commit 7b86b92ec1bdfad552ece3eaa28bd8d28dff9a82 Author: Dimitry Andric <[email protected]> AuthorDate: 2024-04-07 00:07:38 +0000 Commit: Dimitry Andric <[email protected]> CommitDate: 2024-04-20 10:29:09 +0000 Fix arm64 build after llvm 18.1.3 upgrade Apparently clang 18 has become more strict about using floating point registers in inline assembly when -mgeneral-regs-only is used. This causes sys/arm64/arm64/vfp.c to fail to compile, with "error: instruction requires: fp-armv8", and "error: expected readable system register". To fix it, similar to other files compiled for arm64, disable -mgeneral-regs-only for this particular file.
