* PR #1644: unscaledcycleclock: remove RISC-V supportaurel322024-03-222-16/+4
| | | | | | | | | | | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1644 Starting with Linux 6.6 [1], RDCYCLE is a privileged instruction on RISC-V and can't be used directly from userland. There is a sysctl option to change that as a transition period, but it will eventually disappear. The RDTIME instruction is another less accurate alternative, however its frequency varies from board to board, and there is currently now way to get its frequency from userland [2]. Therefore this patch just removes the code for unscaledcycleclock on RISC-V. Without processor specific implementation, abseil relies on std::chrono::steady_clock::now().time_since_epoch() which is basically a wrapper around clock_gettime (CLOCK_MONOTONIC), which in turns use __vdso_clock_gettime(). On RISC-V this VDSO is just a wrapper around RDTIME correctly scaled to use nanoseconds units. This fixes the testsuite on riscv64, tested on a VisionFive 2 board.

* PR #1553: Adapt to syscall(2) removal in OpenBSDTheo Buehler2023-10-251-9/+6
| | | | | | | | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1553 OpenBSD will remove its generic syscall(2) interface, so setting the ABSL_HAVE_SYSCALL_WRITE define will result in a linking failure soon. Make direct use of the write(2) syscall instead. OpenBSD's libc does not do any buffering for write, so there is no change of behavior. A [variant of this patch][1] has been in use since early this year in OpenBSD's ports. There's no need to set ABSL_LOW_LEVEL_WRITE_SUPPORTED since that's already done a few lines up.

* Remove the legacy thread annotation spellingsDerek Mauro2023-08-281-280/+0
| | | | | | | | | | | | | | | | The legacy thread annotations were spellings that were not prefixed with ABSL_ and caused conflicts with other libraries. These spellings have been removed by default for a while, but could have been added back with the temporary compile flag -DABSL_LEGACY_THREAD_ANNOTATIONS. This change completely removes the legacy spellings. If you were relying on the legacy spellings, the fix is straightforward. Simply add the ABSL_ prefix. For example, GUARDED_BY() becomes ABSL_GUARDED_BY(). PiperOrigin-RevId: 560874026 Change-Id: Id072e67435472220ea4f43ccbf267028c13feba7
* PR #1509: Allow building when targeting WASIAnuraag Agrawal2023-08-151-4/+10
| | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1509 WASI is similar to emscripten, providing a syscall layer to WebAssembly focused on server side applications. There are some config knobs that are in place to allow building the repo for emscripten which also need to support wasi (as built with LLVM). Aside from that, there are still some features it supports less than escripten, for example related to signals, causing the build to be even more limited for it.

* Name anonymous memory allocations on Linux.Abseil Team2023-04-121-0/+16
| | | | | | | | | | | | | | | | | | | Use Linux's prctl(PR_SET_VMA) system call to name memory arenas being allocated using mmap(MAP_ANONYMOUS). This change allows Abseil's memory arena(s) to be distinguished from other uses of anonymous memory within a process, which in turn helps investigations into the memory usage of applications. The change adds a new prctl() system call to the code paths that call mmap(). This is not expected to add significant overhead to applications. The call to prctl(PR_SET_VMA, ...) can fail if the Linux kernel in use was not configured with the CONFIG_ANON_VMA_NAME kernel option. This should be OK since the naming memory regions is primarily a debugging aid. PiperOrigin-RevId: 523687348 Change-Id: Ie404e5eeef0a6da53330b3a56149c4f3bc6bf5c7
