| | | | Fixes: #1249
* Enable multi-core build on Windows (#1516)Wouter van Oortmerssen2020-08-101-0/+4
| | | This speeds up builds of WABT significantly
* Add tools to use LLVM's libFuzzer (#1507)Ben Smith2020-08-031-5/+34
| | | | This is useful for reproducing bugs found by oss-fuzz (see https://bugs.chromium.org/p/oss-fuzz/issues/list?q=wabt)
* Enable CMake policy CMP0077 (#1471)Steven Johnson2020-06-191-0/+4
| | | | | TL;DR: this makes it simpler and safer for projects including WABT via FetchContent to configure options via the CMAKE_ARGS argument. Importing projects may want to set (e.g.) BUILD_TESTS to "no". However, this doesn't work without creating an identical option() in the importing in the importing project. Enabling CMP0077 in supported versions of CMake allows importing projects to set default values for the variables without touching the cache.
* Update libwabt.js; fix some runtime issues (#1468)Ben Smith2020-06-181-7/+13
| | | | | | | libwabt.js is meant to be included in multiple environments (web, node.js, etc.) so it shouldn't be using NODERAWFS. A recent change to the build system include `-s NODERAWFS` for all link steps, but those are only needed for the wabt executables (e.g. wasm2wast.js).
* Improve CMakeLists.txt for when used via add_subdirectory() (#1467)Steven Johnson2020-06-181-2/+14
|
* Allow building all tools with emscripten (#1436)Alon Zakai2020-05-211-242/+248
| | | | | | | | | This allows building say wasm2c.js, and not just wabt.js. (99% of this is a change to indentation) Also remove --llvm-lto 1 which is a no-op with the upstream backend anyhow (however, to get LTO we'd need to build sources with -flto).
* Add build flag to disable build of libwasm (#1435)Derek Schuff2020-05-191-9/+12
| | | This allows the wabt tools to be build with no git submodules
* Implement more WASI APIs (#1423)Sam Clegg2020-05-161-1/+0
| | | | This is almost enough to pass all the tiny tests in the wasi-sdk repo.
* Add initial MVP of WASI API support to wasm-interp (#1411)Sam Clegg2020-05-121-1/+15
| | | | | | | | | | This is proof of concept that only implements the `proc_exit` and `fd_write` APIs. Extending this to the full WASI API will to follow assuming this approach seems reasonable. Fixes #1409
* Improve error message when python 3 not available - Fix for #1385 (#1392)lkarthee2020-04-271-2/+7
| | | | | | | | | * making python optional for build. https://github.com/WebAssembly/wabt/issues/1385 * Show error message about skipping tests if python3 is not available * Skipping tests when Python 3.5 or above is not found.
* Set -D_POSIX_C_SOURCE for MINGW/CYGWIN only (#1360)Raphael Graf2020-03-151-3/+5
| | | Resolves #1359
* Share validator between IR + binary-reader-interp (#1346)Ben Smith2020-02-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The TypeChecker was already shared, but the rest of the other validation logic was duplicated. This change creates a SharedValidator which is used by both the Validator and the BinaryReaderInterp classes. The validator is structured similarly to TypeChecker as a collection of functions. It's assumed that the functions will be called in the same order as sections occur in the binary format. The IR valiator does this too, even though it's possible to validate components out-of-order in that case. This change also splits Module validation and Script validation into two different classes. It should have been written this way in the first place, and it's nice to do as part of this change since the module validator logic is mostly moved into the SharedValidator anyway. Next steps: * Remove all validation from BinaryReader and move it into the SharedValidator. * Move the TypeChecker into the SharedValidator (maybe not necessary) * Ensure that validation occurs before creating IR from binary (use SharedValidator in BinaryReaderIR? or maybe create BinaryReaderValidator passthru that both BinaryReaderIR and BinaryReaderInterp use?) * Rename Validator -> IRValidator, SharedValidator -> Validator
* Move the Type enum to its own file (#1344)Ben Smith2020-02-261-0/+1
| | | This is a good start to cleaning up common.h.
