* isThumb2 really should mean thumb2 only, not thumb2+.Evan Cheng2009-07-061-1/+1

* Change the meaning of predicate hasThumb2 to mean thumb2 ISA is available, ↵Evan Cheng2009-07-021-1/+2
| | | | | | not that it's in thumb mode and thumb2 is available. Added isThumb2 predicate to replace the old predicate. llvm-svn: 74692
* Revert 74164. We'll want to use this method later.Bob Wilson2009-06-251-0/+1

* Remove unused hasV6T2Ops method. We already have a separate feature toBob Wilson2009-06-251-1/+0

* Latency information for ARM v6. It's rough and not yet hooked up. Right now ↵Evan Cheng2009-06-191-0/+8
| | | | | | we are only using branch latency to determine if-conversion limits. llvm-svn: 73747

Instead of using intermediate nodes, expand the operations, choosing between simple loads/stores, target-specific code, and library calls, immediately. Previously, the code to emit optimized code for these operations was only used at initial SelectionDAG construction time; now it is used at all times. This fixes some cases where rep;movs was being used for small copies where simple loads/stores would be better. This also cleans up code that checks for alignments less than 4; let the targets make that decision instead of doing it in target-independent code. This allows x86 to use rep;movs in low-alignment cases. Also, this fixes a bug that resulted in the use of rep;stos for memsets of 0 with non-constant memory size when the alignment was at least 4. It's better to use the library in this case, which can be significantly faster when the size is large. This also preserves more SourceValue information when memory intrinsics are lowered into simple loads/stores. llvm-svn: 49572

* Make ARM and X86 LowerMEMCPY identical by moving the isThumb check into ↵Rafael Espindola2007-10-311-1/+5
| | | | | | | | | | getMaxInlineSizeThreshold and by restructuring the X86 version. New I just have to move this to a common place :-) llvm-svn: 43554
* Make ARM an X86 memcpy expansion more similar to each other.Rafael Espindola2007-10-311-0/+1
| | | | | | | | Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it. This should not change generated code. llvm-svn: 43552
