In [changeset:"a72614c40186521da7ba090b102436e61a80b7a7/ghc"]: {{{ #!CommitTicketReference repository="ghc" revision="a72614c40186521da7ba090b102436e61a80b7a7" Make T8832 operative on 32-bit systems (#8832)
(Also, the 'extra_clean' was unnecessary.) }}}
Btw, now that I saw that commit, I've seen other testcases making use of the pre-defined `SIZEOF_HSWORD` (and there's also `WORD_SIZE_IN_BITS`) CPP symbol to test for wordsize. Would that have worked as well? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8832#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
