docgen HTML escapes characters inside of `syntax_block`s. This commit replaces the escaped
greater than with the `>` character. No other occurrences were found.
Fixes #9840

There were two things to resolve here:
* Snektron's branch edited Zir printing, but in master branch
I moved the printing code from Zir.zig to print_zir.zig. So that
just had to be moved over.
* In master branch I fleshed out coerceInMemory a bit more, which
caused one of Snektron's test cases to fail, so I had to add
addrspace awareness to that. Once I did that the tests passed again.

In a previous commit (f4d3d29), syntax checking for code blocks with the
`syntax` type was disabled due to a change in astgen now checking the existence of
identifiers. The change in astgen caused some code samples in the language
reference to cause compilation errors.
This commit updates the code samples in the language reference and
re-enables syntax checking. Some code samples have been changed to unchecked
syntax blocks using `{#syntax_block#}` when suitable.
|
|
This edit allows the reader to understand the syntax this section is talking about more quickly – they don’t have to read the whole code block and understand which part of it demonstrates the feature being described.

* langref: add some more "see also" links for atomics
* Add the following AIR instructions
- atomic_load
- atomic_store_unordered
- atomic_store_monotonic
- atomic_store_release
- atomic_store_seq_cst
- atomic_rmw
* Implement those AIR instructions in LLVM and C backends.
* AstGen: make the `ty` result locations for `@atomicRmw`, `@atomicLoad`,
and `@atomicStore` be `coerced_ty` to avoid unnecessary ZIR
instructions when Sema will be doing the coercions redundantly.
* Sema for `@atomicLoad` and `@atomicRmw` is done, however Sema for
`@atomicStore` is not yet implemented.
- comptime eval for `@atomicRmw` is not yet implemented.
* Sema: flesh out `coerceInMemoryAllowed` a little bit more. It can now
handle pointers.

The language reference's HTML has been updated to be more semantically correct.
This also helps to improve the document's accessibility concerns.
* Document structure has single h1, other header sections start at h2, nav sections w/ aria labels, main section
* Zig's homepage is linked, Zig Standard Library section link to it
* Tables have caption and scoping rows and columns
* Code blocks are figures with figure captions citing source files
* Change line height 1.5 to include table of contents as well
* Luminosity contrast ratios have been adjusted to 7:1
* Dark mode colors adjusted to reduce eye strain
* Links have default browser underline with hover and focus effects
* Asides, definition lists, keyboard inputs, program outputs are represented semantically

- adds 1 simple behavior tests for each
which does integer and vector ops at
runtime and comptime
- adds bigint_*_sat() methods for each
- use CreateIntrinsic() which accepts a
variable number of arguments to pass
the scale parameter
* update langref
- added case to test/compile_errors.zig given floats
- explain upstream bug in llvm.smul.fix.sat and link to #9643 in langref and commented out test cases
* sat-arithmetic: skip mul tests if arch == .wasm32 because ci is erroring with 'LLVM ERROR: Unable to expand fixed point multiplication' when compiling for wasm32

The grammar does not need these as keywords; they are merely primitives
provided by the language the same as `void`, `u32`, etc.

|
This is a backwards-compatible language change.
Previously, `@intToEnum` coerced its integer operand to the integer tag
type of the destination enum type, often requiring the callsite to
additionally wrap the operand in an `@intCast`. Now, the `@intCast` is
implicit, and any integer operand can be passed to `@intToEnum`.
The same as before, it is illegal behavior to pass any integer which does
not have a corresponding enum tag.

The async/await documentation was somewhat hard for me to follow when first learning. Two particular sticking points were
1. The alphabet example constructing the string "abcdefghi" breaks the stated rule that every async has a matching await.
2. It was somewhat unclear to me what the rules for control flow were around async/await constructs.
I've tried to improve this documentation with some minimal explanatory edits, which are correct to the best of my beginner's understanding & experimentation.

