* [tests] Force invariant load hoisting for test cases that need it -- IIITobias Grosser2016-08-151-1/+2
| | | | llvm-svn: 278673
* tests: Drop -polly-detect-unprofitable and -polly-no-early-exitTobias Grosser2015-10-061-1/+1
| | | | | | | | These flags are now always passed to all tests and need to be disabled if not needed. Disabling these flags, rather than passing them to almost all tests, significantly simplfies our RUN: lines. llvm-svn: 249422
* Identify and hoist definitively invariant loadsJohannes Doerfert2015-09-291-2/+5
| | | | | | | | | | | | | | | | | | | As a first step in the direction of assumed invariant loads (loads that are not written in some context) we now detect and hoist definitively invariant loads. These invariant loads will be preloaded in the code generation and used in the optimized version of the SCoP. If the load is only conditionally executed the preloaded version will also only be executed under the same condition, hence we will never access memory that wouldn't have been accessed otherwise. This is also the most distinguishing feature to licm. As hoisting can make statements empty we will simplify the SCoP and remove empty statements that would otherwise cause artifacts in the code generation.

* Rename IslCodeGeneration to CodeGenerationTobias Grosser2015-05-121-1/+1
| | | | | | | | | Besides class, function and file names, we also change the command line option from -polly-codegen-isl to just -polly-codegen. The isl postfix is a leftover from the times when we still had the CLooG based -polly-codegen. Today it is just redundant and we drop it. llvm-svn: 237099
* Remove target triples from test casesTobias Grosser2015-04-211-1/+0
| | | | | | | | I just learned that target triples prevent test cases to be run on other architectures. Polly test cases are until now sufficiently target independent to not require any target triples. Hence, we drop them. llvm-svn: 235384
* [tests] Use -polly-vectorizer=polly directlyTobias Grosser2015-04-051-1/+1
| | | | | | instead of defining a lit variable %vector-opt. llvm-svn: 234112

* ScopDetection: Only detect scops that have at least one read and one writeTobias Grosser2015-02-191-1/+1
| | | | | | | | | | Scops that only read seem generally uninteresting and scops that only write are most likely initializations where there is also little to optimize. To not waste compile time we bail early. Differential Revision: http://reviews.llvm.org/D7735 llvm-svn: 229820
* Replace %defaultOpts with explicit pass namesTobias Grosser2014-08-301-1/+1
| | | | | | | | | | | | | | | | | | | | This replaces the use of %defaultOpts = '-basicaa -polly-prepare' with the minimal set of passes necessary for a test to succeed. Of the test cases that previously used %defaultOpts 76 test cases require none of these passes, 42 need -basicaa and only 2 need -polly-prepare. Our change makes this requirement explicit. In Polly many test cases have been using a macro '%defaultOpts' which run a couple of preparing passes before the actual Polly test case. This macro was introduced very early in the development of Polly and originally contained a large set of canonicalization passes. However, as the need for additional canonicalization passes makes test cases harder to understand and also more fragile in terms of changes in such passes, we aim since a longer time to only include the minimal set of passes necessary. This patch removes the last leftovers from of %defaultOpts and brings our tests cases more in line to what is usus in LLVM itself. llvm-svn: 216815
