2010-07-02Clean up TargetOpcodes.h a bit, and limit the number of places where the fullJakob Stoklund Olesen
list of predefined instructions appear. Add some consistency checks. Ideally, TargetOpcodes.h should be produced by TableGen from Target.td, but it is hardly worth the effort. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107520 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Add a pseudo instruction REG_SEQUENCE that takes a list of registers andEvan Cheng
sub-register indices and outputs a single super register which is formed from a consecutive sequence of registers. This is used as register allocation / coalescing aid and it is useful to represent instructions that output register pairs / quads. For example, v1024, v1025 = vload <address> where v1024 and v1025 forms a register pair. This really should be modelled as v1024<3>, v1025<4> = vload <address> but it would violate SSA property before register allocation is done. Currently we use insert_subreg to form the super register: v1026 = implicit_def v1027 - insert_subreg v1026, v1024, 3 v1028 = insert_subreg v1027, v1025, 4 ... = use v1024 = use v1028 But this adds pseudo live interval overlap between v1024 and v1025. We can now modeled it as v1024, v1025 = vload <address> v1026 = REG_SEQUENCE v1024, 3, v1025, 4 ... = use v1024 = use v1026 After coalescing, it will be v1026<3>, v1025<4> = vload <address> ... = use v1026<3> = use v1026 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102815 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-28Introduce the TargetInstrInfo::KILL machine instruction and get rid of theJakob Stoklund Olesen
unused DECLARE instruction. KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF in the places where IMPLICIT_DEF is just used to alter liveness of physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83006 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13Add a new TargetInstrInfo MachineInstr opcode, COPY_TO_SUBCLASS.Dan Gohman
This will be used to replace things like X86's MOV32to32_. Enhance ScheduleDAGSDNodesEmit to be more flexible and robust in the presense of subregister superclasses and subclasses. It can now cope with the definition of a virtual register being in a subclass of a use. Re-introduce the code for recording register superreg classes and subreg classes. This is needed because when subreg extracts and inserts get coalesced away, the virtual registers are left in the correct subclass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68961 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-01Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman
the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-16Make insert_subreg a two-address instruction, vastly simplifying ↵Christopher Lamb
LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48412 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-02SDIsel processes llvm.dbg.declare by recording the variable debug ↵Evan Cheng
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
