* Modules: Utils and Data (#13009)Sylvain Henry2020-04-261-145/+0
| | | | | | | Update Haddock submodule Metric Increase: haddock.compiler
* Use ByteString to represent Cmm string literals (#16198)Sylvain Henry2019-01-311-1/+1
| | | | Also used ByteString in some other relevant places
* Rename literal constructorsSylvain Henry2018-11-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | In a previous patch we replaced some built-in literal constructors (MachInt, MachWord, etc.) with a single LitNumber constructor. In this patch we replace the `Mach` prefix of the remaining constructors with `Lit` for consistency (e.g., LitChar, LitLabel, etc.). Sadly the name `LitString` was already taken for a kind of FastString and it would become misleading to have both `LitStr` (literal constructor renamed after `MachStr`) and `LitString` (FastString variant). Hence this patch renames the FastString variant `PtrString` (which is more accurate) and the literal string constructor now uses the least surprising `LitString` name. Both `Literal` and `LitString/PtrString` have recently seen breaking changes so doing this kind of renaming now shouldn't harm much.

* Refactor LitStringSylvain Henry2018-05-131-3/+30
| | | | | | | | | | | | | | | | | | Refactor LitString so that the string length is computed at most once and then stored. Also remove strlen and memcmp wrappers (it seems like they were a workaround for a very old GCC when using -fvia-C). Bumps haddock submodule.

* compiler: introduce custom "GhcPrelude" PreludeHerbert Valerio Riedel2017-09-191-0/+2
| | | | | | | | | | | | | | | | | | This switches the compiler/ component to get compiled with -XNoImplicitPrelude and a `import GhcPrelude` is inserted in all modules. This is motivated by the upcoming "Prelude" re-export of `Semigroup((<>))` which would cause lots of name clashes in every modulewhich imports also `Outputable` Reviewers: austin, goldfire, bgamari, alanz, simonmar Reviewed By: bgamari Subscribers: goldfire, rwbarton, thomie, mpickering, bgamari Differential Revision: https://phabricator.haskell.org/D3989
* Remove some `undefined`sÖmer Sinan Ağacan2016-06-271-3/+2
| | | | | | These get annoying when `undefined` is actually used as placeholder in WIP code. Some of these were also completely redundant (just call `deAnnotate'` instead of `deAnnotate` etc.).
* Pretty: use BangPatterns instead of manual unboxing Ints (#10735)Thomas Miedema2015-08-051-5/+3
| | | | | | | Follow same style as libraries/pretty, although some of it is pretty archaic, and could be improved with BangPatterns: * `get w _ | w == 0 && False = undefined` * `mkNest k _ | k `seq` False = undefined`
* Replace `STRICT[12345]` macros by `BangPatterns`Yuri de Wit2014-11-251-17/+3
| | | | | | | | | | This removes the macros `STRICT1()`, `STRICT2()`, `STRICT3()`, `STRICT4()`, and `STRICT5()` CPP macros from `HsVersions.hs` and replaces the few use sites by uses of `BangPatterns`. Reviewed By: hvr Differential Revision: https://phabricator.haskell.org/D525

* Add LANGUAGE pragmas to compiler/ source filesHerbert Valerio Riedel2014-05-151-1/+3
| | | | | | | | | | | | | | | | | | In some cases, the layout of the LANGUAGE/OPTIONS_GHC lines has been reorganized, while following the convention, to - place `{-# LANGUAGE #-}` pragmas at the top of the source file, before any `{-# OPTIONS_GHC #-}`-lines. - Moreover, if the list of language extensions fit into a single `{-# LANGUAGE ... -#}`-line (shorter than 80 characters), keep it on one line. Otherwise split into `{-# LANGUAGE ... -#}`-lines for each individual language extension. In both cases, try to keep the enumeration alphabetically ordered. (The latter layout is preferable as it's more diff-friendly) While at it, this also replaces obsolete `{-# OPTIONS ... #-}` pragma occurences by `{-# OPTIONS_GHC ... #-}` pragmas.

* Rename remaining FastBytes usages to ByteStringIan Lynagh2012-12-141-4/+1

* Make FastBytes a synonym for ByteStringIan Lynagh2012-12-131-2/+1
| | | | | | | | | | | A step on the way to getting rid of FastBytes slow nofib Compile times look like: -1 s.d. -2.4% +1 s.d. +3.4% Average +0.4% but looking at the times for the longer-running compilations I think the change is just noise.
* Use ByteString rather than FastBytes inside FastZStringIan Lynagh2012-12-121-11/+20
| | | | | | | Slow nofib Compile Times difference looks like just noise: -1 s.d. -2.9% +1 s.d. +2.9% Average -0.1%
* Add a separate FastZString typeIan Lynagh2012-07-151-2/+9
| | | | | | | | | FastStrings are now always UTF8-encoded. There's no StringTable for FastZString, but I don't think one is needed. We only ever make a FastZString by running zEncodeFS on a FastString, and the FastStrings are shared via the FastString StringTable, so we get the same FastZString from the IORef.
* Use -fwarn-tabs when validatingIan Lynagh2011-11-041-0/+7
| | | | | We only use it for "compiler" sources, i.e. not for libraries. Many modules have a -fno-warn-tabs kludge for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | re-recording to avoid new conflicts was too hard, so I just put it all in one big patch :-( (besides, some of the changes depended on each other.) Here are what the component patches were: Fri Dec 28 11:02:55 EST 2007 Isaac Dupree <id@isaac.cedarswampstudios.org> * document BreakArray better Fri Dec 28 11:39:22 EST 2007 Isaac Dupree <id@isaac.cedarswampstudios.org> * properly ifdef BreakArray for GHCI Fri Jan 4 13:50:41 EST 2008 Isaac Dupree <id@isaac.cedarswampstudios.org> * change ifs on __GLASGOW_HASKELL__ to account for... (#1405) for it not being defined. I assume it being undefined implies a compiler with relatively modern libraries but without most unportable glasgow extensions.

* Reorganisation of the source treeSimon Marlow2006-04-071-0/+124
Most of the other users of the fptools build system have migrated to Cabal, and with the move to darcs we can now flatten the source tree without losing history, so here goes. The main change is that the ghc/ subdir is gone, and most of what it contained is now at the top level. The build system now makes no pretense at being multi-project, it is just the GHC build system. No doubt this will break many things, and there will be a period of instability while we fix the dependencies. A straightforward build should work, but I haven't yet fixed binary/source distributions. Changes to the Building Guide will follow, too.
