* Simplify .gitignore filesHerbert Valerio Riedel2014-06-281-11/+0
| | | | | | | | | It's a bit confusing to have .gitignore files spread all over the filesystem. This commit tries to consolidate those into one .gitignore file per component. Moreover, we try to describe files to be ignored which happen to have a common identifying pattern by glob patterns. Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
* Fix discarding of unreachable code in the register allocator (#9155)Simon Marlow2014-06-062-0/+31
| | | | | | | A previous fix to this was wrong: f5879acd018494b84233f26fba828ce376d0f81d and left some unreachable code behind. So rather than try to be clever and do this at the same time as the strongly-connected-component analysis, I'm doing a separate reachability pass first.
* Add .gitignore for autogenerated test files.Edward Z. Yang2014-05-291-0/+11
| | | | | | | | I used this shell command to automatically generate the lists: for i in `git ls-files -o --exclude-standard --directory`; do echo "`basename $i`" >> "`dirname "$i"`/.gitignore"; done Signed-off-by: Edward Z. Yang <ezyang@cs.stanford.edu>

* Add SmallArray# and SmallMutableArray# typesJohan Tibell2014-03-297-0/+752
| | | | | | | | | | | | | | | These array types are smaller than Array# and MutableArray# and are faster when the array size is small, as they don't have the overhead of a card table. Having no card table reduces the closure size with 2 words in the typical small array case and leads to less work when updating or GC:ing the array. Reduces both the runtime and memory allocation by 8.8% on my insert benchmark for the HashMap type in the unordered-containers package, which makes use of lots of small arrays. With tuned GC settings (i.e. `+RTS -A6M`) the runtime reduction is 15%. Fixes #8923.
* Add flags to control memcpy and memset inliningJohan Tibell2014-03-263-0/+24
| | | | | | | This adds -fmax-inline-memcpy-insns and -fmax-inline-memset-insns. These flags control when we inline calls to memcpy/memset with statically known arguments. The flag naming style is taken from GCC and the same limit is used by both GCC and LLVM.
* Enable popcnt test now when segfault is fixedJohan Tibell2014-03-221-1/+1

* codeGen: inline allocation optimization for clone array primopsJohan Tibell2014-03-222-4/+83
| | | | | | | | | | | | | | | | | | | | | | | | The inline allocation version is 69% faster than the out-of-line version, when cloning an array of 16 unit elements on a 64-bit machine. Comparing the new and the old primop implementations isn't straightforward. The old version had a missing heap check that I discovered during the development of the new version. Comparing the old and the new version would requiring fixing the old version, which in turn means reimplementing the equivalent of MAYBE_CG in StgCmmPrim. The inline allocation threshold is configurable via -fmax-inline-alloc-size which gives the maximum array size, in bytes, to allocate inline. The size does not include the closure header size. Allowing the same primop to be either inline or out-of-line has some implication for how we lay out heap checks. We always place a heap check around out-of-line primops, as they may allocate outside of our knowledge. However, for the inline primops we only allow allocation via the standard means (i.e. virtHp). Since the clone primops might be either inline or out-of-line the heap check layout code now consults shouldInlinePrimOp to know whether a primop will be inlined.
* codeGen: allocate small byte arrays of statically known size inlineJohan Tibell2014-03-143-0/+54
| | | | | | | This results in a 57% runtime decrease when allocating an array of 128 bytes on a 64-bit machine. Fixes #8876.

| | | | | | | | | | | | | | | | This includes: * Adding a test for bswap16 with a low byte >= 128 * Also test the byteSwapN functions from GHC.Word, tested both INLINE and not INLINE, so we test both independent parts: the compilation of base, and the backend compiling the code *using* base. * Fix the usage of byteSwapN# primitives in the test, by masking off * the higher bits when storing the results in Word16/Word32.
