Vikram S. Adve 689adb19b0 Change interface to MachineInstr::substituteValue to specify more precisely 
which args can be substituted: defsOnly, defsAndUses or usesOnly.

llvm-svn: 7154
 2003-07-10 19:45:07 +00:00
Vikram S. Adve c468882155 Allow explicit physical registers for implicit operands. 
llvm-svn: 6468
 2003-05-31 07:39:06 +00:00
Vikram S. Adve 7366fa1aa6 (1) Added special register class containing (for now) %fsr. 
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".

 2002-10-28 20:59:49 +00:00
Chris Lattner ca4a9d20b8 * Make MachineOperand ctors private, so MachineOperand can only be created 
by MachineInstr.
* Add a bunch of new methods to allow incremental addition of operands to the
  machine instr instance.

llvm-svn: 4356
 2002-10-28 20:48:39 +00:00

Chris Lattner 340bb96e64 Fairly major overhaul of MachineInstr & Operand classes

llvm-svn: 4327
 2002-10-28 02:28:39 +00:00
Chris Lattner ce64eddb71 - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

llvm-svn: 4261
 2002-10-22 23:16:21 +00:00

per operand.

llvm-svn: 2860
 2002-07-10 21:45:04 +00:00
Vikram S. Adve 6c013a9689 Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}. 
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.

Vikram S. Adve 6d19dc9080 1. Add a bottom-up pass on BURG trees that is used to fix constant operands. 
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.
