After changing mbstate_t to mbstate we forgot to change the
character_converter files to reflect it.

* Get rid of libc_errno assignments in str_to_* __support tests, since
those API have been migrated to return error in a struct instead.
* Migrate tests for atof and to strto* functions from <stdlib.h> and for
strdup from <string.h> to use ErrnoCheckingTest harness.
I'm setting up a buildbot for arm32 using qemu and qemu doesn't support
PR_GET_THP_DISABLE.
Disable the test for now while we figure out what to do about that.
Also disable for riscv because we may do the same for riscv buildbots.
Add `CLOCKS_PER_SEC` and the older `CLK_TCK`. Allows the user to define
a `__CLK_TCK` to override if necessary.
Also add an extra column for embedded AArch64 in `time.rst`
The string_utils.h file previously included both memcpy and bzero. There
were no uses of bzero, and only one use of memcpy which was replaced
with __builtin_memcpy.
Also fix strsep which was broken by this change, fix a useless assert of
"sizeof(char) == sizeof(cpp::byte)", and update the bazel.
Summary:
This improves performance by reducing the amount of RMW operations we
need to do to a single slot. This improves repeated allocations without
much contention about ten percent.
Fixes [#141505](https://github.com/llvm/llvm-project/issues/141505)
The main intention behind this PR is to update the
LibCTargetArchitecture for arm64 to use the implementation of aarch64
architecture and not arm32.
This is a historical issue , and is a blocker to issue #138407.
The intended fix is to set the `LibCTargetArchitecture` to aarch64 when
it matches arm64 , this in turn would help us run darwin/aarch64
specific code on our MacOs pipeline in the git actions.
Methods used to search and find "darwin/arm" directories was
1. "find . -type d -path "*/libc/*/darwin/arm" in a linux terminal to
check for arm specifically
2. "find . -type d -path "*/libc/*/darwin/*" to ensure there are no
directories that are named "*arm*" where star is a wildcard for any
character.
See PR #132823 for a previous change to sys/epoll tests, and prior
changes before that.
ErrnoCheckingTest ensures that errno is properly reset at the beginning
of the test case, and is validated at the end of it. This change removes
many instances of manual errno manipulation.
Summary:
This is the big patch that implements an efficient device-side `malloc`
on the GPU. This is the first pass and many improvements will be made
later.
The scheme revolves around using a global reference counted pointer to
hand out access to a dynamically created and destroyed slab interface.
The slab is simply a large bitfield with one bit for each slab. All
allocations are the same size in a slab, so different sized allocations
are done through different slabs.
Allocation is thus searching for or creating a slab for the desired
slab, reserving space, and then searching for a free bit. Freeing is
clearing the bit and then releasing the space.
This interface allows memory to dynamically grow and shrink. Future
patches will have different modes to allow fast first-time-use as well
as a non-RPC version.
These functions don't have a _time64 variant, so we can't use time_t
directly (since our time_t is a uint64_t). The workaround is to use
longs when doing the syscall and write back when necessary.
