nmlgc bbd8ff96ab [Reduction] #563-568: Floating-point emulator initialization 
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.

nmlgc ae6c844b25 Ensure the correct amount of padding between the TEXTC and DSEG segments 
Since DSEG is *supposed* to be aligned to a paragraph boundary, this should
have never mattered. However, JWlink seems to not obey this segment alignment
in some layer of the linking process.
This now guarantees identical builds with TLINK, ALINK and JWlink.

nmlgc 4ac17ac2a5 Trick TASM into not creating 32-bit default segments 
So that's the - admittedly rather weird - solution to the problem that has
been plaguing this project ever since the beginning of the reduction step.
Without any 32-bit dummy segments in the compiled object files, more linkers
will be able to build this project, one of them being JWlink
(http://sourceforge.net/projects/jwlink/).

Still can't rename dseg to _DATA though, as TASM stupidly refuses to accept
any ALIGN directives above a segment's alignment attribute value. TH01's
floating-point data slices already require larger alignments, and we're very
likely to have even more of those in the future.

Also, we're finally defining the Borland C++ model symbols directly in the
code, rather than in my unpublished build batch files. :)

Also finally getting a macro for the recurring "pop cx if LDATA" case.

nmlgc 696d7f9476 Identify the missing BSS slice of xxv.cpp 
sigdata.c doesn't specify any alignment, so this is the only position that
makes sense.

nmlgc 340c8a792a General cleanup 
Mostly moving spurious null bytes, which are actually supposed to denote
alignment, into their associated slices, but also prettying up some of the
very first slices.

nmlgc 1c72d7e242 [Reduction] #548: Floating-point emulation data 
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...

More flags and constants, despite reminding me why exactly I haven't done this

nmlgc 658ed9e72b Move "Abnormal program termination" to its own slice 
That was the very first function reduced, before I came up with the data slice
model in 59688e23fc.

There's also the PC-98-specific nec_delay. Which means that the inclusion of
this function into the games was *ding* entirely pointless.

Man, compilers sucked in the early 90s.

nmlgc 00e2dcb519 Remove comments containing garbage characters 
... as well as other useless comments that were in close proximity to those.
Now, all files should be valid Shift-JIS.
 2014-09-18 20:41:06 +02:00
nmlgc 1e991fbec0 Remove automatically generated line breaks in string constants 
Especially annoying if that happens in the middle of a Shift-JIS multi-byte
sequence, like in those two instances in TH02's OP.EXE. Also, making up for
the lack of string analysis during the dumping process of TH05's MAIN.EXE.
