- Fixed LLVM style CL args for D2. - Moved main() into its own file gen/main.cpp - Fixed basic cross compilation - removed the option for setting OS - added support for llc's mattr, mcpu and mtriple switches - added basic ABI abstraction for return value rewrites, it's not perfect and will probably be completely rewritten once I get to handling parameter rewrites as well. - x86-64 extern(C) abi for cfloat returns now match (llvm-)gcc.

module bug80;
extern(C) int printf(char*, ...);

void main()
{
    byte b = 10;
    int i = b += 2;
    printf("byte=%d int=%d\n", b, i);
    assert(b == 12);
    assert(i == 12);
}
