* FastString: Reduce allocations of concatFSBen Gamari2016-07-081-1/+1
| | | | | Instead of unpacking and then repacking we simply concatenate all of the individual ByteStrings.
* Remove 'deriving Typeable' statementsRyan Scott2016-05-241-2/+2
| | | | | | | | | | | | | | | | | Summary: Deriving `Typeable` has been a no-op since GHC 7.10, and now that we require 7.10+ to build GHC, we can remove all the redundant `deriving Typeable` statements in GHC.

* Drop pre-AMP compatibility CPP conditionalsHerbert Valerio Riedel2015-12-311-4/+0
| | | | | | | | | | | | Since GHC 8.1/8.2 only needs to be bootstrap-able by GHC 7.10 and GHC 8.0 (and GHC 8.2), we can now finally drop all that pre-AMP compatibility CPP-mess for good!

* Refactor: delete most of the module FastTypesThomas Miedema2015-08-211-36/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverses some of the work done in #1405, and goes back to the assumption that the bootstrap compiler understands GHC-haskell. 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
