* Significant changes to correctly spill CC registers and to correctlyVikram S. Adve2002-07-08
| | | | | | | | | | | | | | | | | | handle conditional move instructions: -- cpMem<->Reg functions now support CC registers (int and FP) correctly. -- Scratch registers must be explicitly provided to cpMem<->Reg when needed, since CC regs need one to be copied to/from memory. -- CC regs are saved to a scratch register instead of stack. -- All regs used by a instruction are now recorded in MachineInstr::regsUsed, since regs used to save values *across* an instruction are not obvious either from the operands or from the LiveVar sets. -- An (explicit or implicit) operand may now be both a def and a use. This is needed for conditional move operations. So an operand may need spill code both before and after the instruction. -- class MachineCodeForBasicBlock is now an annotation on BasicBlock. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2833 91177308-0d34-0410-b5e6-96231b3b80d8
* MachineInstr* in vector are not const (and never really were)Vikram S. Adve2002-07-08
| | | | | | | | because operands may be modified directly to set register. Also, class MachineCodeForBasicBlock is now an annotation on BasicBlock. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2832 91177308-0d34-0410-b5e6-96231b3b80d8

* Implementation of class MachineCodeForBasicBlock.Vikram S. Adve2002-07-08
| | | | | | | Moved here from MachineInstr.cpp to make it an annotation on BasicBlock. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2827 91177308-0d34-0410-b5e6-96231b3b80d8
* A single MachineInstr operand may now be both a def and a use,Vikram S. Adve2002-07-08
| | | | | | | | | | so additional dep. edges have to be added. This was needed to correctly handle conditional move instructions! MachineCodeForBasicBlock is now an annotation on BasicBlock. Renamed "earliestForNode" to "earliestReadyTimeForNode". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2826 91177308-0d34-0410-b5e6-96231b3b80d8

* Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}.Vikram S. Adve2002-07-08
| | | | | | | | | An (explicit or implicit) operand may now be both a def and a use. Also add a set of regs used by each instruction. dump() no longer takes an optional argument, which doesn't work in gdb. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2821 91177308-0d34-0410-b5e6-96231b3b80d8

* Numerous bug fixes:Vikram S. Adve2002-05-19
| | | | | | | | | | | | | | | | | | | | -- passing FP arguments to functions with more than 6 arguments -- passing FP arguments to varargs functions -- passing FP arguments to functions with no prototypes -- incorrect coloring for CC registers (both int and FP): interferences were being completely ignored for int CC and were considered but no spills were marked for fp CC! Also some code improvements: -- better interface to generating machine instr for common cases (many places still need to be updated to use this interface) -- annotations on MachineInstr to communicate information from one codegen phase to another (now used to pass information about CALL/JMPLCALL operands from selection to register allocation) -- all sizes and offests in class TargetData are uint64_t instead of uint git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2642 91177308-0d34-0410-b5e6-96231b3b80d8
