2003-07-02A def. operand of a machine instruction may be an ordinary Value*,Vikram S. Adve
not just an Instruction*, at least in one unfortunate case: the first operand to the va_arg instruction. Modify ValueToDefVecMap to map from Value*, not Instruction*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7052 91177308-0d34-0410-b5e6-96231b3b80d8
2003-05-31Changes to allow explicit physical register arguments that have beenVikram S. Adve
preallocated. While reg-to-reg dependences were already handled, this change required new code for adding edges to/from call instructions. This was part of the extensive changes to the way code generation occurs for function call arguments and return values. See log for CodeGen/PhyRegAlloc.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6467 91177308-0d34-0410-b5e6-96231b3b80d8
2003-05-27(1) Added special register class containing (for now) %fsr.Vikram S. Adve
Fixed spilling of %fcc[0-3] which are part of %fsr. (2) Moved some machine-independent reg-class code to class TargetRegInfo from SparcReg{Class,}Info. (3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() and related functions and flags. Fixed several bugs where only "isDef" was being checked, not "isDefAndUse". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6341 91177308-0d34-0410-b5e6-96231b3b80d8

2002-07-08A single MachineInstr operand may now be both a def and a use,Vikram S. Adve
so additional dep. edges have to be added. This was needed to correctly handle conditional move instructions! MachineCodeForBasicBlock is now an annotation on BasicBlock.

2002-04-09Clean up the ownership model a bit so that nodes actually get deleted moreChris Lattner
frequently. This still leaks edges quite a bit, but it leaks no nodes (I think). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2190 91177308-0d34-0410-b5e6-96231b3b80d8

2001-11-12Eliminate most uses of the machine instruction vector for each LLVM instr,Vikram S. Adve
since some m. instr. may be generated by LLVM instrs. in other blocks. Handle non-SSA (anti and output) edges and true edges uniformly by working with machine instructions alone. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1269 91177308-0d34-0410-b5e6-96231b3b80d8

LLVM instruction is no longer recorded in each node, but BB is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1262 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-11Only add true dep. edges from an earlier to a later instruction.Vikram S. Adve
This wasn't a problem until we started putting copies for Phi values that produced cycles in the SchedGraph! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1254 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-08Major change to how defs are found when adding dependences (theyVikram S. Adve
are now found as part of the initial walk of the machine code). Also memory load/store instructions can be generated for non-memory LLVM instructions, which wasn't handled before. It is now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1199 91177308-0d34-0410-b5e6-96231b3b80d8
2001-11-05Modified graph construction to use one pass to find all defs.Vikram S. Adve
Avoids having to handle some special cases that cause complex interactions with instr. selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1138 91177308-0d34-0410-b5e6-96231b3b80d8

(b) any instructions that use or set CC registers. Whether or not the latter are needed really should be machine-dependent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1008 91177308-0d34-0410-b5e6-96231b3b80d8
