Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`
The old vectorization helper (WipElementWise) was clunky and a bit
annoying to use, and it wasn't really flexible enough.
This introduces a new vectorization helper, which uses Temporary and
Operation types to deduce a Vectorization to perform the operation
in a reasonably efficient manner. It removes the outer loop
required by WipElementWise so that implementations of AIR instructions
are cleaner. This helps with sanity when we start to introduce support
for composite integers.
airShift, convertToDirect, convertToIndirect, and normalize are initially
implemented using this new method.
Besides the Intel OpenCL CPU runtime, we can now run the
behavior tests using the Portable Computing Language. This
implementation is open-source, so it will be easier for us
to patch in updated versions of spirv-llvm-translator that
have bug fixes etc.
* Skip building libcxx mt-only source files when single-threaded.
* This change is required for llvm18 libcxx.
* Add standalone test to link a trivial:
- mt-executable with libcxx
- st-executable with libcxx
Had constrained the `aarch64_be` target, but not `aarch64`. This
constraint is necessary because earlier versions of glibc do not support
the aarch64 architecture.
Also, skip unsupported test cases.
glibc_runtime_check.c is a simple test case that exercises glibc functions
that might smoke out linking problems with Zig's C compiler. The
build.zig compiles it against a variety of glibc versions.
Also document and test glibc v2.2.5 (from 2002) as the oldest working
glibc target for C binaries.
Instead of introducing YES_COLOR, a completely new standard, into the mix
it might make more sense to instead tag along with the CLICOLOR_FORCE env var,
which dates back to at least 2000 with FreeBSD 4.1.1 and which is
supported by tools like CMake.

Introduces `disable_zig_progress` which prevents the build runner from
assigning the child process a progress node.
This is needed for the empty_env test which requires the environment to
be completely empty.
You don't know if it's possible to run a binary until you try. The build
system already integrates with executors and has the
`skip_foreign_checks` for exactly this use case.
This reverts commit a7de02e052.
This did not implement the accepted proposal, and I did not sign off
on the changes. I would like a chance to review this, please.
Fixes regression introduced by 5d5e89aa8d
Turns out since landing that PR we haven't run any tests requiring
symlinks or any Apple SDK on a macOS host. Not great.
Previously the error had a note suggesting to use `try`, `catch`, or
`if`, even for error sets where none of those work.
Instead, in case of an error set the way you can handle the error
depends very much on the specific case. For example you might be in a
`catch` where you are discarding or ignoring the error set capture
value, in which case one way to handle the error might be to `return`
the error.
So, in that case, we do not attach that error note.
Additionally, this makes the error tell you what kind of an error it is:
is it an error set or an error union? This distinction is very relevant
in how to handle the error.
Maybe I'm just being pedantic here (most likely) but I don't like how we're
just telling the user here how to "suppress this error" by "assigning the value to '_'".
I think it's better if we use the word "discard" here which I think is
the official terminology and also tells the user what it actually means
to "assign the value to '_'".
Also, using the value would also be a way to "suppress the error".
It is just one of the two options: discard or use.
this one is even harder to document then the last large overhaul.
TLDR;
- split apart Emit.zig into an Emit.zig and a Lower.zig
- created seperate files for the encoding, and now adding a new instruction
is as simple as just adding it to a couple of switch statements and providing the encoding.
- relocs are handled in a more sane maner, and we have a clear defining boundary between
lea_symbol and load_symbol now.
- a lot of different abstractions for things like the stack, memory, registers, and others.
- we're using x86_64's FrameIndex now, which simplifies a lot of the tougher design process.
- a lot more that I don't have the energy to document. at this point, just read the commit itself :p
