| Summary | 0000213: failure of tests/hard_coded/direct_arg_tags.m in asm_fast.par.gc | ||||||||
| Description | tests/hard_coded/direct_arg_tags.m is failing in asm_fast.par.gc on x86-64 / Linux machines. (I encountered the failure on goliath). The output contains what appear to be memory addresses, so I suspect some terms are not being deconstructed correctly. I originally noted the failure at -O5 --intermodule-optimization but it also occurs with just -O-1. This occurs on both the 11.07 branch and trunk. | ||||||||
| Additional Information | tests/hard_coded/typeclasses/func_default_mode_bug.m tests/hard-coded/construct_test.m are also failing; it is most probably the same bug. | ||||||||

I can't reproduce it on my own machine (x86-64). Are you sure the standard library and runtime are up-to-date in the asm_fast.par.gc grade? |
|
juliensf (administrator) 2011-08-29 13:29 |
Yes, they are up-to-date; I will try it on some other x86-64 machines here. Perhaps, it's specific to the version of the C compiler being used or something. |

That appears to be the case: goliath: gcc 4.1.3: doesn't work. apollo : gcc 4.4.5: works. I will check other versions of gcc. (I don't think maintaining support for gcc 4.1 is terribly important, if it's just that version that is not working then we should just bump the minimum version of gcc required for Mercury.) |

goofy: gcc 4.4.3; works. |

I assume it's no longer a problem. |

I've been testing asm_fast.gc.par.stseg recently and didn't see this test case failure. I'm using gcc-4.8 on x86_64 Linux. I was testing both the master and version-14_01-branch branches. |
