For powerpc-darwin9, there are a couple of issues which I've hacked around to get bootstrap to complete. 1. In rs6000.h Where there are TARGET_XXX macros set to zero and guarded by config-time HAVE_AS_YYY (e.g. TARGET_POPCNTD, HAVE_AS_POPCNTD) This causes an error when the #define TARGET_POPCNTD OPTION_POPCNTD is parsed. For the sake of making progress, I just worked around these by moving the guarded defines to where the OPTION_XXXs are equated -- I.E: #ifndef HAVE_AS_XXX #define TARGET_XXX 0 #else #define TARGET_XXX OPTION_XXX #endif likely, that's not the Right Solution, but it allowed me to get to the next step - 2. rs6000_misc_flags{,explicit} and rs6000_debug_flags{,explicit} are declared as HOST_WIDE_INT which is 'long long' for this target. This causes fails on lines 1841, 1842, 1844 and 1846 in rs6000.c because of mismatched format specifier and argument. I just worked around this with a temporary definition of a suitable format descriptor. With these two hacks, bootstrap completes for all langs including Java, Ada and ObjC++. I haven't done any formal reg-tests yet, but a selection of checks across the board look reasonable so far. If there is any other specific input that would be useful let me know - these older platforms are somewhat slow for the full build/test cycle. cheers Iain
