* Use const qualifiers with TargetLowering. This eliminates severalDan Gohman2010-04-171-2/+2
| | | | | | | | | | | | | | const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen2010-03-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | crossings. On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register in a different domain than where it was defined. Some instructions have equvivalents for different domains, like por/orps/orpd. The SSEDomainFix pass tries to minimize the number of domain crossings by changing between equvivalent opcodes where possible. This is a work in progress, in particular the pass doesn't do anything yet. SSE instructions are tagged with their execution domain in TableGen using the last two bits of TSFlags. Note that not all instructions are tagged correctly. Life just isn't that simple. The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline issue handled by NEONMoveFixPass. This pass may become target independent to handle both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99524 91177308-0d34-0410-b5e6-96231b3b80d8
