Vikram S. Adve abf331db03 isMarkedForSpill() should be const. 
llvm-svn: 7155
 2003-07-10 19:45:28 +00:00
Vikram S. Adve 39587d6264 Print out all neighbors in interference graph, not just higher-numbered ones. 
llvm-svn: 7153
 2003-07-10 19:43:33 +00:00
Vikram S. Adve 5224b19deb Several fixes to handling of int CC register: 
(1) An int CC live range must be spilled if there are any interferences,
    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same
register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
    phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
    deal with this.

Vikram S. Adve 24ce4d8eb8 Minor changes. 
llvm-svn: 6470
 2003-05-31 07:41:54 +00:00
Vikram S. Adve a83804a29a Extensive changes to the way code generation occurs for function 
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

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".

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!

Vikram S. Adve 3e54d6c3be Major bug fix: spill code for an instruction in a delay slot was 
merrily being inserted before/after the instruction!

Vikram S. Adve ed2df3ecf8 Live ranges for Return value and return address of a Call are now 
created here, simply by handling all implicit operands (which should
have been done anyway).

llvm-svn: 3969
 2002-09-28 17:05:22 +00:00
Vikram S. Adve 8fef3b8033 Fixed incorrect assertion: spill code for function ptr should be 
handled like normal operands, not like other call arguments.

Vikram S. Adve 5cc5d4b19a Add method IGNode::getCombinedDegree to count the sum of the degrees

llvm-svn: 3848
 2002-09-20 00:55:04 +00:00
Vikram S. Adve e008b2d62e Allow copy coalescing in more cases: if sum of node degrees is more than 
than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.
Add method IGNode::getCombinedDegree to count excluding duplicates.
