Not all of the softfloat library is being built....
Vector support is very buggy at the moment, but should work when the bugs are fixed.
(as I had the same code working with another vector function, that hasn't been merged yet).
* introduce wasm32-freestanding-musl .h files to fix
conflicts with stddef.h and errno.h
* fix an issue with zig build system regarding installation of
webassembly libraries
* add implementations to zig's libc:
- strcmp
- strncmp
- strerror
- strlen
See #514
- wip for #2046
- clang .d output must be created with `clang -MV` switch
- implemented in Zig
- hybridized for zig stage0 and stage1
- zig test src-self-hosted/dep_tokenizer.zig
* rename std/special/builtin.zig to std/special/c.zig
not to be confused with @import("builtin") which is entirely
different, this is zig's multi-target libc implementation.
* WebAssembly: build-exe is for executables which have a main().
build-lib is for building libraries of functions to use from,
for example, a web browser environment.
- for now pass --export-all for libraries when there are any
C objects because we have no way to detect the list of exports
when compiling C code.
- stop passing --no-entry for executables. if you want --no-entry
then use build-lib.
* make the "musl" ABI the default ABI for wasm32-freestanding.
* zig provides libc for wasm32-freestanding-musl.
Previously, `zig fmt` on the stage1 compiler (which is what we currently
ship) would perform what equates to `zig run std/special/fmt_runner.zig`
Now, `zig fmt` is implemented with the hybrid zig/C++ strategy outlined
by #1964.
This means Zig no longer has to ship some of the stage2 .zig files, and
there is no longer a delay when running `zig fmt` for the first time.
On macOS building with Xcode/clang the linker complains loudly when
symbol visibility is inconsistent. This option syncs visibilty setting
of both LLVM and Zig.
Previously libuserland was being built for the native target,
which could depend on native CPU features such as AVX. The
CI infrastructure is intending to create binaries that are
widely compatible and do not make use of specific CPU features.
There could be something to gain from enabling native CPU features
sometimes, by introducing a new cmake configuration option, but
since it's planned to eventually ship self-hosted rather than stage1,
I don't think it really matters.
