https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234291 Bug ID: 234291 Summary: LLVM does not support CPU feature detection on non-x86 platforms Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: greg@unrelenting.technology llvm::sys::getHostCPUFeatures (lib/Support/Host.cpp): https://llvm.org/doxygen/Host_8cpp_source.html#l01427 only supports Linux's /proc/cpuinfo on non-x86 architectures. One known user of that API is lang/ponyc, where I contributed a workaround: https://github.com/ponylang/ponyc/commit/81ba52c90cb87a049be8052754a8b031de= 59593d There should be versions of this function for FreeBSD/aarch64 (by reading ID_AA64ISAR0_EL1/ID_AA64PFR0_EL1/ID_AA64ISAR1_EL1 in userspace) and armv\d|powerpc(64)? (via elf_aux_info). --=20 You are receiving this mail because: You are the assignee for the bug.=
