Hey all, Some mips64 and gmp observations: The normal way, unregisterised, with the in-tree gmp, v3.1.1: OVERALL SUMMARY for test run started at Fri Oct 24 17:17:56 PDT 2003 1070 total tests, which gave rise to 1070 test cases, of which 0 caused framework failures 29 were skipped 889 expected passes 10 expected failures 0 unexpected passes 142 unexpected failures ^^^^^ When I recompiled using the Irix-provided libgmp, also v3.1.1, the results were: OVERALL SUMMARY for test run started at Sat Oct 25 20:13:03 PDT 2003 1070 total tests, which gave rise to 1070 test cases, of which 0 caused framework failures 29 were skipped 932 expected passes 10 expected failures 0 unexpected passes 99 unexpected failures ^^^^^ 43 tests, involving floats or double, passed with the external libgmp. The brokeness exhibited itself as segfaults, or showing values as 0.0 or 0.0e0 instead of the correct result. These tests that were cured by using an external gmp: arr0{05,06,13,16} num0{01,07,08,11} cg0{14,18,19,24,26,28,34,35,42} arith0{01,04,06-08,12-14,16-17} CPUTime001 gshow gzip paradise strings timeexts001 rand001 dynamic001 mdo001 andy_cherry barton-mangler-bug cholewo-eval fun_insts jl_defaults lennart_range thurston-modular-arith tcrun027 So mips64 users should definitely use the external gmp provided with Irix, as it must be better configured than ours for the time being. And, I guess all porters should take note that even though a port builds, and can then rebuild ghc itself, it may still be broken in ways only the testsuite will find. Cheers, Don
