First of all, if you're stupid and say: | | ghc ... -fmax-simplifier-iterations=5 | | then ghc crashes with: | | ghc-5.05: panic! (the `impossible' happened, GHC version 5.05): | Prelude.read: no parse | | Please report it as a compiler bug to [EMAIL PROTECTED], | or http://sourceforge.net/projects/ghc/. | | (same thing happens in 5.04.2) | | I think in DriverFlags.hs, the command for max-simpl... should be changed | from: | | Prefix (writeIORef v_MaxSimplifierIterations . read) | | to | | PrefixPred (all isDigit) (writeIORef v_MaxSimplifierIterations . read) | | Now, more importantly, it seems to obey this command unless you give it, | for instance, 0 as an argument: | | ghc ... -v5 -fmax-simplifier-iterations0 | grep 'Simplifier' | | | yields: | | ==================== Simplifier phase 0, iteration 1 out of 0 | ==================== | ==================== Simplifier phase 0, iteration 1 out of 0 | ==================== | ==================== Simplifier phase 0, iteration 2 out of 0 | ==================== | ==================== Simplifier phase 0, iteration 2 out of 0 | ==================== | | | which seems pretty bad to me :) | | - Hal | | | -- | Hal Daume III | | "Computer science is no more about computers | [EMAIL PROTECTED] | than astronomy is about telescopes." -Dijkstra | www.isi.edu/~hdaume | | _______________________________________________ | Glasgow-haskell-bugs mailing list | [EMAIL PROTECTED] | http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs _______________________________________________ Glasgow-haskell-bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
