Specifying this argument causes steps that specify a max_rss that exceeds the
total max_rss value of the runner to be skipped, instead of failing.

Add a `.rc` -> `.res` compiler to the Zig compiler
|
|
There seems to be an LLVM bug with this feature. Since it's new, let's
collect more information before adding it.

* some manual fixes to generated CPU features code. in the future it
would be nice to make the script do those automatically. I suspect
the sm_90a thing is a bug in LLVM.
* add liteos to various target OS switches. I know nothing about this
OS; someone will need to work specifically on support for this OS
when the time comes to support it properly in zig.
* while waiting for the compiler, I went ahead and made more
conservative choices about when to use `inline` in std/Target.zig

New OSs:
* UEFI
* LiteOS
New ABI:
* OpenHOS
Also update the LLD driver API wrappers.

Currently, the compiler (like @typeName) writes it `fn(...) Type` but
zig fmt writes it `fn (...) Type` (notice the space after `fn`).
This inconsistency is now resolved and function types are consistently
written the zig fmt way. Before this there were more `fn (...) Type`
occurrences than `fn(...) Type` already.

The _environ variable that is populated when linking libc on Windows does not support Unicode keys/values (or, at least, the encoding is not necessarily UTF-8). So, for Unicode support, _wenviron would need to be used instead. However, this means that the keys/values would be encoded as UTF-16, so they would need to be converted to UTF-8 before being returned by `os.getenv`. This would require allocation which is not part of the `os.getenv` API, so `os.getenv` is not implementable on Windows even when linking libc.
Closes https://github.com/ziglang/zig/issues/8456

The include directories used when preprocessing .rc files are now separate from the target, and by default will use the system MSVC include paths if the MSVC + Windows SDK are present, otherwise it will fall back to the MinGW includes distributed with Zig. This default behavior can be overridden by the `-rcincludes` option (possible values: any (the default), msvc, gnu, or none).
This behavior is useful because Windows resource files may `#include` files that only exist with in the MSVC include dirs (e.g. in `<MSVC install directory>/atlmfc/include` which can contain other .rc files, images, icons, cursors, etc). So, by defaulting to the `any` behavior (MSVC if present, MinGW fallback), users will by default get behavior that is most-likely-to-work.
It also should be okay that the include directories used when compiling .rc files differ from the include directories used when compiling the main binary, since the .res format is not dependent on anything ABI-related. The only relevant differences would be things like `#define` constants being different values in the MinGW headers vs the MSVC headers, but any such differences would likely be a MinGW bug.

std.http: handle Expect: 100-continue, improve redirect logic, add Client.fetch for simple requests

I have updated Felix's ZigAndroidTemplate to work with the latest
version of Zig and we are exploring adding Android support to Mach engine.
`std.c.getcontext` is _referenced_ but not _used_, and Android's bionic libc
does not implement `getcontext`. `std.os.linux.getcontext` also cannot be
used with bionic libc, so it seems prudent to just disable this extern for now.
This may not be the perfect long-term fix, but I have a golden rebuttal to that:
before I was unable to compile Zig applications for Android, and now I can.

when source_line is 0
The zero value needs special handling since it means 'no source line' and should be preserved through the copy.

compiler: implement destructuring syntax
|
|
The new `@depedencies` module contains generated code like the
following (where strings like "abc123" represent hashes):
```zig
pub const root_deps = [_]struct { []const u8, []const u8 }{
.{ "foo", "abc123" },
};
pub const packages = struct {
pub const abc123 = struct {
pub const build_root = "/home/mlugg/.cache/zig/blah/abc123";
pub const build_zig = @import("abc123");
pub const deps = [_]struct { []const u8, []const u8 }{
.{ "bar", "abc123" },
.{ "name", "ghi789" },
};
};
};
```
Each package contains a build root string, the build.zig import, and a
mapping from dependency names to package hashes. There is also such a
mapping for the root package dependencies.
In theory, we could now remove the `dep_prefix` field from `std.Build`,
since its main purpose is now handled differently. I believe this is a
desirable goal, as it doesn't really make sense to assign a single FQN
to any package (because it may appear in many different places in the
package hierarchy). This commit does not remove that field, as it's used
non-trivially in a few places in the build runner and compiler tests:
this will be a future enhancement.

This change implements the following syntax into the compiler:
```zig
const x: u32, var y, foo.bar = .{ 1, 2, 3 };
```
A destructure expression may only appear within a block (i.e. not at
comtainer scope). The LHS consists of a sequence of comma-separated var
decls and/or lvalue expressions. The RHS is a normal expression.
A new result location type, `destructure`, is used, which contains
result pointers for each component of the destructure. This means that
when the RHS is a more complicated expression, peer type resolution is
not used: each result value is individually destructured and written to
the result pointers. RLS is always used for destructure expressions,
meaning every `const` on the LHS of such an expression creates a true
stack allocation.
Aside from anonymous array literals, Sema is capable of destructuring
the following types:
* Tuples
* Arrays
* Vectors
A destructure may be prefixed with the `comptime` keyword, in which case
the entire destructure is evaluated at comptime: this means all `var`s
in the LHS are `comptime var`s, every lvalue expression is evaluated at
comptime, and the RHS is evaluated at comptime. If every LHS is a
`const`, this is not allowed: as with single declarations, the user
should instead mark the RHS as `comptime`.
There are a few subtleties in the grammar changes here. For one thing,
if every LHS is an lvalue expression (rather than a var decl), a
destructure is considered an expression. This makes, for instance,
`if (cond) x, y = .{ 1, 2 };` valid Zig code. A destructure is allowed
in almost every context where a standard assignment expression is
permitted. The exception is `switch` prongs, which cannot be
destructures as the comma is ambiguous with the end of the prong.
A follow-up commit will begin utilizing this syntax in the Zig compiler.

Insn.st() can be used with dynamic size just like Insn.stx(), which is
relevant in a code generation context.
using ImmOrReg caused an error as its fields were ordered differently than
Source.

This will allow users to construct e.g. a ComptimeStringMap that uses case-insensitive ASCII comparison.
Note: the previous ComptimeStringMap API is unchanged (i.e. this does not break any existing code).
|
|
`std.process.getEnvMap` or `std.process.getEnvVarOwned` should be used
instead, requiring allocation.

Follow up to https://github.com/ziglang/zig/pull/17136. The `Dir.rename files` test has now also been seen to fail in CI, so now all rename tests are skipped for the UNC path type. This is a heavy handed approach to hopefully get rid of any flakiness related to rename & UNC paths. See https://github.com/ziglang/zig/issues/17134

Now that allocator.resize() is allowed to fail, programs may wish to
test code paths that handle resize() failure. The simplest way to do
this now is to replace the vtable of the testing allocator with one
that uses Allocator.noResize for the 'resize' function pointer.
An alternative way to support this testing capability is to augment the
FailingAllocator (which is already useful for testing allocation failure
scenarios) to intentionally fail on calls to resize(). To do this, add a
'resize_fail_index' parameter to the FailingAllocator that causes
resize() to fail after the given number of calls.

This fixes the case where IPv6 address parsing incorrectly succeeded on
