There's still a ways to go before this will work properly as we need to
add proper fixup handling and origin (".org") bookkeeping. As it is now,
the addition of all the miscellaneous bits and bobs to support the main
56K assembler are in place but they don't cause any regressions to the
existing assemblers already present in RMAC. Stay tuned for Round 2!
Some of the following changes are ggn's, and some are mine:
- When tokenizing floats we need to store them using a double pointer
- PTR union needed a (double *)
- Major changes to float depositing in eagen0.c
- Reverted the changes in expr.c so at least floats are processed by
expr() and friends
- SYM svalue needs to be 64 bits
- When EQUing a float symbol don't chop off the upper 32 bits from eval
- Added fltpoint.{c,h} in order to properly create IEEE-754 floating
point and Motorola extended numbers
- Fixed float evaluations in evexpr()
- Fixed floating point depositions in direct.c (in d_dc())
- Upped the BSD image limit in object.c to 8MB for crazy people making
6MB Jaguar ROMs (will need a real fix at some point)
- Source fixed to work with current rmac implementation
- Removed ultra kludgy output mode and replaced it with .com/.exe./.xex output module (activated using -fx)
- Added #< and #> to give low and high bytes off an immediate word
- Included tester in "tests" folder.
- Updated docs.
ggn deserves most of the credit for this, as my job was going through
and tossing out the stuff that wasn't needed. ;-) There might be some
ELFish things that still need fixing; time, as usual, will tell.
This probably won't help on Visual Studio, unless you can tell the build
system there to use a C99 compliant compiler (MS's track record in this
area is abysmal).
Whoever put this stuff together made a HUGE mistake in its alignment
pseudo-ops. Basically, before this fix, alignment directives in a RISC
section had absolutely NO guarantees of efficacy. This is what happens
when you bodge things together without extensive testing! Note that if
you had some RISC code that you had to wave a dead chicken at to get it
to work, it will probably not work any longer as the assembler will now
do what you tell it to. ;-)
This is a big enough change that it merits a minor version bump; we're
now at 1.3.0. :-)
