Re: Please help prep for a new libffi release

[Anthony Green <green@moxielogic.com>]

I spent some time trying to fix the 32-bit x86 results.  As it
happens, libffi is doing things mostly right.  It's GCC that can't
return small structs (<= 16 byte) properly for any of the MS ABIs.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105932
I'm just going to ignore this for now and force the CI tests to pass
with new rlgl policy.

I'll probably spin out the new release in the next day or two.  As far
as I can tell there are no regressions.

These are the highlights:

        All struct args are passed by value, regardless of size, as per ABIs.
        Enable static trampolines for Cygwin.
        Add support for Loongson's LoonArch64 architecture.
        Fix x32 static trampolines.
        Fix 32-bit x86 stdcall stack corruption.
        Fix ILP32 aarch64 support.
