* When using NEON for single-precision FP, the NEON result must be placed in ↵David Goodwin2009-08-053-21/+41
| | | | | | D0-D15 as these are the only D registers with S subregs. Introduce a new regclass to represent D0-D15 and use it in the NEON single-precision FP patterns. llvm-svn: 78244
* Fix some column padding bugs, reorganize things as suggested by ChrisDavid Greene2009-08-051-2/+16

* Fix FindExecutable to use sys::Path::GetMainExecutable instead ofDan Gohman2009-08-051-15/+8
| | | | | | | | | | | | | just argv[0]. And remove the code for searching the current working directory and for searching PATH; the point of FindExecutable is not to find whatever version of the executable can be found by searching around, but to find an executable that accompanies the current executable. Update the tools to use sys::Program::FindProgramByName when they want PATH searching. llvm-svn: 78240

* Restrict LDA to GEPs with the same pointer offset.Andreas Bolka2009-08-051-11/+27
| | | | | | | We can not simply apply ZIV testing to the pointer offsets, as this would incorrectly return independence for e.g. (GEP x,0,i; GEP x,1,-i). llvm-svn: 78155

* Major calling convention code refactoring.Dan Gohman2009-08-0541-2037/+1948
| | | | | | | | | | | | | | | | | | | Instead of awkwardly encoding calling-convention information with ISD::CALL, ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering provides three virtual functions for targets to override: LowerFormalArguments, LowerCall, and LowerRet, which replace the custom lowering done on the special nodes. They provide the same information, but in a more immediately usable format. This also reworks much of the target-independent tail call logic. The decision of whether or not to perform a tail call is now cleanly split between target-independent portions, and the target dependent portion in IsEligibleForTailCallOptimization. This also synchronizes all in-tree targets, to help enable future refactoring and feature work. llvm-svn: 78142

* Don't flush the raw_ostream between each MachineFunction. These flushDan Gohman2009-08-056-12/+0
| | | | | | | | | | | calls were originally put in place because errs() at one time was not unbuffered, and these print routines are commonly used with errs() for debugging. However, errs() is now properly unbuffered, so the flush calls are no longer needed. This significantly reduces the number of write(2) calls for regular asm printing when there are many small functions. llvm-svn: 78137
* Change DAG nodes for Neon VLD2/3/4 operations to return multiple results.Bob Wilson2009-08-054-31/+108
| | | | | | | | | Get rid of yesterday's code to fix the register usage during isel. Select the new DAG nodes to machine instructions. The new pre-alloc pass to choose adjacent registers for these results is not done, so the results of this will generally not assemble yet. llvm-svn: 78136
