* CMake: Removed source file.Oscar Fuentes2008-11-191-1/+0
| | | | llvm-svn: 59662
* Do not use separate utility to walk all instructions and remove dead dbg ↵Devang Patel2008-11-191-60/+0
| | | | | | intrinsics. Let instcombiner do this job. llvm-svn: 59659
* Let instcombiner remove redundant dbg intrinsics.Devang Patel2008-11-191-7/+1
| | | | llvm-svn: 59658
* If there are two consecutive llvm.dbg.stoppoint calls thenDevang Patel2008-11-191-1/+16
| | | | | | | it is likely that the optimizer deleted code in between these two intrinsics. Keep only the last llvm.dbg.stoppoint in this case. llvm-svn: 59657

| | | | | | | Discourage (allocate last) use of x86_64 R12 and R13 due to their longer instruction encodings. llvm-svn: 59644

| | | | | | ExpandIntegerOperand (LegalizeIntegerTypes.cpp) is needed which is yet to be reworked and submitted. llvm-svn: 59617

| | | | | | intrinsic. llvm-svn: 59614
* Add support for rematerialization in pre-alloc-splitting.Owen Anderson2008-11-191-3/+95
| | | | llvm-svn: 59587
* Rearrange code to reduce the nesting level. No functionality change.Dan Gohman2008-11-191-36/+36
| | | | llvm-svn: 59580

| | | | llvm-svn: 59569
* Fix debug printing of flagged SDNodes in SUnits so that theyDan Gohman2008-11-191-12/+12
| | | | | | print in the correct order. llvm-svn: 59567
* Make the same change to RegScavenger::backward.Evan Cheng2008-11-181-9/+28

* Verify that the second parameter of the stacprotector intrinsic is an allocaBill Wendling2008-11-181-0/+5
| | | | | | instruction. llvm-svn: 59563
* 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
* Add new helper pass that strips all symbol names except debugging information.Devang Patel2008-11-181-28/+51
| | | | | | This pass makes it easier to test wheter debugging info. influences optimization passes or not. llvm-svn: 59552
* Don't set neverHasSideEffects on x86's divide instructions, sinceDan Gohman2008-11-182-3/+1
| | | | | | | they trap on divide-by-zero, and this side effect is otherwise unmodeled. llvm-svn: 59551
* 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
* Remove even more llvm.dbg variables.Devang Patel2008-11-181-33/+50
| | | | | | | Remove all dead globals from llvm.metadata. Ignore linkonce linkage for selected llvm.dbg values. llvm-svn: 59547
* 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
* Add more const qualifiers. This fixes build breakage from r59540.Dan Gohman2008-11-1819-41/+64
| | | | llvm-svn: 59542
* Make some methods const.Dan Gohman2008-11-181-2/+4
| | | | llvm-svn: 59540
* Initialize MallocFunc and FreeFunc properly.Devang Patel2008-11-181-1/+1
| | | | llvm-svn: 59538
* Whitespace cleanups.Dan Gohman2008-11-181-2/+2
| | | | 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
* Add a utility function that detects whether a loop is guaranteed to be finite.Nick Lewycky2008-11-181-31/+127
| | | | | | | | | | | Use it to safely handle less-than-or-equals-to exit conditions in loops. These also occur when the loop exit branch is exit on true because SCEV inverses the icmp predicate. Use it again to handle non-zero strides, but only with an unsigned comparison in the exit condition. llvm-svn: 59528
* Rename stackprotector_create intrinsic to stackprotector.Bill Wendling2008-11-182-2/+2
| | | | llvm-svn: 59519
* Cast to remove warning about comparing signed and unsigned.Bill Wendling2008-11-181-1/+1
| | | | llvm-svn: 59518
* Implement support for JIT exceptions on X86_64. Relative offsets areNicolas Geoffray2008-11-181-61/+27
| | | | | | | encoded on 32 bytes, and the personality function is not encoded as relative. llvm-svn: 59516
* Remove unused variable.Duncan Sands2008-11-181-3/+0
| | | | llvm-svn: 59515
* Reapply r59464, this time using the correct typeDuncan Sands2008-11-182-4/+188
| | | | | | when softening FNEG. llvm-svn: 59513
* Remove the stackprotector_check intrinsic. Use a volatile load instead.Bill Wendling2008-11-182-19/+4
| | | | llvm-svn: 59504
* - Use "moveAfter" instead of "remove/insert" of a basic block.Bill Wendling2008-11-181-103/+104
| | | | | | | | | - 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
* Change SUnit's dump method to take a ScheduleDAG* instead ofDan Gohman2008-11-184-23/+23
| | | | | | a SelectionDAG*. llvm-svn: 59488
