[ANNOUNCE] Another Trivia Language: URM
Hi, I'd like to add one more to the library of trivia languages. It is not as strange as Bf or Ook! and it is actually a real (teaching) language. Enter: URM URM is a "language" at least used in German universities to teach the basic principles of programming. URM stands for Universal Register Machine - it basically means that you have a couple of operations and an unlimited amount of registers to use for your programs. Here are the URLs More information: http://perl.thiesenweb.de/readme-urm.txt My initial package: http://perl.thiesenweb.de/urmc-0.1.tar.bz2 Have fun Marcus -- - |Marcus Thiesen ICQ# 108989768| - | www.thiesenweb.de | - 28A7 37CC AE2C BB6C D56D 8A3D E614 E56B 7546 75F2 signature.asc Description: This is a digitally signed message part

(i.e. no hardcoded "parrot" executable, no "rm", ... just C, assuming the destination languages/urm) - a "make test" target would be nice - IIRC the license GPL should be ok for languages > http://perl.thiesenweb.de/urmc-0.1.tar.bz2 > Have fun > Marcus Always, thanks leo

The register allocator starts to allocate registers from 16..31 first, so that only the top halve of one register bank has to be preserved over function calls. If your language doesn't provide subroutines you can safely ignore this. Further: as URM has an arbitrary amount of registers, it would be much simpler to target PIR code. r46 <- r100 + r200 is currently for sure an error. OTOH translating this to $I46 = $I100 + $I200 is fine. And finally: Please emit an "end" statement at the end of your code (i.e. when branching to a non existent label) or things will break especially when running with the JIT core. leo

I've not rewritten the Makefiles because all the other languages/ Makefiles are either created by the parrot config or are really hardcoded Unix makefiles. Still have some open issues, but I believe it is enough for version 0.2 http://perl.thiesenweb.de/urmc-0.2.tar.bz2 Have fun, Marcus -- - |Marcus Thiesen ICQ# 108989768| - | www.thiesenweb.de | - 28A7 37CC AE2C BB6C D56D 8A3D E614 E56B 7546 75F2 signature.asc Description: This is a digitally signed message part

Now I have my own register management and put all the not needed registers on the user stack. Why? Parrot with the PIR assembler can handle an arbitrary register count. I'm sure you are not able to write a program (doing something useful) to force imc to spill registers :) I've not rewritten the Makefiles because all the other languages/ Makefiles are either created by the parrot config or are really hardcoded Unix makefiles. The latter is a bug of course. Anyway - if possible - put urm in languages/urm, create confige/gen/makefiles/urm.in, adapt makefiles.pl, run Configure, use Parrot:Config, replace hardcoded 'parrot' with config vars and try to get it running. If this step is too big (or you don't know, what I' talking about :), just drop me a mail, I'll have a look at it then. For the tests (thanks) you might consider reading "perldoc Test::Simple" and alike - BTW & apropos: met Michael G Schwern and David Hand yesterday at the Vienna.pm TechMeet http://use.perl.org/~maks/journal/14901 Have fun, Marcus Thanks, leo

It's far to easy to use imc and I wanted the challenge. > The latter is a bug of course.

I know what you're talking about. I'll try to do so in a minute. > For the tests (thanks) you might consider reading "perldoc Test::Simple" > and alike - Jea, but I always feel strange using perl test tools for non perl stuff like a compiler and it's output.
