Worry not, it's already broken. I've been unable to test the AIX/PPC JIT since ICU went in. The configuration for ICU (at least as of 2.6) supports only a 64-bit build, while aix/asm.s is 32-bit only (the linker claims the .o is corrupt if assembled with OBJECT_MODE=64). To get it working again, one of three things needs to happen: 1. ICU becomes optional again (please!). 2. PPC64 JIT code is written which can be morphed into POWER code. Transforming PPC32->POWER was mostly straightforward, so hopefully 64-bit will be as well. 3. ICU's configure starts to support 32-bit compiles. This might happen with 3.0/CVS already, but I haven't checked. 1 is necessary anyway, but it doesn't seem like a high priority. 2 is best in the long run, but requires somebody who knows more about PPC64 ASM than I do to get started. I don't know if 3 has any chance of happening upstream, but I doubt there's anybody working on Parrot who wants to deal with it. If somebody can help with one or more of these, I can try to get it going on AIX 4.3.3 once again. Adam
