Rasm Z80 assembler

[roudoudou]

update v071
- math functions HI & LO to get high 8 bits or low 8 bits of a pseudo 16 bits value
- @ prefix for octal values
- AS80 assembler compatibility mode* (enough to compile CNG player with the same wrong calculations  )








short doc

-ass   AS80 behaviour mimic

   
• all calculations are done with 32 bits integer values and wrong rounding
• macro parameters are not protected with {} anymore
• multiple declarations with DEFB,DEFW,DEFI got reference adress of the first outputed byte. That's why with AS80, using multiple DEFB produces a different result than using DEFB with multiple values
• MACRO declaration directive must be used after the macro name

Cool! Thanks!

update v0.72
- ability to generate snapshot v2 (useful with M4Wifi)

BUILDSNA V2

Hi,

Now I feel dumb, I can not get the program to run. I just see the command prompt window to open in a fraction of a second, not able to read what it says, and that's it.

It is a command line tool.
Open a terminal and run

update v0.73
- bugfix in snapshot when using distinct banks instead of gathering them with bankset directive

[roudoudou]

quick update v0.74
- usage of snapshot directives forces snapshot output
- try to load .asm or .Z80 file if filename given is not found and has no extension
- BREAKPOINT directive may have an additional parameter to set break adress anywhere
- declaring two MACRO with the same name will trigger an error
- bugfix regression of -m option handling
- each REPEAT or WHILE loop export a REPEAT_COUNTER or WHILE_COUNTER variable, locally

[roudoudou]

update v0.75
- newer and faster expression calculator without limitations of comparisons
- % may be used as modulo (still used for binary values)
- Intel hexa & binary style support
- Binary prefix 0b fixed
- does not export IX and IY anymore in symbol files
- better error messages when calculating expressions
- boolean operators && and ||
- PUSH & POP may have more than one register in parameters
- NOP may be multiplied specifying a number of repetition in parameter
- alias <> for != comparison operator
- filenames are forced to upper case when saved to EDSK
- Infinite loop detection won't go to infinite loop anymore ^_^

As the solver is very different from the previous version, i keep the 0.74 version available, in case of regression

Now i have to work on the documentation, again 

[GUNHED]

Another big update! Thank you!


It's great to have a French manual (mother tongue is always the best). But please also update the English manual if needed (still shows 0.72, not 0.75, but maybe it need no update - I have to find out :-))


Keep the great work going!!! 

[roudoudou]

I have to work on english version too before updating here

[GUNHED]

Yeah, I know, and making docs and manuals is just no fun.    But if you come to an end (or close to an end) I would like to make a translation to German language for you.    Just let me know when "final" stage is in sight 

[roudoudou]

update v0.76
- fix solver when using % prefixed binary values close to comparison operator or parenthesis

Both FR & EN doc updated 

[roudoudou]

quick update for maxam compatibility mode users
update v0.77
- even faster expression calculation
- maxam & AS80 comparison operators are back

[roudoudou]

ultra-light but requested update v0.78
- DEFS can handle multiple repetition schemas
- alias DM & DEFM for DEFB

[roudoudou]

update v0.79
- != operator is back with new solver 

[roudoudou]

update v0.80

- bugfix operator > and >=
- bugfix Maxam priorities

[roudoudou]

update v0.81
- added special maxam priorities for parenthesis and boolean operators




The priority management in maxam compatibility mode is less trivial than it seems to be 

[Golem13]

Fixes are validated coz 0.81 is working fine for me.
Thanks Roudoudou 

[GUNHED]

Yes, 81 seems to be a good number. Everything stable and well here too.

I have another version pending 
With 'while 0 bugfix' but nothing really important

[roudoudou]

Due to my system upgrade (a 6 years old ubuntu LTS to the new Lubuntu beta LTS) i remove many compilation warnings. CLang compilation takes ages but the performance of the executable is noticable (30% faster)

- I added also SL1 alias for SLL
- better infinite loop detection (i mean, safer)
- bugfix while 0 loop (check and disable block)
- repeat until internal counter harmonisation (now they are all starting from value 1)

[roudoudou]

update v0.83
- NOCODE output must increment current adress in all cases
- new directives DR & DEFR to define REAL values (Amstrad firmware compatible)

I just learned (at the Revision, from Offset) that Basic has an integer division, with the symbol \ (or ç on French keyboard). I already reported you that the "accurate" division was a bit problematic in some cases. Do you think something similar could be implemented?

Using INT() must solve the case

[roudoudou]

You may be interrested also by the floor() function, the result is again different in another way


Example:

Code Select Expand



a=10
b=2
repeat 10
print a,"/",b," normal=",a/b," int()=",int(a/b)," floor()=",floor(a/b)
b=b+1
rend



Will produce
