The majority of these are in comments, some in doc comments which might
affect the generated documentation, and a few in parameter names -
nothing that should be breaking, however.

* docs(std.math): elaborate on difference between absCast and absInt
* docs(std.rand.Random.weightedIndex): elaborate on likelihood
I think this makes it easier to understand.
* langref: add small reminder
* docs(std.fs.path.extension): brevity
* docs(std.bit_set.StaticBitSet): mention the specific types
* std.debug.TTY: explain what purpose this struct serves
This should also make it clearer that this struct is not supposed to provide unrelated terminal manipulation functionality such as setting the cursor position or something because terminals are complicated and we should keep this struct simple and focused on debugging.
* langref(package listing): brevity
* langref: explain what exactly `threadlocal` causes to happen
* std.array_list: link between swapRemove and orderedRemove
Maybe this can serve as a TLDR and make it easier to decide.
* PrefetchOptions.locality: clarify docs that this is a range
This confused me previously and I thought I can only use either 0 or 3.
* fix typos and more
* std.builtin.CallingConvention: document some CCs
* langref: explain possibly cryptic names
I think it helps knowing what exactly these acronyms (@clz and @ctz) and
abbreviations (@popCount) mean.
* variadic function error: add missing preposition
* std.fmt.format docs: nicely hyphenate
* help menu: say what to optimize for
I think this is slightly more specific than just calling it
"optimizations". These are speed optimizations. I used the word
"performance" here.

All but 3 callsites of this function in the standard library and
compiler were unnecessary and were removed in faf2fd18.
In this commit, the remaining 3 callsites are removed. One of them
turned out to also be unnecessary and has been replaced by slicing
directly with the length..
The 2 remaining callsites were in the very pointer-math heavy
std/os/linux/vdso.zig code which should perhaps be refactored to better
utilize slices. These 2 callsites are replaced with a plain
@ptrCast([*:0]u8, ptr) though could likely use std.mem.sliceTo() if the
surrounding code was refactored.

`register_files_update` was passing a pointer to a Zig struct to the kernel.

Playtime is over. I'm working on networking now.
|
|
There are still a few occurrences of "stage1" in the standard library
and self-hosted compiler source, however, these instances need a bit
more careful inspection to ensure no breakage.
|
|
Returning a bool allows to conveniently use it as the condition
of a while loop.
Also remove restriction that ST cannot be double-word.
While imm is only 32-bit, this value is extended into a 64-bit
memory location.

- the meaning of packed structs changed in zig 0.10. adjust accordingly.
Use "extern struct" for the cases that directly map to C structs.
- Add new type info kinds, like enum64 and DeclTag
- change the Type enum to use the canonical names from libbpf.
This is more predictable when comparing with external BPF
documentation (than invented synonyms that need to be guessed)

|
These are needed because clang doesn't support anything in naked
functions, not even assembly register inputs.
|
|
* Enable advanced start support.
* Enable advanced test_runner support.
* Zig Language Reference's Hello World now works.
|
|
- For ALU operations, src should be allowed to be an explicit Reg.
- Expose AluOp and JmpOp as public types.
This makes code generation using BPF as a backend easier,
as AluOp and JmpOp can be used directly as part of an IR

* io_uring: fix the timeout_remove test
The test does a IORING_OP_TIMEOUT followed with a IORING_OP_TIMEOUT_REMOVE
and assumed we would get the CQEs in the same order.
Linux v5.18 changed how this works and we now get them in the reverse order.
The documentation doesn't explicitly say which CQE we should get first
so just make the test work with both cases.
* io_uring: fix the remove_buffers test
The original test was buggy but accidentally worked with kernels < 5.18
The test assumed that IORING_OP_REMOVE_BUFFERS removed from the start of
but in fact the documentation doesn't specify which buffer is removed,
only that a certain number of buffers are removed.
Starting with the kernel 5.18 the check for the `used_buffer_id` fails.
Turns out that previous kernels removed buffers in such a way that the
remaining buffer for this read would always be 0, however this isn't
true anymore.
Instead of checking a specific value just check that the `used_buffer_id`
corresponds to a valid ID.

alongside the typical msghdr struct, Zig has added a msghdr_const
type that can be used with sendmsg which allows const data to
be provided. I believe that data pointed to by the iov and control
fields in msghdr are also left unmodified, in which case they can
be marked const as well.

readv() is essentially identical to read() except for the buffer type,
this simplifies the API for the caller at the cost of not clearly mapping to the liburing C API.
|
|
|
|
|
|
|
|
RecvBuffer is equivalent to ReadBuffer but tailored for recv only.
|
|
Reads can be done in two ways with io_uring:
* using a simple buffer
* using a automatic buffer selection which requires the user to have
provided a number of buffers before
ReadBuffer let's the caller choose where the data should be read.
|
|
These functions are needed to implement automatic buffer selection.
This maps to the IORING_OP_PROVIDE_BUFFERS and IORING_OP_PROVIDE_BUFFERS ops.

Previously, updating the `SYS` enum for each architecture required
manually looking at the syscall tables and inserting any new additions.
This commit adds a tool, `generate_linux_syscalls.zig`, that automates
this process using the syscall tables in the Linux source tree. On
architectures without a table, it runs `zig cc` as a pre-processor to
extract the system-call numbers from the Linux headers.

Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.
