Thanks to the LOCALS directive, we do need to break compatibility to TASM at
one point after all. This is the rest we can reasonably change to get at least
through JWasm's first pass without errors while maintaining compatibility to
TASM.
Includes:
* the OPTION syntax to switch in and out of floating-point emulation mode
* REP CMPSB → REPE CMPSB
* Hacks for two 80-byte short jumps
* lack of support for floating-point stupidity ♥
as well as other issues that I covered in previous commits and overlooked in
some files.
(Damn, the other commit prepared for today is not getting done, why does IDA
have to be so terrible...!)
Anyway, here's a small consistency edit instead.
Once you've actually found the right syntax that makes the assembler just use
the default call type of the current memory model for both procedures (where
it's just "PROC" without anything else) and labels (where it's "LABEL PROC"),
these constants become completely unneccessary, even with TASM.
I guess this marks the final demystification of how segment declarations work
and how they are compiled. However, it only really makes sense for anything
outside the TEXT segment, like these floating-point functions. As long as the
slices aren't immediately next to each other, it would still be annoying to
have segment declarations inside of them, since we'd have to copy-paste these
declarations around every INCLUDE directive...
Finally - and there was indeed no way around switching to JWlink, as ALINK
v1.6 refuses to link the TH01 executables with a nondescript "Undefined base
seg" message once nec_fpinit.asm is included.
Well, we have to start reducing this mess somewhere. The actual reduced
initialization code I've been preparing still fails to compile, and the data
is shared with a number of other components anyway, so...
