The only thing I've managed to run so far is the standard "make all". What's mysterious though is that if I grab a clean copy from the trunk, it builds fine. However, if I do "make clean" first, that error appears. Does anyone else get this? (I'm using Ubuntu and compiling on x86_64)
I managed to get an assembly dump of system.pp and compare the output between ppc1, ppc2 and ppc3. Some procedures in ppc3 look very different, as if compiled by an older version of the compiler. It's confusing, but I'll keep at it. I don't want to scrap my changes, because so far I've managed to make -O3 about 15% faster. Gareth aka.
