2013-01-28This patch addresses bug 15031.Bill Schmidt
The common code in the post-RA scheduler to break anti-dependencies on the critical path contained a flaw. In the reported case, an anti-dependency between the overlapping registers %X4 and %R4 exists: %X29<def> = OR8 %X4, %X4 %R4<def>, %X3<def,dead,tied3> = LBZU 1, %X3<kill,tied1> The unpatched code breaks the dependency by replacing %R4 and its uses with %R3, the first register on the available list. However, %R3 and %X3 overlap, so this creates two overlapping definitions on the same instruction. The fix is straightforward, preventing selection of a register that overlaps any other defined register on the same instruction. The test case is reduced from the bug report, and verifies that we no longer produce "lbzu 3, 1(3)" when breaking this anti-dependency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173706 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-28Rewrite the removeAttr() method.Bill Wendling
This now uses the AttributeSet object instead of the Attribute / AttributeWithIndex objects. It's fairly simple now.

2013-01-28Remove a use of AttributeWithIndex.Bill Wendling
We want to remove AttributeWithIndex because it provides a non-encapsulated view of the AttributeSetImpl object. Instead, use accessor methods and iterators.

2013-01-27BBVectorize: Better use of TTI->getShuffleCostHal Finkel
When flipping the pair of subvectors that form a vector, if the vector length is 2, we can use the SK_Reverse shuffle kind to get more-accurate cost information. Also we can use the SK_ExtractSubvector shuffle kind to get accurate subvector extraction costs. The current cost model implementations don't yet seem complex enough for this to make a difference (thus, there are no test cases with this commit), but it should help in future. Depending on how the various targets optimize and combine shuffles in practice, we might be able to get more-accurate costs by combining the costs of multiple shuffle kinds. For example, the cost of flipping the subvector pairs could be modeled as two extractions and two subvector insertions. These changes, however, should probably be motivated by specific test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173621 91177308-0d34-0410-b5e6-96231b3b80d8

for unittests. For example, cur) unittests/ADT/Release/ADTTests new) unittests/ADT/ADTTests RUNTIME_BUILD_MODE can be substituted to CMAKE_CFG_INTDIR. With Make and Ninja, the tree is not built with multiple configurations. Then, including the build type in target directory doesn't make sense. See also "How can I build multiple modes without switching?" http://www.cmake.org/Wiki/CMake_FAQ CMAKE_CFG_INTDIR is set to "." With multiple-configuration-aware build system, like Visual Studio, each unittest is built on appropriate directory, for example, unittests/ADT/Release/ADTTests.exe CMAKE_CFG_INTDIR is set to build system's variable, like "$(Configuration)" or "$(OutDir)". Thus, "--param build_config" is also deprecated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173616 91177308-0d34-0410-b5e6-96231b3b80d8
