Searching for good compiler sequences is certainly not a new idea. Most work that I know focuses on finding good sequences for a particular program. I think an interesting opportunity here would be to search for good sequences that generally work well for Haskell programs to replace the standard -O1, -O2 used by LLVM. I would think the code generated from GHC is different enough that we should be able to find standard sequences that we could use to replace the ones currently used by LLVM. > > - -- > brandon s. allbery [linux,solaris,freebsd,perl] [email protected] > system administrator [openafs,heimdal,too many hats] [email protected] > electrical and computer engineering, carnegie mellon university KF8NH > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v2.0.10 (Darwin) > Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ > > iEYEARECAAYFAkzUtdQACgkQIn7hlCsL25VG6ACeJ3sSXoI4YLbXW3KIFVMqKqdK > oTsAn23bxl0mvfdl3up69xM4qWPnklGj > =TXBk > -----END PGP SIGNATURE----- > _______________________________________________ > Glasgow-haskell-users mailing list > [email protected] > http://www.haskell.org/mailman/listinfo/glasgow-haskell-users > _______________________________________________ Glasgow-haskell-users mailing list [email protected] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
