I can't duplicate this any more. I've been updating to gmp-4.2.3. Now, I get a build error much earlier: checking for suffix of object files... configure: error: in `/test/gnu/gcc/objdi r/hppa64-hp-hpux11.11/libgcc': configure: error: cannot compute suffix of object files: cannot compile This may be the same bug as the one reported here: http://gcc.gnu.org/ml/gcc/2008-08/msg00500.html I have been experimenting with IRA: --- pa64-regs.h (revision 139820) +++ pa64-regs.h (working copy) @@ -235,12 +235,25 @@ {{0x00000000, 0x00000000}, /* NO_REGS */ \ {0x00000002, 0x00000000}, /* R1_REGS */ \ {0xfffffffe, 0x00000000}, /* GENERAL_REGS */ \ - {0x00000000, 0x00000000}, /* FPUPPER_REGS */ \ + {0x00000000, 0x00000000}, /* FPUPPER_REGS */ \ {0x00000000, 0x0fffffff}, /* FP_REGS */ \ {0xfffffffe, 0x0fffffff}, /* GENERAL_OR_FP_REGS */ \ {0x00000000, 0x10000000}, /* SHIFT_REGS */ \ {0xfffffffe, 0x1fffffff}} /* ALL_REGS */ +/* The following macro defines cover classes for Integrated Register + Allocator.
