2009-08-11Rebuild RegScavenger::DistanceMap each time it is needed.Jakob Stoklund Olesen
The register scavenger maintains a DistanceMap that maps MI pointers to their distance from the top of the current MBB. The DistanceMap is built incrementally in forward() and in bulk in findFirstUse(). It is used by scavengeRegister() to determine which candidate register has the longest unused interval. Unfortunately the DistanceMap contents can become outdated. The first time scavengeRegister() is called, the DistanceMap is filled to cover the MBB. If then instructions are inserted in the MBB (as they always are following scavengeRegister()), the recorded distances are too short. This causes bad behaviour in the included test case where a register use /after/ the current position is ignored because findFirstUse() thinks is is /before/ the current position. A "using an undefined register" assertion follows promptly. The fix is to build a fresh DistanceMap at the top of scavengeRegister(), and discard it after use. This means that DistanceMap is no longer needed as a RegScavenger member variable, and forward() doesn't need to update it. The fix then discloses issue number two in the same test case: The candidate search in scavengeRegister() finds a CSR that has been saved in the prologue, but is currently unused. It would be both inefficient and wrong to spill such a register in the emergency spill slot. In the present case, the emergency slot restore is placed immediately before the normal epilogue restore, leading to a "Redefining a live register" assertion. Fix number two: When scavengerRegister() stumbles upon an unused register that is overwritten later in the MBB, return that register early. It is important to verify that the register is defined later in the MBB, otherwise it might be an unspilled CSR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78650 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-11Use vAny type to get rid of Neon intrinsics that differed only in whetherBob Wilson
the overloaded vector types allowed floating-point or integer vector elements. Most of these operations actually depend on the element type, so bitcasting was not an option. If you include the vpadd intrinsics that I updated earlier, this gets rid of 20 intrinsics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78646 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-10Fix a bug in the DAGCombiner's handling of multiple linkedDan Gohman
MERGE_VALUES nodes. Replacing the result values with the operands in one MERGE_VALUES node may cause another MERGE_VALUES node be CSE'd with the first one, and bring its uses along, so that the first one isn't dead, as this code expects. Fix this by iterating until the node is really dead. This fixes PR4699. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78619 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-10Make the big switch: Change MCSectionMachO to represent a section *semantically*Chris Lattner
instead of syntactically as a string. This means that it keeps track of the segment, section, flags, etc directly and asmprints them in the right format. This also includes parsing and validation support for llvm-mc and "attribute(section)", so we should now start getting errors about invalid section attributes from the compiler instead of the assembler on darwin. Still todo: 1) Uniquing of darwin mcsections 2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h] 3) there are a few FIXMEs, for example what is the syntax to get the S_GB_ZEROFILL segment type? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78547 91177308-0d34-0410-b5e6-96231b3b80d8

Verify that early clobber registers and their aliases are not used. All changes to RegsAvailable are now done as a transaction so the order of operands makes no difference.

2009-08-08llvm-mc/AsmMatcher: Improve match code.Daniel Dunbar
- This doesn't actually improve the algorithm (its still linear), but the generated (match) code is now fairly compact and table driven. Still need a generic string matcher. - The table still needs to be compressed, this is quite simple to do and should shrink it to under 16k. - This also simplifies and restructures the code to make the match classes more explicit, in anticipation of resolving ambiguities. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78461 91177308-0d34-0410-b5e6-96231b3b80d8
