* [Refactor][NfC] Simplify and clean the handling of (new) access relationsJohannes Doerfert2014-10-131-1/+1
| | | | | | | | | | | | | | | This patch does not change the semantic on it's own. However, the dependence analysis as well as dce will now use the newest available access relation for each memory access, thus if at some point the json importer or any other pass will run before those two and set a new access relation the behaviour will be different. In general it is unclear if the dependence analysis and dce should be run on the old or new access functions anyway. If we need to access the original access function from the outside later, we can expose the getter again. Differential Revision: http://reviews.llvm.org/D5707 llvm-svn: 219612
* Relax the condition on the jsop accesses regarding the alignment.Johannes Doerfert2014-10-101-12/+30
| | | | | | | | | | | We restricted the new access functions to be a subset of the old one because we want to keep the alignment, however if the alignment is "not special", thus the default for the type, we can allow any access. Differential Revision: http://reviews.llvm.org/D5680 llvm-svn: 219503
* Introduce the ScopArrayInfo class.Johannes Doerfert2014-10-051-0/+3
| | | | | | | | | | | | | | | | | | | This class allows to store information about the arrays in the SCoP. For each base pointer in the SCoP one object is created storing the type and dimension sizes of the array. The objects can be obtained via the SCoP, a MemoryAccess or the isl_id associated with the output dimension of a MemoryAccess (the description of what is accessed). So far we use the information in the IslExprBuilder to create the right base type before indexing into the base array. This fixes the bug http://llvm.org/bugs/show_bug.cgi?id=21113 (both test cases are included). On top of that we can now build runtime alias checks for delinearized arrays as the dimension sizes are also part of the ScopArrayInfo objects.

* Align copied load/store instructions as the original.Johannes Doerfert2014-10-021-0/+15
| | | | | | | | | | This also forbids the json importer to access other memory locations than the original instruction as we to reuse the alignment of the original load/store. Differential Revision: http://reviews.llvm.org/D5560 llvm-svn: 218883

| | | | | | | SVN r209103 removed the OwningPtr variant of the MemoryBuffer APIs. Switch to the equivalent std::unique_ptr versions. This should clear up the build bots. llvm-svn: 209104

* JSONImporter: Free new schedule if found invalidTobias Grosser2013-07-291-0/+4
| | | | | | | | | In case we detect that the schedule the user wants to import is invalid we refuse it _and_ free the isl_maps containing it. Another bug found thanks to Rafael. llvm-svn: 187339

* Move polly options into separate option categoryTobias Grosser2013-05-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Use the new cl::OptionCategory support to move the Polly options into a separate option category. The aim is to hide most options and show by default only the options a user needs to influence '-O3 -polly'. The available options probably need some care, but here is the current status: Polly Options: Configure the polly loop optimizer -enable-polly-openmp - Generate OpenMP parallel code -polly - Enable the polly optimizer (only at -O3) -polly-no-tiling - Disable tiling in the scheduler -polly-only-func=<function-name> - Only run on a single function -polly-report - Print information about the activities of Polly -polly-vectorizer - Select the vectorization strategy =none - No Vectorization =polly - Polly internal vectorizer =unroll-only - Only grouped unroll the vectorize candidate loops =bb - The Basic Block vectorizer driven by Polly llvm-svn: 181295
* Reformat with clang-formatTobias Grosser2013-05-071-9/+11
| | | | | | | clang-format become way more stable. This time we mainly reformat function signatures. llvm-svn: 181294

| | | | llvm-svn: 179160
* clang-format: Many more filesTobias Grosser2013-03-231-49/+48
| | | | | | | | | | | | | After this commit, polly is clang-format clean. This can be tested with 'ninja polly-check-format'. Updates to clang-format may change this, but the differences will hopefully be both small and general improvements to the formatting. We currently have some not very nice formatting for a couple of items, DEBUG() stmts for example. I believe the benefit of being clang-format clean outweights the not perfect layout of this code. llvm-svn: 177796

* ScopInfo: Store ScopStmt pointer in the domainTobias Grosser2012-05-291-0/+12
| | | | | | | | Store a pointer to each ScopStmt in the isl_id associated with the space of its domain. This will later allow us to recover the statement during code generation with isl. llvm-svn: 157607
* Remove FinalReadTobias Grosser2012-03-081-11/+0
| | | | | | | | | | | | | The FinalRead statement represented a virtual read that is executed after the SCoP. It was used when we verified the correctness of a schedule by checking if it yields the same FLOW dependences as the original code. This is only works, if we have a final read that reads all memory at the end of the SCoP. We now switched to just checking if a schedule does not introduce negative dependences and also consider WAW WAR dependences. This restricts the schedules a little bit more, but we do not have any optimizer that would calculate a more complex schedule. Hence, for now final reads are obsolete. llvm-svn: 152319
* Do not use getNameStr() anymore.Tobias Grosser2011-11-171-4/+4
| | | | | | | Instead we switch to the recommended getName(). This fixes compilation with recent versions of LLVM. llvm-svn: 144909
* JSONImporter: Fix parameter ids when importing new access functionsTobias Grosser2011-11-151-0/+19
| | | | | | | | | | The new isl_id support for parmeters created problems when importing new access functions. Even though the parameters had the same names, they were mapped to different ids and where therefore incompatible. We copy the ids now from the old parameter dimensions. This fixes the problem. llvm-svn: 144642
* JScop: Allow to update the contextTobias Grosser2011-11-151-0/+13

| | | | llvm-svn: 144638
* ScopInfo: Only give away a copy of the access relation.Tobias Grosser2011-10-061-7/+10
| | | | | | | | Also take the chance and rename access functions to access relations. This is because we do not only allow plain functions to describe an access, but we can have any access relation that can be described with linear constraints. llvm-svn: 141257
* ScopInfo: Get the isl_ctx always with getIslCtx()Tobias Grosser2011-10-061-2/+2
| | | | llvm-svn: 141254
* Adapt to introduction of isl_spaceTobias Grosser2011-10-061-3/+3
| | | | | | | | Polly should now be compiled with CLooG 0c252c88946b27b7b61a1a8d8fd7f94d2461dbfd and isl 56b7d238929980e62218525b4b3be121af386edf. The most convenient way to update is utils/checkout_cloog.sh. llvm-svn: 141251
* Free isl_ctx and fix several memory leaksTobias Grosser2011-08-201-1/+5
| | | | | | | | | Because of me not understanding the LLVM pass structure well, I did not find a good way to allocate isl_ctx and to free it later without getting issues with reference counting. I now found this place, such that we can free isl_ctx. This patch also fixes the memory leaks that were ignored beforehand. llvm-svn: 138204
* Memaccess: Code generation for constant access function changeRaghesh Aloor2011-08-151-0/+9
| | | | | | | Support for generating code for an access function change which is a constant is added. llvm-svn: 137603
* Memaccess: Display Changed Access RelationRaghesh Aloor2011-08-031-0/+5
| | | | | | | The changed access relations imported from JSCOP file is shown as output of -analyze pass. llvm-svn: 136774
* Memaccess: Bugfix-Reading of JSCoP file failsRaghesh Aloor2011-07-161-1/+1
| | | | | | | While iterating through the memory accesses in JSCOP file the inner loop index was not initialized to zero. llvm-svn: 135340
* MemAccess: Reading Change in Access FunctionRaghesh Aloor2011-07-121-0/+30
| | | | | | | This patch reads the change in access functions from imported JSCOP file. A test case is also added. llvm-svn: 134991
