is it true, that there is an assembler built into os x? i bought and iBook and so i just got the os not the developers cd. if there is one, is it built into the os or is it on the dev cd?
if it is on the developer cd, is there any way to get it somwhere without having to d/l the 130megs package?
thx

Just on the Dev CD, AFAIK.

I used to do some development in assembly language on x86.Anyone got some links for starting out with osx and ppc ?

Yes, the assembler is on the DevTools, and you'll need the tools anyway because you'll probably want a linker too.
You do already ahve the tools, in /Applications/Installers. However they may not be up-to-date -- you'll probably want the December 2002 Tools if you can get them.

The DevTools come with quite a bit of documentation, including PPC Assembly.

Heh, that's great! I've dug all over the net looking for docs on PPC ASM and I had 'em on my harddrive the whole time. Nice...
Thanks for the tip!

Motorola, IBM, and the makers of Fantasm offer quite a bit of documentation on the PPC instruction set. OSX uses the PowerOpen ABI. If you're coming from an x86 background, prepare for a shock. RISC assembly is at least an order of magnitude more tedius than x86 assembly.
I found this document to be pretty useful. (It's not just for compiler authors)
PowerPC Compiler Writer's Guide
You'll have to ignore a lot of things that are specific to OS 9 and things that are specific to their assembler, but there is alot of good stuff at http://www.lightsoft.co.uk/. One of the authors has written some pretty decent articles about PPC assembly programming. I learned a method of converting unsigned short to float from him that puts the code generated by gcc to shame.