* New interpreter (#1330)Ben Smith2020-02-211-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's modeled closely on the wasm-c-api. All runtime objects are garbage-collected. The GC'd objects are subclasses of `Object` and all stored in the `Store`. GC roots can be created using a RefPtr<T> struct. The `Module` stores no runtime objects, only description structs (named `*Desc`, e.g. `FuncDesc`). Instantiation takes these descriptors and turns them into runtime objects (e.g. `FuncDesc` is used to create a `Func`). Only import-matching occurs during instantiation; all other validation is assumed to have occurred during Module compilation. As with the previous interpreter, the wasm instructions are not executed directly, and instead compiled to an instruction stream that is easier to interpret (e.g. all branches become gotos). It's still a stack machine, though. The previous interpreter would always compile and instantiate in one step, which means that it was always known whether an imported function is a host function or wasm function. As a result, calls between modules that stayed in wasm could be very cheap (just update PC). Now that the module is compiled before instantiation, an imported function call always has to check first, which may be a slight performance hit. One major difference to the structure of the interpreter is that floating-point values are passed directly, instead of using their equivalent bit pattern. This is more convenient in general, but requires annotating all functions with WABT_VECTORCALL so Visual Studio x86 works properly (otherwise floats are passed in the x87 FP stack). Instruction stream decoding/tracing/disassembling is now all handled in the `Istream` class. This reduces a lot of duplication between the three, which makes the logging-all-opcodes and tracing-all-opcodes less valuable, so I've removed them. Here are the changes to files: binary-reader-metadata.{h,cc} -> [removed] interp-{disassemble.trace}.cc -> istream.{h,cc} There are new helper files: interp-util.{h,cc}: Primarily print debugging functions interp-math.h: Templates used for handling wasm math
* Use standard C++11 on GNU/Clang compilers (#1333)okuoku2020-02-181-15/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Use _POSIX_C_SOURCE where applicable Use _POSIX_C_SOURCE=200809L everywhere except MSVC. For MinGW, it should have same effect in regard of `__USE_MINGW_ANSI_STDIO`. For Cygwin, it will allow to use POSIX APIs under `-std=c++11` environment. * binary-reader-objdump.cc: #include <strings.h> Include `strings.h` because it depends POSIX strcasecmp. * Disable `CMAKE_CXX_EXTENSIONS` explicitly Explicitly disable `CMAKE_CXX_EXTENSIONS` which is ON by default in recent CMake(>= 3.1) which will read implicit `-std=gnu++11` injection. * test-hexfloat: Use <thread> instead of sysconf Use <thread> instead of sysconf which is a bit more "standard" way to do this. * Guard <strings.h> with HAVE_STRCASECMP Guard `strings.h` with `HAVE_STRCASECMP` because non-POSIX platform may not have it.
* Cygwin build fixes (#1332)okuoku2020-02-111-1/+9
| | | | | | | | | | | | | | | * Workaround for Cygwin build On cygwin, `__STRICT_ANSI__` does not show POSIX definitions. Use gnu++11 language instead. * wasm-decompile: Silence -Wsign-compare Silence -Wsign-compare warning, by using unsigned literal one. * wasm-objdump: Fix 4294967296 output on disasm Use `%u` instead of `%lu` as we use `uint32_t` here.
* Remove support for python2 (#1321)Sam Clegg2020-01-311-7/+2
|
* Include `CMakeParseArguments` (#1310)Ben Smith2020-01-311-0/+1
| | | Fixes #1042, thanks @rathann!
* Remove build-time dependency on git (#1316)Sam Clegg2020-01-231-18/+19
| | | | | | Add VERSION to project command, which in turn required a cmake version bump to 3.0.0. Fixes: #1314
* Put rendered man page html in docs, not .1 filesBen Smith2020-01-171-1/+1
|
* Move documentation to docs/ directoryBen Smith2020-01-171-1/+1
| | | | It's easier to update than gh-pages
* Initial WASM C API implementation. (#1250)Sam Clegg2020-01-161-2/+60
| | | | All tests except `threads` pass.
