2011-05-31This patch implements atomic intrinsics atomic.load.add (sub,and,or,xor,Bruno Cardoso Lopes
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

2011-05-28Add support for ARM ldrexd/strexd intrinsics. They both use i32 register pairsBruno Cardoso Lopes
to load/store i64 values. Since there's no current support to explicitly declare such restrictions, implement it by using specific hardcoded register pairs during isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132248 91177308-0d34-0410-b5e6-96231b3b80d8

According to PR2536, the old spiller had trouble with the IMPLICIT_DEF in this code: %reg1028<def> = MOV16rm %reg0, 1, %reg0, <ga:g_5>, Mem:LD(2,2) [g_5 + 0] %reg1039<def> = IMPLICIT_DEF %reg1038<def> = INSERT_SUBREG %reg1039, %reg1028, 2 %reg1025<def> = AND32ri %reg1038, 65534, %%EFLAGS<imp-def> However, today we emit a zero-extending load instead: %vreg10<def> = MOVZX32rm16 %noreg, 1, %noreg, <ga:@g_5>, %noreg; %mem:LD2[@g_5] GR32:%vreg10 %vreg0<def> = AND32ri %vreg10, 65534, %%EFLAGS<imp-def,dead>; %GR32:%vreg0,%vreg10 This makes the test pointless since it no longer creates the spiller hazard. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132210 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
