Re: Preprocessing Assembly

[Johann Oskarsson <myrkraverk@users.sourceforge.net>]

Hi,

MASP can now be found on the web: 
http://cosmos.raunvis.hi.is/~johannos/masp/
This is just a trial version so far.  The only changes are that 
directives now start with \ instead of ., so this no longer conflicts 
with the underlying assembler.  And mips directives in particular.  I've 
yet to add a command line parameter to change this char, but it can be 
done easily.

I'll try to fix this one day, don't know if it'll be soon though.

I've changed the base syntax in masp, it now uses 0[bhqd]<number> for 
strange bases instead of the ugly [BHQD]'<number> syntax.  Although I 
haven't released that version yet, I can do so now and/or emailed it if 
anyone asks.  This also means that 'c' character constants can now be 
passed to the assembler.

I'm not sure if/when I can address this, most of the changes I make, is 
to fix something that simply pisses me off!

I haven't had a close look on the F4 but I will perhaps in the future.

P.S. You've mentioned a lot of stuff, and I wish I could fix them all 
but I'm still familiarizing myself with the code and capabilities of 
gasp.  I can perhaps do more if you try masp and send me some bug reports.
