closes#2024
there's a new cli option `--main-pkg-path` which you can use to choose
a different root package directory besides the one inferred from the
root source file
and a corresponding build.zig API:
foo.setMainPkgPath(path)
* CLI: `-target [name]` instead of `--target-*` args.
This matches clang's API.
* `builtin.Environ` renamed to `builtin.Abi`
- likewise `builtin.environ` renamed to `builtin.abi`
* stop hiding the concept of sub-arch. closes#1526
* `zig targets` only shows available targets. closes#438
* include all targets in readme, even those that don't
print with `zig targets` but note they are Tier 4
* refactor target.cpp and make the naming conventions
more consistent
* introduce the concept of a "default C ABI" for a given
OS/Arch combo. As a rule of thumb, if the system compiler
is clang or gcc then the default C ABI is the gnu ABI.
New CLI parameter: --c-source [options] [file]
It even works with `--cache on` when there are transitive dependencies.
Instead of `builder.addCExecutable`, use `builder.addExecutable` and pass
`null` for the root source file. Then use `builder.addCSourceFile`,
which takes the path to the C code, and a list of C compiler args.
Be sure to linkSystemLibrary("c") if you want libc headers to be
available.
Merge TestStep into LibExeObjStep. That was long overdue.
* better libc detection
This introduces a new command `zig libc` which prints
the various paths of libc files. It outputs them to stdout
in a simple text file format that it is capable of parsing.
You can use `zig libc libc.txt` to validate a file.
These arguments are gone:
--libc-lib-dir [path] directory where libc crt1.o resides
--libc-static-lib-dir [path] directory where libc crtbegin.o resides
--msvc-lib-dir [path] (windows) directory where vcruntime.lib resides
--kernel32-lib-dir [path] (windows) directory where kernel32.lib resides
Instead we have this argument:
--libc [file] Provide a file which specifies libc paths
This is used to pass a libc text file (which can be generated with
`zig libc`). So it is easier to manage multiple cross compilation
environments.
`--cache on` now works when linking against libc.
`ZigTarget` now has a bool field `is_native`
Better error messaging when you try to link against libc or use
`@cImport` but the various paths cannot be found. It should also be
faster.
* save native_libc.txt in zig-cache
This avoids having to detect libc at runtime on every invocation.
with this change, when you assign undefined, zig emits a few
assembly instructions to tell valgrind that the memory is undefined
it's on by default for debug builds, and disabled otherwise. only
support for linux, darwin, solaris, mingw on x86_64 is currently
implemented.
--disable-valgrind turns it off even in debug mode.
--enable-valgrind turns it on even in release modes.
It's always disabled for compiler_rt.a and builtin.a.
Adds `@import("builtin").valgrind_support` which lets code know
at comptime whether valgrind client requests are enabled.
See #1989
this should actually improve CI times a bit too
See the description at the top of std/os/startup.zig (deleted in this
commit) for a more detailed understanding of what this commit does.
closes#1764
This adds another boolean to the test matrix; hopefully it does not
inflate the time too much.
std.event.Loop does not work with this option yet. See #1908
* add a --system-linker-hack command line parameter to work around
poor LLD macho code. See #1535
* build.zig correctly handles static as well as dynamic dependencies
when building the self hosted compiler.
- no more unnecessary libxml2 dependency
- a static build on macos produces a completely static self-hosted
compiler for macos (except for libSystem as intended).
* introduce --disable-pic option which can generally be allowed to be
the default. compiler_rt.a and builtin.a get this option when you
build a static executable.
* compiler_rt and builtin libraries are not built for build-lib
--static
* posix_spawn instead of fork/execv
* disable the error limit on LLD. Fixes the blank lines printed
This will make it easier to do things like `zig help | grep something`.
Invalid arguments will now display a short notice for `zig help`
instead of showing the full usage information. This will make it easier
to see the actual error.
init-lib creates a working static library with tests, and
init-exe creates a working hello world with a `run` target.
both now have test coverage with the new "cli tests" file.
closes#1035
we need somewhere to put .o files and leave them while the user
executes their program, so that stack traces on MacOS can find
the .o files and get at the DWARF info.
if we try to clean up old global tmp dir files, first of all that's
a hard and complicated problem, and secondly it's not clear how
that is better than dumping the .o file inside zig-cache locally.
* add almost all the input parameter state to the hash
- missing items are the detected MSVC installation on Windows
and detected libc installation on POSIX
- also missing are C files and .h files that libclang finds
* artifacts are created in global cache directory instead of
zig-cache.
- exception: builtin.zig is still in zig-cache
* zig run uses the new cache correctly
* zig run uses execv on posix systems
* introduce std.atomic.Int
* add src-self-hosted/test.zig which is tested by the main test suite
- it fully utilizes the multithreaded async/await event loop so the
tests should Go Fast
* `stage2/bin/zig build-obj test.zig` is able to spit out an error if 2 exported
functions collide
* ability for `zig test` to accept `--object` and `--assembly`
arguments
* std.build: TestStep supports addLibPath and addObjectFile
Support the `--emit` switch in `zig --emit asm test file.zig`.
The command fails because no tests run (no executable is created) but
it emits the requested file. That seems like a good tradeoff.
