Hi,
I have tried the real mode FPC (PP16), but unfortunately it cannot handle
32bit code in inline assembly properly.
E.g.
mov eax,dword ptr [reax]
becomes
mov ecx,word [bp-4]
in the intermediate assembly file so you get an
error: mismatch in operand sizes
from the compiler.
So you can compile the source only with the same ' dumb opcode overrides'
and the source level elegancy advantage disappears this way.
But you are right, the 32bit fpc compiler can be used. I have uploaded the
modified package with fp32 source code. The package also contains the
compiled protected mode binary (sstepp.exe) that is prelinked with ring0
stub CWSDSTR0.
