Justification: exec, execv etc are unix concepts and portable version
should be called differently.
Do no touch non-Zig code. Adjust error names as well, if associated.
Closes#5853.
Introduce introspect.EnvVar which tracks all the environment variables
that are observed by the compiler, so that we can print them with `zig
env`.
The `zig env` command now prints both the resolved values as well as all
the possibly observed environment variables.
- Adds `illumos` to the `Target.Os.Tag` enum. A new function,
`isSolarish` has been added that returns true if the tag is either
Solaris or Illumos. This matches the naming convention found in Rust's
`libc` crate[1].
- Add the tag wherever `.solaris` is being checked against.
- Check for the C pre-processor macro `__illumos__` in CMake to set the
proper target tuple. Illumos distros patch their compilers to have
this in the "built-in" set (verified with `echo | cc -dM -E -`).
Alternatively you could check the output of `uname -o`.
Right now, both Solaris and Illumos import from `c/solaris.zig`. In the
future it may be worth putting the shared ABI bits in a base file, and
mixing that in with specific `c/solaris.zig`/`c/illumos.zig` files.

`std.zig.system.darwin.getSdk` now pulls only the SDK path
so we execute a child process only once and not twice as it was
until now since we parse the SDK version directly from the pulled path.
This is actually how `ld64` does it too.
Regressed in 2006add8496c47804ee3b6c562f420871cb4ea0a.
References to native_darwin_sdk are no longer kept in the frontend.
Instead the darwin SDK is detected as part of NativePaths and as part of
LibCInstallation.
Reverts 4fa8cc736966544da381c90a6111158179fc550b. This check was added
because it depended on C++ code, but after
77b96231a6bc195cc482d05599e8c20ee01645a6, this functionality no longer
depends on C++ code.
This commit removes the tiny amount of dependency on async/await that
the self-hosted compiler has so that it can self-host before async/await
language features are working.
In accordance with the requesting issue (#10750):
- `zig test` skips any tests that it cannot spawn, returning success
- `zig run` and `zig build` exit with failure, reporting the command the cannot be run
- `zig clang`, `zig ar`, etc. already punt directly to the appropriate clang/lld main(), even before this change
- Native `libc` Detection is not supported
Additionally, `exec()` and related Builder functions error at run-time, reporting the command that cannot be run
Zig has detection for when it is accidentally being called recursively
when trying to find the native libc installation. However it was not
working, resulting in a cryptic failure, because zig tried to execute
a command which had spaces in it rather than tokenizing it.
This improves the user experience of `zig cc` for systems that Zig
does not support cross-compiling for.
Closes#8960
- hash/eql functions moved into a Context object
- *Context functions pass an explicit context
- *Adapted functions pass specialized keys and contexts
- new getPtr() function returns a pointer to value
- remove functions renamed to fetchRemove
- new remove functions return bool
- removeAssertDiscard deleted, use assert(remove(...)) instead
- Keys and values are stored in separate arrays
- Entry is now {*K, *V}, the new KV is {K, V}
- BufSet/BufMap functions renamed to match other set/map types
- fixed iterating-while-modifying bug in src/link/C.zig
* for some reason part of the linkable bits for the crt libraries
are split in different locations for haiku. this changeset
accomodates this situation (crtbegin_dir lookup)
- more support for linux, android, freebsd, netbsd, openbsd, dragonfly
- centralize musl utils; musl logic is no longer intertwined with csu
- fix musl compilation to build crti/crtn for full archs list
- fix openbsd to support `zig build-lib -dynamic`
- initial dragonfly linking success (with a warning)
ancillary:
- fix emutls (openbsd) tests to use `try`
