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).

Fix for bug #67 (thanks to ggn for reporting!).
Turns out the tokenizer would not properly tokenize DOTx constructs
unless they were hanging off the end of a symbol. This should fix that
once and for all.

Removed naked 'abs' (sans leading dot) from mntab.
The problem with having .abs *and* abs (as an alternate) is that the
naked abs conflicts with the RISC asm instruction ABS R#. There's no
good way to detect this ahead time, and it's a bad idea to do so anyway.
So don't do it!

Fix for bug that happened when a called macro inside an if/endif block would have a syntax error: the assembler would get stuck in an infinite loop (Error: mismatched .endif)

Fixed a nasty bug that dropped symbols that shouldn't have been.
This stemmed from the fact that EQUR symbols somehow made it on to the
symbol declaration list. If such symbol was later .equrundef'd, it would
find it's way back onto the the sdecl list *twice*, with the result
that any symbols that came after it would be summarily discarded into
the ether. Really, really bad mojo.

Fix for bug #29.
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. :-)

Fixed word reversed fixup problem.
For some reason, there was code in several places that marked fixups/symbols
as belonging to a RISC section when it was clearly not the case. As a result,
it caused serious problems by reversing words in 68K sections just because a
symbol had been seen in a MOVEI # statement in a RISC section. Probably not
the last nasty surprise in this pile of spaghetti. :-/

Added "legacy mode" to assembler, which is on by default.
Apparently MAC did fixups for programmers who forgot that they couldn't
put a MOVEI immediately after a JUMP or JR, so we do the same to keep
legacy code assembling (though we may flip the default to OFF at some
time in the future :-P). If you don't like the assembler doing stuff like
that behind your back, you can tell it not to by adding the -n switch to
your command line.
There are lots of other cases that the user should be warned about with
RISC code; these will be added in future commits. :-)

Fixed subtle bug in expr().
Basically, expr() was looking at the token following the one it was
looking at and bypassing the longer parse path if it found an EOL token
there. Problem is, some tokens have follow on values and so can be
considered compound tokens. In this case, the EOL token codes to 101,
having a constant with a value of 101 will not evaluate correctly in
this case as the CONST token is a compound token.
The short of this is that making assumptions is BAD! Don't do it! It
WILL come around to bite you in the ass eventually, in the form of
subtle bugs that are difficult to chase down. Assume nothing!

Fixed .cargs problem, more code cleanup/fixup
Thanks to GroovyBee for reporting the .cargs problem! Also, pretty much
all of the remaining cruft coming from the misguided "GPU in Main" cult
has been removed. Never do in an assembler what you can do with either
macros or a good preprocessor!
Shamus Hammons [Tue, 12 Feb 2013 18:32:56 +0000 (12:32 -0600)]
First stab at removing cruft.
Removing all automatic code munging in the background by the RISC
compiler, including GPU in main idiocy. This means there are no more
built-in macros either. If you really needed this functionality, you can
put macros in your source code to do it. It doesn't belong in the guts
of the assembler.

Fixed compiler not checking for INCBIN in BSS sections.
Apparently the compiler did not care if an INCBIN happened in a BSS
section or not. Now the compiler cares and gives an error if you try to
do this terrible, terrible thing. :-D