* Make clearer inline code blocks in language reference paragraphs
This commit makes the inline code blocks within paragraphs standout against the
descriptive text. The code blocks within tables are left un-styled.
The line-height of the paragraphs has been set to 1.7 based on recommendations
from MDN Web Docs and W3C. The value is unitless based on the recommendation.
Closes #9316, #6313
* Make clearer inline code blocks in language reference paragraphs
Goal: To improve legibility of inline code blocks in the language reference.
This commit alters the styles of code HTML elements in paragraphs, unordered
lists, ordered lists, tables, and preformatted text elements.
Most of the changes here are taken from suggestions from @dbandstra on GitHub
in response to a code review.
* p, ul, ol, but not #toc are set to the same line-height
* p, ul, ol, and table have the same inline code styles
* The inline code background color set to match the preformatted code blocks in
the light theme and dark theme. The border colors are adjusted as well.
* The preformatted code block font size is set to default. The 12pt setting was removed.
The line-height of paragraphs is set to 1.5. This value is chosen based on
recommendations from W3C [1] via MDN Web Docs [2] and the contents of the
language reference.
The MDN Web Docs offers two recommendations:
1. Use a unitless number for line-height.
2. Use a minimum value of 1.5 for main paragraph content.

Closes #6313, #9316
* Set language reference line-height and pre code border color
This commit is an update to a group of commits with the goal of improving the
legibility of the language reference. In this commit, the line-height is now set
in the `#contents` ID and reset to normal for preformatted code blocks. This
change better separates lines of all main content text for legibility.
Closes: #9316, #6313
* Style the language reference code elements
This commit sets the style of the HTML code element. Since preformatted code
blocks have an overriding style, this is safe to set for all inline code elements.

This is the first commit in which some behavior tests are passing for
both stage1 and stage2.
|

@select(
comptime T: type,
pred: std.meta.Vector(len, bool),
a: std.meta.Vector(len, T),
b: std.meta.Vector(len, T)
) std.meta.Vector(len, T)
Constructs a vector from a & b, based on the values in the predicate vector. For indices where the predicate value is true, the corresponding
element from the a vector is selected, and otherwise from b.

* removed deprecated coercion: [X]T => [] const T
* Fixed tests and added desc for first test
* Improved heading
|
|
* Added doc comments for `std.Target.ObjectFormat` enum
* `std.Target.oFileExt` is removed because it is incorrect for Plan-9
targets. Instead, use `std.Target.ObjectFormat.fileExt` and pass a
CPU architecture.
* Added `Compilation.Directory.joinZ` for when a null byte is desired.
* Improvements to `Compilation.create` logic for computing `use_llvm`
and reporting errors in contradictory flags. `-femit-llvm-ir` and
`-femit-llvm-bc` will now imply `-fLLVM`.
* Fix compilation when passing `.bc` files on the command line.
* Improvements to the stage2 LLVM backend:
- cleaned up error messages and error reporting. Properly bubble up
some errors rather than dumping to stderr; others turn into panics.
- properly call ZigLLVMCreateTargetMachine and
ZigLLVMTargetMachineEmitToFile and implement calculation of the
respective parameters (cpu features, code model, abi name, lto,
tsan, etc).
- LLVM module verification only runs in debug builds of the compiler
- use LLVMDumpModule rather than printToString because in the case
that we incorrectly pass a null pointer to LLVM it may crash during
dumping the module and having it partially printed is helpful in
this case.
- support -femit-asm, -fno-emit-bin, -femit-llvm-ir, -femit-llvm-bc
- Support LLVM backend when used with Mach-O and WASM linkers.

c_void is *not* simply `const c_void = opaque{};`. It has unique
semantics as any pointer type may coerce to `*c_void` which is not true
for an arbitrary `*opaque{}`.

The "Zig Test" section of the language reference has been moved between the
current "Hello World" section and the "Comments" section. This was done to
introduce the Zig test syntax before it is used in later sections.
The description of the Zig test feature has NOT been updated in this commit.
Closes #5837

This modifies the lock semantics from using AccessMode to using
NtLockFile/NtUnlockFile.
This is a breaking change.

* Remove parser error on double ampersand
* Add failing test for double ampersand case
* Add error when encountering double ampersand in AstGen
"Bit and" operator should not make sense when one of its operands
is an address.
* Check that 2 ampersands are adjacent to each other in source string
* Remove cases of unused variables in tests

This is for consistency with the documentation on sentinel-terminated
{arrays,slices,pointers} which already use `N` for a comptime-inferred
size rather than `X`.
Also adds a behavioral test to assert that a string literal is returned.
|
|
This was already the case, but the documentation failed to point out
that the returned value is of type `*const [N:0]u8`, i.e. that of a
string literal.
Also adds a behavioral test to assert that this is the case.
