Re: Fwd: [patch libffi]: Add support for fastcall/thiscall to x86 variant of libffi for PR 51500

[Kai Tietz <ktietz70 at googlemail dot com>]

Hi,

I added some testcases and reworked patch about thiscall/fastcall.
Initial patched worked fine for thiscall-convention, but had
wrong-behavior in some cases for fastcall-convention.

ChangeLog

	argument to prototype for specify calling-convention.
