This looks ok. However - we have RtlIsEcCode available unconditionally for
all architectures in mingw-w64-crt/lib-common/kernel32.def.in (since
d367cc9d75f3669961463c631d1ab65434e27517).
Since arm64ec operates in the x86_64 "namespace" when it comes to DLLs, I
presume this means that the function, technically, also is available on plain
regular x86_64. Does it exist in pure aarch64 kernel32.dll as well? (From
looking at the hybrid arm64x kernel32.dll on win11, the function does seem to
be listed in the default printout from "llvm-readobj --coff-exports", I guess
that's the native aarch64 version of things?)
It does seem to be missing from the arm32 version of kernel32.dll though.
Not sure if we strictly need to add ifdefs to the .def.in to make sure it's
not included in the import library there - but I think the header ifdef here
could be wider, to allow it to be called elsewhere too? Although as WinSDK
only exposes the function in arm64ec mode, perhaps it's best to just match
that.
Another aspect I noted here; this function is also listed in
api-ms-win-core-rtlsupport-l1-2-2.dll according to the MS docs, but we
don't have an apiset import library for that one. (I guess that we should
do a bigger update of the apisets in order to pick it up there.)
