Calvin Rose a5def77bfe Add support for struct return values. 2022-06-10 12:25:08 -05:00
Calvin Rose 9ecb5b4791 Add native-read function as inverse to native-write. 2022-06-10 09:38:52 -05:00
Calvin Rose 1cc48a370a Add native-write, which will write structs to buffers.
Useful for testing as well as useful in its own right. Begs
for an inverse, native-read which would convert byte data
to native structs.

Calvin Rose f1ec8d1e11 Beginning of struct support.
TODO:
- struct return values
- support for unions in signatures
- more testing
- complex types
- packed structs
- writing structs to buffers (useful and we have most of the machinery).

Calvin Rose 9d9cb378ff Don't include alloca.h, not in MSVC. 2022-06-08 09:59:13 -05:00
Calvin Rose f92aac14aa Only enable FFI on x86-64, non-windows OSes. 2022-06-08 09:50:31 -05:00
Calvin Rose 3f27d78ab5 Add some FFI testing and more improvements to sysv abi.
Add support for integer return and floating point return variants, as
well as arguments on the stack. Start flushing out struct arguments.

Still needed:
- structs (packed and unpacked)
- complex numbers
- long doubles
- MASM alternative for windows (you can technically use sysv abi on
  windows)
- more calling conventions.
