* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* This patch addresses bug 15031.Bill Schmidt2013-01-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 173706
