* Put Unique related global variables in the RTS (#19940)Sylvain Henry2021-06-051-0/+6

* Implement Unique supply with Addr# atomic primopSylvain Henry2021-01-051-27/+5
| | | | | | | | Before this patch the compiler depended on the RTS way (threaded or not) to use atomic incrementation or not. This is wrong because the RTS is supposed to be switchable at link time, without recompilation. Now we always use atomic incrementation of the unique counter.
* Module hierarchy: ByteCode and Runtime (cf #13009)Sylvain Henry2020-02-121-0/+15

* Minor refactor in ghc.cabal.in:Ömer Sinan Ağacan2019-12-261-0/+24
| | | | | | - Remove outdated comments - Move cutils.c from parser to cbits - Remove unused cutils.h

* Clean up `#include`s in the compilerJohn Ericson2019-10-051-1/+1
| | | | | | | | - Remove unneeded ones - Use <..> for inter-package. Besides general clean up, helps distinguish between the RTS we link against vs the RTS we compile for.
* unique: fix UNIQUE_BITS crosscompilation (Trac #13491)Sergei Trofimovich2017-03-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #13491 manifests best when we try to crosscompile from 32-bit (i386-linux) to 64-bit (powerpc64-linux) system: ./configure --target=powerpc64-unknown-linux-gnu The build fails at assembly time: "inplace/bin/ghc-stage1" ... -c rts/StgStartup.cmm /tmp/ghc19687_0/ghc_4.s: Assembler messages: /tmp/ghc19687_0/ghc_4.s:11:0: error: Error: unknown pseudo-op: `.l' | 11 | .L<\x00>4: | ^ That happens because UNIQUE_BITS is defined in terms of WORD_SIZE_IN_BITS macro: #define UNIQUE_BITS (WORD_SIZE_IN_BITS - 8) WORD_SIZE_IN_BITS is 64 bits (equals to target value) while ghc-stage1 is still running on i386-linux The fix is to stop relying on target macros and use host's 'sizeof (HsInt)' and 'finiteBitSize' way to determine unique layout.

* UniqSupply: Use full range of machine wordBen Gamari2016-12-151-4/+21
| | | | | | | | | | | | | | | | | | | | | | Currently uniques are 32-bits wide. 8 of these bits are for the unique class, leaving only 24 for the unique number itself. This seems dangerously small for a large project. Let's use the full range of the native machine word. We also add (now largely unnecessary) overflow check to ensure that the unique number doesn't overflow.

* compiler/iface: compress .hi filesAustin Seipp2016-05-212-0/+1884
| | | | | | | | | | | | | | | | | | | Compress all interface files generated by the compiler with LZ4. While being only a tiny amount of code, LZ4 is both fast at compression and decompression, and has good compression ratios. Non-scientific size test: size of stage2 compiler .hi files: `find ./compiler/stage2 -type f -iname '*.hi' -exec du -ch {} + | grep total$` Without this patch: 22MB of .hi files for stage2. With this patch: 9.2MB of .hi files for stage2. Signed-off-by: Austin Seipp <austin@well-typed.com> Reviewed By: bgamari Differential Revision: https://phabricator.haskell.org/D1159
* Make it possible to have different UniqSupply strategiesBartosz Nitka2015-10-271-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To get reproducible/deterministic builds, the way that the Uniques are assigned shouldn't matter. This allows to test for that. It add 2 new flags: * `-dinitial-unique` * `-dunique-increment` And by varying these you can get interesting effects: * `-dinitial-unique=0 -dunique-increment 1` - current sequential UniqSupply * `-dinitial-unique=16777215 -dunique-increment -1` - UniqSupply that generates in decreasing order * `-dinitial-unique=1 -dunique-increment PRIME` - where PRIME big enough to overflow often - nonsequential order I haven't proven the usefullness of the last one yet and it's the reason why we have to mask the bits with `0xFFFFFF` in `genSym`, so I can remove it if it becomes contentious.

* Fix bootstrapping of GHC with earlier versionsPatrick Palka2013-09-041-0/+4
| | | | | | | | We can no longer use atomic_inc() in the stage1 compiler because its prototype was recently changed. Since the stage1 compiler is always single-threaded, only use atomic_inc() when THREADED_RTS is defined.
* genSym: atomic_inc() now takes two argumentsPatrick Palka2013-09-041-1/+1

* UniqSupply: make mkSplitUniqSupply thread-safePatrick Palka2013-08-261-1/+5
| | | | | | | | | | | | | unsafeInterleaveIO is used instead of unsafeDupableInterleaveIO because a mk_supply thunk that is simultaneously entered by two threads should evaluate to the same UniqSupply. The UniqSupply counter is now incremented atomically using the RTS's atomic_inc(). To mitigate the extra overhead of unsafeInterleaveIO in the single-threaded compiler, noDuplicate# is changed to exit early when n_capabilities == 1.
* Move the genSym stuff from rts into compilerIan Lynagh2013-05-171-0/+9

* Reorganisation of the source treeSimon Marlow2006-04-071-0/+6
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.
