Hello,
I'm currently hacking on a small linker for 16Bit NE executables.
My current main issue is that clang doesn't seem to support the 16Bit calling
convention 'pascal' properly.
Consider the following code sample:
########
static void __pascal test2(short s1, short s2, short s3, short s4)
{
}
test2(1, 2, 3, 4);
########
That compiles to
########
mov DWORD PTR [esp],0x1
mov DWORD PTR [esp+0x4],0x2
mov DWORD PTR [esp+0x8],0x3
mov DWORD PTR [esp+0xc],0x4
mov DWORD PTR [esp+0x10],eax
call 120 <test2>
########
AFAIK __pascal should push the arguments in the other order, and not as 4
bytes each. OpenWatcom, that generates real 16Bit code, pushes only 2 byte
each.
Is there away to get fake 16Bit code generated that follows that calling
convention so interfacing with real 16Bit code is possible?
Regards,
Fabian Maurer
