| * | improve portability to avoid conflicting with std::next in c++'0x. | Chris Lattner | 2009-12-03 | 1 | -1/+1 |
| | | | | | | | Patch by Howard Hinnant! llvm-svn: 90365 | ||||
| * | Materialize global addresses via movt/movw pair, this is always better | Anton Korobeynikov | 2009-11-24 | 1 | -10/+23 |
| | | | | | | | | | | | | | | 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). llvm-svn: 89720 | ||||
| * | - Add pseudo instructions tLDRpci_pic and t2LDRpci_pic which does a pc-relative | Evan Cheng | 2009-11-06 | 1 | -0/+115 |
| load of a GV from constantpool and then add pc. It allows the code sequence to be rematerializable so it would be hoisted by machine licm. - Add a late pass to break these pseudo instructions into a number of real instructions. Also move the code in Thumb2 IT pass that breaks up t2MOVi32imm to this pass. This is done before post regalloc scheduling to allow the scheduler to proper schedule these instructions. It also allow them to be if-converted and shrunk by later passes. llvm-svn: 86304 | |||||
