Hey All, i've opened a ticket for this build problem http://hackage.haskell.org/trac/ghc/ticket/7874 ghc seems to build successful when i do quick, but not quick-llvm. Which seems worrisome maybe? was with current ghc head, commit hash 2fa44a8ab9d6c68c14ccb25ac26a556d1d82d70d any thoughts would be appreciated on what could be the culprit and how i can track it down / help fix it. thanks -Carter heres's the results of my make test run OVERALL SUMMARY for test run started at Tue Apr 30 16:06:51 EDT 2013 3628 total tests, which gave rise to 14337 test cases, of which 11044 were skipped 28 had missing libraries 3182 expected passes 56 expected failures 3 caused framework failures 2 unexpected passes 22 unexpected failures Unexpected passes: driver T5313 (normal) perf/should_run T149 (normal) Unexpected failures: codeGen/should_run cgrun071 [bad exit code] (normal) driver T2507 [bad stderr] (normal) ghc-api/T7478 T7478 [bad exit code] (normal) perf/compiler T1969 [stat not good enough] (normal) perf/compiler T3064 [stat not good enough] (normal) perf/compiler T3294 [stat not good enough] (normal) perf/compiler T4801 [stat not good enough] (normal) perf/compiler T5030 [stat not good enough] (normal) perf/compiler T5321FD [stat not good enough] (normal) perf/compiler T5321Fun [stat not good enough] (normal) perf/compiler T5631 [stat not good enough] (normal) perf/compiler T5642 [stat not good enough] (normal) perf/compiler T5837 [stat not good enough] (normal) perf/compiler T6048 [stat not good enough] (optasm) perf/compiler T783 [stat not good enough] (normal) perf/compiler parsing001 [stat not good enough] (normal) perf/should_run T4474a [stat not good enough] (normal) perf/should_run T4474b [stat not good enough] (normal) perf/should_run T4474c [stat not good enough] (normal) simplCore/should_compile T4908 [stderr mismatch] (optasm) simplCore/should_compile T7360 [stderr mismatch] (optasm) simplCore/should_compile spec-inline [stderr mismatch] (optasm)
