[PATCH 0/1] MR1772: ntdll: Make sure xmm6-xmm15 are always restored in unix call dispatcher
by Torge Matthies (＠tmatthies) Dec. 11, 2022

Dec. 11, 2022

If after a unix call `frame->restore_flags` was not 0 but did not include either `CONTEXT_FLOATING_POINT` or `CONTEXT_XSTATE`, xmm6-xmm15 were not restored to their previous values. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1772

[PATCH v2 0/7] MR1752: Draft: RFC: Make syscall functions sysv_abi on x64
by Torge Matthies (＠tmatthies) Dec. 11, 2022

Dec. 11, 2022

This removes 20 `movaps` instructions from every syscall that calls a sysv_abi function, plus an `and` for stack alignment and some other instructions depending on the function. In `NtAllocateLocallyUniqueId` for example this reduces the number of instructions from 63 to 36. I don't entirely understand the llvm-mca output but here are the before and after stats that it outputs for that function: Before Iterations: 100 Instructions: 6300 Total Cycles: 3335 Total uOps: 6300 Dispatch Width: 6 uOps Per Cycle: 1.89 IPC: 1.89 Block RThroughput: 15.0 After Iterations: 100 Instructions: 3600 Total Cycles: 1514 Total uOps: 3600 Dispatch Width: 6 uOps Per Cycle: 2.38 IPC: 2.38 Block RThroughput: 6.0 This currently depends on the stack being aligned by the syscall dispatcher, which afaict is the case if `sizeof(struct syscall_frame) % 16 == 0`. If that is not good enough I can add an `andq $~15,%rsp` somewhere. One question I have is whether we want to continue supporting CDECL syscalls (only `wine_server_call`, `wine_server_fd_to_handle` and `wine_server_handle_to_fd`)? If we do, this adds a bit of complexity to the syscall dispatcher, see the commit "FIXUP ntdll: Support CDECL syscalls." If we don't, and make those syscalls WINAPI instead, then for every call to those functions on x86 it seems to either change nothing or add one `add` instruction. However we of course lose the ability to make CDECL syscalls. -- v2: Revert "ntdll: Make CDECL syscalls WINAPI instead."
