These are tripping on 32-bit x86 but are intended to prevent glibc
itself from being built with a bad configuration. Zig is only using this
file to create libc_nonshared.a, so it's not relevant.
This is the only place in all of glibc that this macro is referenced.
What is it doing? Only preventing fstatat.c from knowing the type
definition of `__time64_t`, apparently.
Fixes compilation of fstatat.c on 32-bit x86.
I could have just included the file from upstream glibc, but it was too
silly so I just inlined it. This patch could be dropped in a future
glibc update if desired. If omitted it will cause easily solvable
C compilation failures building glibc nonshared.
- `fcntl` was renamed to `fcntl64` in glibc 2.28 (see #9485)
- `res_{,n}{search,query,querydomain}` became "their own" symbols since
glibc 2.34: they were prefixed with `__` before.
This PR makes it possible to use `fcntl` with glibc 2.27 or older and
the `res_*` functions with glibc 2.33 or older.
These patches will become redundant with universal-headers and can be
dropped. But we have to do with what we have now.
This is a patch to glibc features.h which makes
_DYNAMIC_STACK_SIZE_SOURCE undefined unless the version is >= 2.34.
This feature was introduced with glibc 2.34 and without this patch, code
built against these headers but then run on an older glibc will end up
making a call to sysconf() that returns -1 for the value of SIGSTKSZ
and MINSIGSTKSZ.
SPARCs have delayed branches, that is, it will unconditionally
run the next instruction following a branch.
Slightly reorder the _start code sequence to prevent it from
accidentally executing stray instructions, which may result in odd
program behavior.
`ContainerDeclarations` is an abstraction of `ContainerDeclaration*`.
Removing this abstraction allows the `ContainerMembers` rule to contain
more concrete information without having to look at the definition
of `ContainerDeclarations`.
When `std.mem.indexOf` is called with a single-item needle, use `indexOfScalarPos` which is significantly faster than the more general `indexOfPosLinear`. This can be done without introducing overhead to normal cases (where `needle.len > 1`).
* fs/test.zig: use arena allocator more consistently
* fs/test.zig: remove unnecessary type information
Zig can (now?) implicitly cast a `&.{ "foo"}` when passed to
`fs.path.join()`, so the `[_][]const u8` is unnecessary.
* fs/test.zig: Use fs.path.join() for longer paths
Replace long path constructions (that use several "++ path_sep ++")
with a single call to `fs.path.join`. Seems more readable to me.
* fs/test.zig: fmt
* add Module instances for each package's build.zig and attach it to the
dependencies.zig module with the hash digest hex string as the name.
* fix incorrectly skipping the wrong packages for creating
dependencies.zig
* a couple more renaming of "package" to "module"
Finish the work started in 4c4fb839972f66f55aa44fc0aca5f80b0608c731.
Now the compiler compiles again.
Wire up dependency tree fetching code in the CLI for `zig build`.
Everything is hooked up except for `createDependenciesModule` is not yet
implemented.
* start renaming "package" to "module" (see #14307)
- build system gains `main_mod_path` and `main_pkg_path` is still
there but it is deprecated.
* eliminate the object-oriented memory management style of what was
previously `*Package`. Now it is `*Package.Module` and all pointers
point to externally managed memory.
* fixes to get the new Fetch.zig code working. The previous commit was
work-in-progress. There are still two commented out code paths, the
one that leads to `Compilation.create` and the one for `zig build`
that fetches the entire dependency tree and creates the required
modules for the build runner.
Originally inspired by Go's `utf8.Valid` function. Includes some test cases from Go's test suite.
Further optimized to be faster in all tested cases (short/long ascii/UTF8), in all release modes.
Takes advantage of SIMD for the ASCII fast path.
