In particular: * use MagicHash instead of _ILIT and _CLIT * pattern matching on I# if possible, instead of using iUnbox unnecessarily * use Int#/Char#/Addr# instead of the following type synonyms: - type FastInt = Int# - type FastChar = Char# - type FastPtr a = Addr# * inline the following functions: - iBox = I# - cBox = C# - fastChr = chr# - fastOrd = ord# - eqFastChar = eqChar# - shiftLFastInt = uncheckedIShiftL# - shiftR_FastInt = uncheckedIShiftRL# - shiftRLFastInt = uncheckedIShiftRL# * delete the following unused functions: - minFastInt - maxFastInt - uncheckedIShiftRA# - castFastPtr - panicDocFastInt and pprPanicFastInt * rename panicFastInt back to panic# These functions remain, since they actually do something: * iUnbox * bitAndFastInt * bitOrFastInt Test Plan: validate Reviewers: austin, bgamari Subscribers: rwbarton Differential Revision: https://phabricator.haskell.org/D1141 GHC Trac Issues: #1405 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/1405#comment:22> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
