--- Comment #29 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
CCing some folks familiar with Windows, while Martin has committed a mmap b=
ased
solution, I think it will not work on Windows, but
CreateFileMapping/MapViewOfFile/UnmapViewOfFile/CloseHandle could be a Wind=
ows
replacement for that:
https://gcc.gnu.org/pipermail/gcc-patches/2021-February/565575.html
Can anyone of you please have a look into that?
I don't have access to Windows (and my experience with it is 25+ years old
anyway), and Martin doesn't have either.=
