tidy gives a false positive:
line 304 column 9 - Warning: moved <style> tag to <head>! fix-style-tags: no to avoid.
I noticed that `--show-warnings no` still incorrectly causes exit code 1.
I was unable to find an alternative to tidy.
There was already `zig build test-fmt` but now `zig build test` depends
on that one.
The CI scripts no longer need explicit logic since they already do
`zig build test`.
Now there is `captureChildProcess` which gives access to the
`std.process.Child.RunResult`, which is useful for accessing the stdout.
It also accepts and passes an optional `std.Progress.Node` to the child.
There were two primary issues at play here:
1. The hex float prefix was not handled correctly when the stream was
reset for the fallback parsing path, which occured when the mantissa was
longer max mantissa digits.
2. The implied exponent was not adjusted for hex-floats in this branch.
Additionally, some of the float parsing routines have been condensed, making
use of comptime.

Before this commit, the DIRECTORY_NOT_EMPTY/FILE_IS_A_DIRECTORY/NOT_A_DIRECTORY statuses were assumed only to be possible when using `FILE_RENAME_INFORMATION_EX` and `FILE_RENAME_POSIX_SEMANTICS`, but that has empirically been shown to be false; a networked samba share can return the DIRECTORY_NOT_EMPTY status from `FILE_RENAME_INFORMATION` (which doesn't support `FILE_RENAME_POSIX_SEMANTICS`).
`FILE_IS_A_DIRECTORY` and `NOT_A_DIRECTORY` were not proven to be possible, but they were also moved to the outer switch just in case.

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 doc comments for this global said:
"Locked to avoid interleaving panic messages from multiple threads."
Huh? There's already a mutex for that, it's the stderr mutex. Lock that
one instead.
The surrogate code points U+D800 to U+DFFF are valid code points but are not Unicode scalar values. This commit makes the error message more accurately reflect what is actually allowed in `\u` escape sequences.
From https://www.unicode.org/versions/Unicode15.0.0/ch03.pdf:
> D71 High-surrogate code point: A Unicode code point in the range U+D800 to U+DBFF.
> D73 Low-surrogate code point: A Unicode code point in the range U+DC00 to U+DFFF.
>
> 3.9 Unicode Encoding Forms
> D76 Unicode scalar value: Any Unicode code point except high-surrogate and low-surrogate code points.

A node may be freed during the execution of this loop, causing there to
be a parent reference to a nonexistent node. Without this assignment,
this would lead to the map entry containing stale data. By assigning
none, the child node with the bad parent pointer will be harmlessly
omitted from the tree.
Closes#20262
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.
Previously the child type of a vector was always in indirect representation.
Concretely, this meant that vectors of bools are represented by vectors
of u8.
This was undesirable because it introduced a difference between vectorizable
operations with a scalar bool and a vector of bool. This commit changes the
representation to be the same for vectors and scalars everywhere.
Some issues arised with constructing vectors: it seems the previous temporary-
and-pointer approach does not work properly with vectors of bool. To work around
this, simply use OpCompositeConstruct. This is the proper instruction for this,
but it was previously not used because of a now-solved limitation in the
SPIRV-LLVM-Translator. It was not yet applied to Zig because the Intel OpenCL
CPU runtime does not have a recent enough version of the translator yet, but
to solve that we just switch to testing with POCL instead.
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.
These instructions are not emitted by AstGen. They also would have no
effect even if they did appear in ZIR: the Sema handling for these
instructions creates a Decl which the name strategy is applied to, and
proceeds to never use it. This pointless CPU heater is now gone, saving
2 ZIR tags in the process.
`Elf*_Rela` relocations store their argument in `r_addend`, including for `R_*_RELATIVE` relocations. Unlike `Elf*_Rel` relocations, they are not applied as a delta to the destination virtual address. Instead, they are computed from `base_address + r_addend` directly.
We are posting two submission (zero copy send and receive) and then
reading two completions. There is no guarantee that those completions
will be in the order of submissions.
This test was expecting fist send completion then receive.
Fix is allowing them to come other way too.
* 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
