Ayke van Laethem	c522569378	wasm: only export explicitly exported functions Previously we used the --export-all linker flag to export most functions. However, this is not needed and possibly increases binary size. Instead, we should be exporting the specific functions to be exported.	4 years ago
Ayke van Laethem	869baca117	wasi: specify wasi-libc in a different way This way is more consistent with how picolibc is specified and allows generating a helpful error message. This error message should never be generated for TinyGo binary releases, only when doing local development.	4 years ago
Takeshi Yoneda	9a015f4f64	add wasm-abi field in TargetSpec && set generic for WASI by default (#1421 ) Signed-off-by: mathetake <takeshi@tetrate.io>	4 years ago
Elliott Sales de Andrade	32c7f3baf9	Remove --no-threads from wasm-ld calls. The bugs linked from the original addition of this flag are fixed: https://bugs.llvm.org/show_bug.cgi?id=41508 or 'possibly fixed': https://bugs.llvm.org/show_bug.cgi?id=37064#c8 since LLVM 8.0.1. TinyGo only support LLVM 9+, and as noted in the original PR (#377), this can be removed when switching to 9. Additionally, this flag was dropped from LLVM 11.	4 years ago
Hiroki Noda	c9fc95f6f3	wasm32: Add --no-demangle option LLD supports only C++ demangle, so disable it.	4 years ago
Ayke van Laethem	e2aa3789c3	wasm: include wasi-libc This allows CGo code to call some libc functions. Additionally, by putting memset/memmove/memcpy in an archive they're not included anymore when not necessary, reducing code size for small programs.	5 years ago
Ayke van Laethem	00cc486619	wasm: set the stack at the start of linear memory This makes sure that a stack overflow will cause a "memory access out of bounds" error instead of a corruption of a global variable. Here is more background on a very similar stack overflow protection: https://blog.japaric.io/stack-overflow-protection/	5 years ago
Ayke van Laethem	f7687c43aa	wasm: fix wasm-ld hang See the following bugs for more information: https://bugs.llvm.org/show_bug.cgi?id=41508 https://bugs.llvm.org/show_bug.cgi?id=37064	6 years ago
Ayke van Laethem	1d59a960bc	main: allow changing the clang command name	6 years ago
Ayke van Laethem	2f2d62cc0c	cgo: support builtin #include headers Add support for header files bundled with the compiler by copying them into the release tarball.	6 years ago
Ayke van Laethem	31d57fd3d1	main: use wasm-ld instead of wasm-ld-8 on macOS This commit does a few things: * remove the -8 suffix on macOS, where it is not necessary * add smoke tests for compiling wasm files on Linux and macOS	6 years ago
Ayke van Laethem	9c41011e17	all: switch to LLVM 8	6 years ago
Ayke van Laethem	41e093d7bb	wasm: switch emulator to node.js Unfortunately, the olin/cwa emulator does not handle floats correctly. Node.js does, and because it is also supported by the Go WebAssembly implementation it has better support in general.	6 years ago
Ayke van Laethem	25cd982263	main: optionally build with LLD When building statically against LLVM, LLD is also included now. When included, the built in wasm-ld will automatically be used instead of the external command. There is also support for linking ELF files but because lld does not fully support armv6m this is not yet enabled (it produces a warning).	6 years ago
Ayke van Laethem	072ef603fe	wasm: add GOOS/GOARCH properties This was an oversight in commit `107fccb288`.	6 years ago
Ayke van Laethem	8ee3267260	wasm: compile .c files in packages	6 years ago
Ayke van Laethem	e101937589	wasm: fix .json file after compiler updates	6 years ago
Ayke van Laethem	b09b07a52d	wasm: allow all undefined symbols Undefined symbols will be shown by the embedder, for example when running generated wasm files in a browser. In the future, this should probably become a fixed list again. But for experimenting it's easier now to just ignore undefined symbols and expect the JS to provide them.	6 years ago
Ayke van Laethem	e5e09747f0	all: add WebAssembly backend	6 years ago
