| | | | llvm-svn: 59566
* We also need to keep the operand index for two address check.Evan Cheng2008-11-181-9/+11
| | | | llvm-svn: 59562
* Register scavenger should process early clobber defs first. A dead early ↵Evan Cheng2008-11-181-23/+37
| | | | | | clobber def should not interfere with a normal def which happens one slot later. llvm-svn: 59559
* Tidy up ScheduleNodeBottomUp methods, and make them moreDan Gohman2008-11-182-10/+8
| | | | | | consistent with ScheduleNodeTopDown methods. llvm-svn: 59550
* Update a comment to reflect the current code.Dan Gohman2008-11-181-3/+2
| | | | llvm-svn: 59549
* Remove integer promotion support for FP_EXTENDDuncan Sands2008-11-182-16/+1
| | | | | | | | | and FP_ROUND. Not sure what these were doing here - probably they were sometimes (wrongly) created with integer operands somewhere that has since been fixed. llvm-svn: 59548
* Simplify code using helper routines. There is notDuncan Sands2008-11-182-67/+53
| | | | | | supposed to be any functionality change. llvm-svn: 59545
* Fix a bug introduced by my previous patch. With this change, SPEC is now ↵Owen Anderson2008-11-181-1/+1
| | | | | | clean with prealloc splitting enabled. llvm-svn: 59544

| | | | llvm-svn: 59532
* LegalizeTypes support for splitting and scalarizingDuncan Sands2008-11-182-11/+27
| | | | | | | | SCALAR_TO_VECTOR. I didn't add the testcase, because once llc gets past scalar-to-vector it hits a SPU target lowering bug and explodes. llvm-svn: 59530
* Rename stackprotector_create intrinsic to stackprotector.Bill Wendling2008-11-182-2/+2
| | | | llvm-svn: 59519
* Reapply r59464, this time using the correct typeDuncan Sands2008-11-182-4/+188
| | | | | | when softening FNEG. llvm-svn: 59513

| | | | llvm-svn: 59504

| | | | | | | | | - Use less indentation in coding. - Shorten description. - Update comments. - Move code around llvm-svn: 59496
* Fix a typo in a comment.Dan Gohman2008-11-181-1/+1
| | | | llvm-svn: 59489

* Avoid using a loop in ReleasePred and ReleaseSucc methods to compute theDan Gohman2008-11-183-55/+64
| | | | | | | | | | | | | new CycleBound value. Instead, just update CycleBound on each call. Also, make ReleasePred and ReleaseSucc methods more consistent accross the various schedulers. This also happens to make ScheduleDAGRRList's CycleBound computation somewhat more interesting, though it still doesn't have any noticeable effect, because no current targets that use the register-pressure reduction scheduler provide pipeline models. llvm-svn: 59475
* Eliminate some trivial differences between the ScheduleNodeTopDownDan Gohman2008-11-172-6/+8

* Improved shuffle normalization to avoid using extract/build when weMon P Wang2008-11-161-96/+122

* Remove the FlaggedNodes member from SUnit. Instead of requiring each SUnitDan Gohman2008-11-136-59/+49
| | | | | | | | | | to carry a SmallVector of flagged nodes, just calculate the flagged nodes dynamically when they are needed. The local-liveness change is due to a trivial scheduling change where the scheduler arbitrary decision differently. llvm-svn: 59273
* Don't allow the restore point to be placed after terminators. With this change,Owen Anderson2008-11-131-2/+2
