Test suite regressions due to integer-gmp2
According to my performance builders, changeset:c774b28f/ghc (Phab:D82) caused prof-doc-fib and linker_unload to fail on both performance builders (Ubuntu 13.10 and Ubuntu 14.04):
Wrong exit code (expected 0 , actual 2 )
Stdout:
Stderr:
linker_unload: /home/nomeata/logs/ghc-tmp-REV/libraries/integer-gmp2/dist-install/build/libHSinteg_21cuTlnn00eFNd4GMrxOMi.a: unknown symbol `__gmpn_rshift'
linker_unload: resolveObjs failed
make[3]: *** [linker_unload] Error 1
*** unexpected failure for linker_unload(normal)and
Actual prof output differs from expected:

*** unexpected failure for prof-doc-fib(profasm)The former is also observed by SPJ. The latter actually looks less like a regression, and more an improvement – maybe Herbert simply did not run a profiled version when updating test results?
