* This is the initial check-in for adding register scavenging to PPC. (Currently,Bill Wendling2008-03-035-104/+365
| | | | | | | | | | | PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that it uses a register other than the default R0 register (the scavenger scrounges for one). A significant part of this patch fixes how kill information is handled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47863 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | %r3 on PPC) in their ASM files. However, it's hard for humans to read during debugging. Adding a new field to the register data that lets you specify a different name to be printed than the one that goes into the ASM file -- %x3 instead of %r3, for instance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47534 91177308-0d34-0410-b5e6-96231b3b80d8

* Change how FP immediates are handled. Nate Begeman2008-02-141-3/+0
| | | | | | | | | | | | | | | 1) ConstantFP is now expand by default 2) ConstantFP is not turned into TargetConstantFP during Legalize if it is legal. This allows ConstantFP to be handled like Constant, allowing for targets that can encode FP immediates as MachineOperands. As a bonus, fix up Itanium FP constants, which now correctly match, and match more constants! Hooray. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47121 91177308-0d34-0410-b5e6-96231b3b80d8

* Dwarf requires variable entries to be in the source order. Right now, since ↵Evan Cheng2008-02-041-1/+0

* SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng2008-02-021-0/+1
| | | | | | | | | | information descriptor and its corresponding stack frame index in MachineModuleInfo. This only works if the local variable is "homed" in the stack frame. It does not work for byval parameter, etc. Added ISD::DECLARE node type to represent llvm.dbg.declare intrinsic. Now the intrinsic calls are lowered into a SDNode and lives on through out the codegen passes. For now, since all the debugging information recording is done at isel time, when a ISD::DECLARE node is selected, it has the side effect of also recording the variable. This is a short term solution that should be fixed in time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46659 91177308-0d34-0410-b5e6-96231b3b80d8
