I am not a proponent of third-party dependencies.
I am not a proponent of reimplementing everything but the kitchen sink
because of other people's adversity to reusing existing solutions.
I don't mind reusing existing solutions, I often do so.
But keeping dependencies on external libs to a minimum is also a concern.
Then, there is a practical issue:
I doubt libffi knows the Delphi calling conventions and the pascal
calling convention where the callee clears the stack (or was it vice
versa)? Since that is our main target group, I consider this a serious
problem.
It does support those calling conventions.
Well.
Prior to posting my statement, I checked, and it is not in the list of
supported architectures.
"Delphi" is not an architecture. The "register" calling convention is
part of the x86 support. If you look at $ffisrc/src/x86/ffitarget.h
you'll notice a FFI_REGISTER variable which is the default Delphi
calling convention.
