Hi Jack,
Been following your thread on GMP as well :). I tested gmp-4.2
(release) with --enable-cxx on a G5 (OS 10.3.9) machine, but compiled with
FSF's gcc-4.1.0 (fink-installed) using odcctools-590. For me, all but one
test in the entire test suite (run by make check) passes -- the one
failure being t-hamdist. Torbjorn has attributed that to a miscompile
(wrong-code) of mpz/hamdist.c. Haven't seen a gcc bug report on this yet
though.
I attempted to compile with Xcode's gcc (build 1640) on the same
machine, but it ICE'd on
../../mpz/cfdiv_q_2exp.c:91: internal compiler error: in extract_insn
I don't have a G5 machine with Xcode 2.x yet to test out
gcc-4.0.1 (build 5250). I'd be interested in hearing success/fail reports
with Xcode 2.
