* Enable predication of NEON instructions in Thumb2 mode.Evan Cheng2009-11-24
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89748 91177308-0d34-0410-b5e6-96231b3b80d8
* Materialize global addresses via movt/movw pair, this is always betterAnton Korobeynikov2009-11-24
| | | | | | | | | | | | | than doing the same via constpool: 1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2. 2. Load from constpool might stall up to 300 cycles due to cache miss. 3. Movt/movw does not use load/store unit. 4. Less constpool entries => better compiler performance. This is only enabled on ELF systems, since darwin does not have needed relocations (yet). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89720 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix pr5470. Tablegen handles template arguments by temporarily setting theirBob Wilson2009-11-22
| | | | | | | | | | | | values, resolving references to them, and then removing the definitions. If a template argument is set to an undefined value, we need to resolve references to that argument to an explicit undefined value. The current code leaves the reference to the template argument as it is, which causes an assertion failure later when the definition of the template argument is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89581 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | which was an expensive checks failure due to a bug in the checking. This patch in essence reverts the original fix for PR3393, and refixes it by a tweak to the way expensive checking is done. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89454 91177308-0d34-0410-b5e6-96231b3b80d8
