2010-06-25The hasMemory argument is irrelevant to how the argumentDale Johannesen
for an "i" constraint should get lowered; PR 6309. While this argument was passed around a lot, this is the only place it was used, so it goes away from a lot of other places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106893 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-21Mark the SPU 'lr' instruction to never have side effects. Kalle Raiskila
This allows the fast regiser allocator to remove redundant register moves. Update a set of tests that depend on the register allocator to be linear scan. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106420 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-17Add a DebugLoc parameter to TargetInstrInfo::InsertBranch(). ThisStuart Hastings
addresses a longstanding deficiency noted in many FIXMEs scattered across all the targets. This effectively moves the problem up one level, replacing eleven FIXMEs in the targets with eight FIXMEs in CodeGen, plus one path through FastISel where we actually supply a DebugLoc, fixing Radar 7421831. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106243 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-14Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe whatBill Wendling
the variable actually tracks. N.B., several back-ends are using "HasCalls" as being synonymous for something that adjusts the stack. This isn't 100% correct and should be looked into. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103802 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Use cast instead of dyn_cast when assuming success.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101636 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-09"On SPU, variables in the .bss section that are allocated with the .lcomm ↵Chris Lattner
directive are not aligned on 16 byte boundaries.

2010-04-04Momentous day: remove the "O" member from AsmPrinter. Now all Chris Lattner
"asm printering" happens through MCStreamer. This also Streamerizes PIC16 debug info, which escaped my attention. This removes a leak from LLVMTargetMachine of the 'legacy' output stream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100327 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29From Kalle Raiskila:Chris Lattner
"the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions: -in vararg handling, registers are marked to be live, to not confuse the register scavenger -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the register scavenger emergency spill slot, which is not used as there is no stack." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99819 91177308-0d34-0410-b5e6-96231b3b80d8
