MipsFrameLowering::emitPrologue: - cfi directives are not inserted at the right location or in the right order. - The source MachineLocation for the cfi directive that changes the cfa register to $fp should be MachineLocation::VirtualFP. - A PROLOG_LABEL that marks the beginning of cfi_offset directives for callee-saved register is emitted even when no callee-saved registers are saved. - When a callee-saved double precision register is saved, two cfi_offset directives, one for each of the paired single precision registers, should be emitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132703 91177308-0d34-0410-b5e6-96231b3b80d8

nand), atomic.swap and atomic.cmp.swap, all in i8, i16 and i32 versions. The intrinsics are implemented by creating pseudo-instructions, which are then expanded in the method MipsTargetLowering::EmitInstrWithCustomInserter.

2011-05-29Fix PR10046 by updating LiveVariables kill info when splitting live ranges.Jakob Stoklund Olesen
This only affects targets like Mips where branch instructions may kill virtual registers. Most other targets branch on flag values, so virtual registers are not involved. The problem is that MachineBasicBlock::updateTerminator deletes branches and inserts new ones while LiveVariables keeps a list of pointers to instructions that kill virtual registers. That list wasn't properly updated in MBB::SplitCriticalEdge. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132298 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-23Change StackDirection from StackGrowsUp to StackGrowsDown.Akira Hatanaka
The following improvements are accomplished as a result of applying this patch: - Fixed frame objects' offsets (relative to either the virtual frame pointer or the stack pointer) are set before instruction selection is completed. There is no need to wait until Prologue/Epilogue Insertion is run to set them. - Calculation of final offsets of fixed frame objects is straightforward. It is no longer necessary to assign negative offsets to fixed objects for incoming arguments in order to distinguish them from the others. - Since a fixed object has its relative offset set during instruction selection, there is no need to conservatively set its alignment to 4. - It is no longer necessary to reorder non-fixed frame objects in MipsFrameLowering::adjustMipsStackFrame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131915 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-13Recommit r129383. PreRA scheduler heuristic fixes: VRegCycle, TokenFactor ↵Andrew Trick
latency. Additional fixes: Do something reasonable for subtargets with generic itineraries by handle node latency the same as for an empty itinerary. Now nodes default to unit latency unless an itinerary explicitly specifies a zero cycle stage or it is a TokenFactor chain. Original fixes: UnitsSharePred was a source of randomness in the scheduler: node priority depended on the queue data structure. I rewrote the recent VRegCycle heuristics to completely replace the old heuristic without any randomness. To make the ndoe latency adjustments work, I also needed to do something a little more reasonable with TokenFactor. I gave it zero latency to its consumers and always schedule it as low as possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129421 91177308-0d34-0410-b5e6-96231b3b80d8
