- Fix usage string `--skip-code-test` to `--skip-code-tests`.
- Added a token `{#additonal_option|-rdynamic#}` which introduce arbitrary flag to `build-exe/obj/lib` example.
- Fix wasm freestanding example, it now needs explicit export symbols to work.
* @workItemId returns the index of the work item in a work group for a
dimension.
* @workGroupId returns the index of the work group in the kernel dispatch for a
dimension.
* @workGroupSize returns the size of the work group for a dimension.
These builtins are mainly useful for GPU backends. They are currently only
implemented for the AMDGCN LLVM backend.
This should add all remaining missing return types to all builtin
functions.
For @clz, @ctz, and @popCount it uses anytype for the lack of a better
alternative. We already use this return type for other builtin functions in the langref
to indicate that the type is not always the same.
It is not possible to use anytype as the return type for regular
functions but builtin functions are special.
In 41 (Undefined Behavior) . 5 (Integer Overflow) . 3 (Builtin Overflow Functions), it is stated that
> These builtins return a bool of whether or not overflow occurred, as well as returning the overflowed bits:
> * @addWithOverflow
> * @subWithOverflow
> * @mulWithOverflow
> * @shlWithOverflow
but in their definition says that it returns a `tuple`/`struct`.
Example;
`@addWithOverflow(a: anytype, b: anytype) struct { @TypeOf(a, b), u1 }`

This introduces a new builtin function that compiles down to something that results in an illegal instruction exception/interrupt.
It can be used to exit a program abnormally.
This implements the builtin for all backends.
* Scan from line start when finding tag in tokenizer
This resolves a crash that can occur for invalid bytes like carriage
returns that are valid characters when not parsed from within literals.
There are potentially other edge cases this could resolve as well, as
the calling code for this function didn't account for any potential
'pending_invalid_tokens' that could be queued up by the tokenizer from
within another state.
* Fix carriage return crash in multiline string
Follow the guidance of #38:
> However CR directly before NL is interpreted as only a newline and not part of the multiline string. zig fmt will delete the CR.
Zig fmt already had code for deleting carriage returns, but would still
crash - now it no longer does so. Carriage returns encountered before
line-feeds are now appropriately removed on program compilation as well.
* Only accept carriage returns before line feeds
Previous commit was much less strict about this, this more closely
matches the desired spec of only allow CR characters in a CRLF pair, but
not otherwise.
* Fix CR being rejected when used as whitespace
Missed this comment from ziglang/zig-spec#83:
> CR used as whitespace, whether directly preceding NL or stray, is still unambiguously whitespace. It is accepted by the grammar and replaced by the canonical whitespace by zig fmt.
* Add tests for carriage return handling
Some examples using {#syntax_block|zig|...#} either have a valid syntax
or it is easy to make the syntax valid. Update these example to use
{#code_begin|syntax|...#}.
Remove extra whitespace in the error_union_parsing_u64.zig example.
Replace size_t with usize in the call_malloc_from_zig.zig example.
Commit 40f5e5dfc6 ("CLI: introduce -fsingle-threaded/
-fno-single-threaded", 2021-12-01) removed the `--single-threaded`
option, but didn't update all mentions of it.

PR #10610 addressed most of the points from #1854. This
additional paragraph and examples covers the OMISSIONS section
clarifying issues about indexing into non-ASCII strings (whether valid
UTF-8 or not). I think this finally closes#1854.
In the "Type Coercion" section, rename:
- Coercion Float to Int => Float to Int
- unions and enums => Unions and Enums
- tuples to arrays => Tuples to Arrays
In the "C Translation CLI" section, move the paragraph inside the p
element.
The current HTML is valid, but, as an example, a paragraph outside a p
element is not handled correctly by the browser Inspect tool.
In commit 3542dbf0ea (langref: add section numbers) I accidentally
added an extra closing curly bracket at the end of the style element.
Sorry for not validating the HTML file before creating the PR.
Update the genToc funtion to make the name required in the Code node,
and add an additional optional field for the expected error, to use with
test_err, test_safety and obj_err.
Update langref.html.in to ensure all code blocks have a name that
- is unique, so that a doctest can be identified by it
- is descriptive
For test, test_err and test_safefy, ensure that the doctest name starts
with "test_", excluding doctests in the "Zig Test" section and doctests
that are imported by other doctests.
Ensure that the indentation of code_begin and code_end blocks are
consistent.
Fix a typo in pointer_arthemtic.
In a syntax_block the code always start on a separate code, expect for
C, JavaScript, Peg and with Zig inline assembly.
Ensure that the code starts on a separate line, even in cases where
there is only one line.
Ensure that the end_syntax_block is always on a separate line and that
the indentation is consistent.
The current compiler ignores the UTF-8 BOM if it is at the start of the
file, and disallows it anywhere else. Document it in the Source Encoding
section.
Add the new addrspace keyword in the Keyword Reference section, without
documentation.
Move the linksection keyword in order to keep the keywords list sorted.
The deallocations of the process arguments are unnecessary, since the
memory will be deallocated by arena.deinit().
The deallocations are incorrect, since ArgIterator.next() returns a
slice pointing to the iterator's internal buffer, that should be
deallocated with args_it.deinit().
