Notably, the glue layer side of the changed multiple interface
inheritance layout (DMD a54e89d) has not been implemented yet.
This corresponds to DMD commit 3f6a763c0589dd03c1c206eafd434b593702564e.
- Remove byval attribute
- Do not reverse parameter list
The latter point is required by the spec at http://dlang.org/spec/abi.html:
"The extern (C) and extern (D) calling convention matches the C calling
convention used by the supported C compiler on the host system."
This is required to resolve the type for AAPCS/AAPCS64.
Up to now it was not necessary because only char* was used.
AAPCS/AAPCS64 use a special extern(C++) struct __va_list.
Also adds the CMake infrastructure to compile and link the D source files.
The build is partially broken:
- A few files in Phobos and druntime do not build
- MSVC build is broken because of unresolved symbols involving reals
* x86: Return most POD aggregates <= 8 bytes in registers
* For extern(D), as in official Win32 D ABI specs [previously: sret]
* For all other calling conventions too, except for Linux and NetBSD
[previously: OSX and MSVC only]
* MSVC++ and extern(C++): treat structs with constructors as non-POD,
for both x86 and Win64 ABIs
* Win64: Pass and return magic C++ structs directly as LL aggregates,
rendering MSVCLongDoubleRewrite obsolete
* x86: Fix regression introduced by previous commits wrt. passing the
last struct argument in EAX register
Like the System V ABI the AACPS64 uses a special structure for
vararg handling. This is the first start to add this structure.
Handling in core.stdc.stdarg is missing!
