  "message": "PR #2147: Fix FreeBSD/PowerPC* issues\n\nImported from GitHub PR https://github.com/abseil/abseil-cpp/pull/2147\n\nFixes two issues on FreeBSD PowerPC architectures:\n\n1. UnscaledCycleClock::Frequency():\n   The `kern.timecounter.tc.timebase.frequency` sysctl is registered in the\n   FreeBSD kernel as CTLTYPE_U64 (uint64_t). Previously, sysctlbyname() read\n   directly into a `double` variable without type conversion, causing the raw\n   integer bits to be reinterpreted as a double.\n\n2. StacktracePowerPCGetLRPtr():\n   When compiler ABI macros are absent, the unwinder falls back to OS checks.\n   Previously, __FreeBSD__ was grouped with __APPLE__ to read the saved Link\n   Register at sp[2]. While sp[2] (offset 16) is correct for 64-bit ELF / AIX /\n   Darwin, the 32-bit PowerPC SysV ELF ABI saves the LR at sp[1] (offset 4).\n   Fix by keying the fallback on __PPC64__ for 64-bit (sp[2]) versus __linux__\n   and __FreeBSD__ for 32-bit (sp[1]).\n\nMerge 8f4431186a50594b7dced86835d4b0a5be708dd6 into 2adadbc666a2da417194f73694346f41969e0777\n\nMerging this change closes #2147\n\nPiperOrigin-RevId: 976301714\nChange-Id: I584c7231e5071cde514a02c082a49f829a414963\n",
