This was implemented in vkd3d 1.10. Another known feature that has to be enabled with compatibility flag is d3d9 style sampling functions. We currently don't do that, making them supported unconditionally.

v2: d3dcompiler: Enable semantic names mapping in compatibility mode.

> I'd rather accumulate flags while compiling the shader rather than doing another pass at the end. Not a terribly strong opinion, though.
In principle I'd be inclined to agree, but this approach seems appropriate this close to the release. Ultimately the tpf writer should get this from the vsir_program, of course.

For all mach vm operations this removes the task suspend and resume, which are not needed.
This uses `mach_vm_read_overwrite` to read into a caller-specified buffer, saving the `mach_vm_deallocate` call (bringing all read operations down to 1 syscall from 4).
The only alignment restriction on `mach_vm_write` according to the original CMU documentation is that data is
> [pointer to page aligned in array of bytes] An array of data to be written.
(In practice it also works with arbitrary addresses on macOS, but it probably doesn't hurt to follow the original specifications here).
The only other reference that these read/writes should be page-aligned is from the GNU Hurd documentation
> The current implementation requires that address, data and data_count all be page-aligned. Otherwise, KERN_INVALID_ARGUMENT is returned.
which I assume was the reason why this was originally done (plus it sounds to me like they will fix that in the future and 4fe19777 already broke GNU Hurd support anyways, if that was supposed to be working).
Also this includes the missing mach part of 5b1f3b14, which was only applied to the ptrace backend, and together with the `write_process_memory` rework, this gets rid of all fixmes in mach.c
--
v3: server: Simplify mach write_process_memory.
server: Use mach_vm_read_overwrite in get_selector_entry.
server: Use mach_vm_read_overwrite in read_process_memory.
