Tobias Grosser	3d76f2ccd3	[tests] Ensure all test cases use named variables ... This makes it easier to read and possibly even modify the test cases, as there is no need to keep the variable increment in steps of one. More importantly, by using explicit variable names we do not need to rely on the implicit numbering of statements when dumping the scop information. This makes it easier to read and possibly even modify the test cases. Furthermore, by using explicit variables we do not need to rely on the implicit numbering of statements when dumping the scop information. In a future commit, this implicit numbering will likely not be used any more to refer to LLVM-IR values as it is very expensive to construct. llvm-svn: 301689	2017-04-28 21:16:29 +00:00
Tobias Grosser	87dcd46aa7	[tests] Make sure tests do not end in 'unreachable' - Part II ... There is no point in optimizing unreachable code, hence our test cases should always return. This commit is part of a series that makes Polly more robust on the presence of unreachables. llvm-svn: 297150	2017-03-07 15:23:30 +00:00
Eli Friedman	b9c6f01a81	[ScopInfo] Make memset etc. affine where possible. ... We don't actually check whether a MemoryAccess is affine in very many places, but one important one is in checks for aliasing.

Johannes Doerfert	9dd42ee7c1	Try to build alias checks even when non-affine accesses are allowed ... From now on we bail only if a non-trivial alias group contains a non-affine access, not when we discover aliasing and non-affine accesses are allowed. llvm-svn: 261863	2016-02-25 14:06:11 +00:00