* Add CMAKE_EXPORT_COMPILE_COMMANDS to CMakeLists.txt (#1208)Sam Clegg2020-01-151-0/+2
| | | | This allows code completion tools such as clangd to work. I'm not sure if there is any downside to enabling this in all cases?
* wasm-decompile: overhauled name filtering. (#1272)Wouter van Oortmerssen2019-12-231-0/+1
| | | | | | | The previous implementation was too simplistic, as it didn't do the renaming at the correct location (such that it can catch all occurrences), and was also very ineffective in cutting down gigantic STL signatures to something managable. This version creates more usable identifiers in almost all cases.
* wasm-decompile: Load/Store tracking for struct output. (#1258)Wouter van Oortmerssen2019-12-091-1/+2
| | | | | | | This tries to make code more readable by summarizing patterns of load/store ops into "struct" declarations. Initial version, can probably be improved, but has all essentials of the idea in place.
* Split run-unittests out as seperate target (#1255)Sam Clegg2019-12-031-12/+18
| | | | | | | | | | | | | | New `check` target now runs other. This allows for github actions to show unittests and system tests as separate steps. Also a couple of CMakeLists.txt cleanups: - Don't use add_definition to add `-fno-exceptions`, this is a C++-only flag. - Lowercase the name of the `sanitizer` function. - Remove opcode.def from list of library input file. On windows when building a DLL .def files are assumed to be windows DLL .def files, which this is not. This change is split out from #1250
* Initial support for github actions (#1238)Sam Clegg2019-11-221-1/+7
| | | | | | | | | | | | This adds a basic workflow that builds and tests wabt on all three desktop platforms. The plan is to extend this to completely replace travis and appveyor in the future. Remove the 2.7 requirement for python in CMakeLists.txt due to issue with github actions where this ends up selected in the wrong (mingw) version of python. See: https://github.com/actions/setup-python/issues/40
* Fix run-tests target on windows (#1247)Sam Clegg2019-11-221-2/+2
| | | | | | | Under windows binaries end with `.exe` and live a the `Debug` or `Release` subdirectory so we need to use $<TARGET_FILE> to get the full executable name.
* Fix for failing `git describe` in CMakeLists.txt (#1234)Sam Clegg2019-11-191-3/+3
|
* Check for MSVC first in list of compiler tests (#1209)Derek Schuff2019-11-061-5/+5
| | | | | | This allows use of clang-cl.exe, wherin Clang pretends to be MSVC and accepts its flags. It will be treated as MSVC in this case. There are a few places where we'll want to tune further, and perhaps refactor to allow a compiler to be both MSVC and clang, or perhaps use clang's flags instead of MSVC's. But this gets things working.
* wasm-decompile: Added initial tests. (#1195)Wouter van Oortmerssen2019-10-241-9/+6
| | | These are pretty minimal, more will be added as part of feature-PRs.
* wasm-decompile: Refactored code to first build an AST. (#1191)Wouter van Oortmerssen2019-10-181-0/+1
| | | | This will pave the way for a better multi-pass analysis that can collect information for the final output pass.
* Add `--version` to wabt tools (#1175)Amir Bawab2019-10-091-0/+16
| | | | | | | | | | | | | Closes: #1106 Ported versioning system from [Binaryen CMakeLists.txt](https://github.com/WebAssembly/binaryen/blob/dc31b460fef47dfb3415b4ae6276fff4919a03e2/CMakeLists.txt#L10-L23) ``` bin/wasm2c --version 1.0.11-44-g71f883ad ``` Applied to (all) tools in `src/tools/`.
* Add wabt-unittests as dependency of run-tests (#1157)Ben Smith2019-09-251-0/+1
| | | | | Without this, running `make test` will fail. Fixes issue #1149.
* [WIP] Added initial skeleton code for wasm-decompile. (#1155)Wouter van Oortmerssen2019-09-121-0/+53
| | | | | | * [WIP] Added initial skeleton code for wasm-decompile. * Code review changes.
