The initial purpose is to workaround the LLVM bug
https://llvm.org/bugs/show_bug.cgi?id=26554 for OpenBSD.
By default, the `cpu` is defined to `generic`. But with a 64bit
processor, the optimization for `generic` will use invalid asm code as
NOP (the generated code for NOP isn't a NOP).
According to #20777, "x86-64" is the right thing to do for x86_64
builds.
Closes: #31363

Previously the docs suggested that '❤️' doesn't fit in a char because
it's 6 bytes. But that's misleading. 'a̚' also doesn't fit in a char,
even though it's only 3 bytes. The important thing is the number of code
points, not the number of bytes. Clarify the primitive char docs around
this.
The first time I read the docs for `insert()`, I thought it was saying it didn't update existing *values*, and I was confused. Reword the docs to make it clear that `insert()` does update values.

This commit rebases our LLVM submodule on the most recent tip of the
`release_38` branch of LLVM. There's been a few fixes and this notably fixes the
assertion error in #31702.
Closes#31702
This commit rebases our LLVM submodule on the most recent tip of the
`release_38` branch of LLVM. There's been a few fixes and this notably fixes the
assertion error in #31702.
this improves typeck performance by 5% (LLVM times are still huge).
Basically fixes#25916 (still O(n^2), but the example takes <1s to
compile).

This PR disallows non-inline modules without path annotations that are either in a block or in an inline module whose containing file is not a directory owner (fixes#29765).
This is a [breaking-change].

The issue was that the const evaluator was returning an error because
the feature flag const_indexing wasn't turned on. The error was then
reported as a bug.
Fixes#29914
Thanks for catching this @tamird. Here's a quick fix. I didn't pick "let the linker link dead code" or "link dead code" because it would add no extra information to the flag name. Here's a another proposal.

Because we no longer use `GetFileAttributesExW` FileAttr is never created directly from `WIN32_FILE_ATTRIBUTE_DATA` anymore. So we should no longer store FileAttr's attributes in that c struct.

Is this what you had in mind?
use CXX value found at configure time inside run-make tests.
it permits OpenBSD to pass llvm-module-pass test (which use CXX
variable).

This follows the pattern already used for stat functions from #31551. Now
`ftruncate`, `lseek`, and `readdir_r` use their explicit 64-bit variants for
LFS support, using wider `off_t` and `dirent` types. This also updates to
`open64`, which uses no different types but implies the `O_LARGEFILE` flag.
Non-Linux platforms just map their normal functions to the 64-bit names.

This enables `*` in all type positions in doc searches, which I often
want in order to find functions that create or convert specific
types (e.g. `* -> vec`) but I don't actually know what kinds of input
they expect.
I actually started working on this because of #31598, but I've wanted it
several times when exploring new crates.
