https://sourceware.org/cgit/valgrind/commit/?id=7f71b26b924df4e81aa2f39cd5075338fb25bb8b commit 7f71b26b924df4e81aa2f39cd5075338fb25bb8b Author: Paul Floyd <pj...@wa...> Date: Sun Nov 9 19:28:13 2025 +0100 Darwin: rework syscall arg handling There were numerous issues, particularly with syscall SYS_syscall and the scalar tests. Only tested on amd64, I don't have access to an OSX 10.12 or earlier machine to do any testing. The key elements in VG_(client_syscall) are, when the PRE wrapper does not handle the syscall 1. getSyscallArgsFromGuestState 2. getSyscallArgLayout 3. call PRE wrapper either blocking 4. putSyscallArgsIntoGuestState 5. do_syscall_for_client or non-blocking 6. VG_(do_syscall) What has changed ---------------- struct SyscallArgs now like FreeBSD, stores both the canonical_sysno (which is the final syscall number, never SYS_syscall) and the original_sysno (which can be SYS_syscall). These get set in getSyscallArgsFromGuestState which has changed accordingly. getSyscallArgsFromGuestState has changed to always get the layout coresponding to the canonical layout. This was the cause of the problems with the scalar tests - the arguments were effectively out by one. Many subsequent changes to the scalar test, filter and expected. The scalar test still isn't quite right. __NR_kevent_qos is missing a scalar error from argument 6. That's the one with special case handling because it is a register argument for a normal syscall but a stack argument for syscall SYS_syscall.
