Reid Spencer eb04d9bcb4 Add #include <iostream> since Value.h does not #include it any more.

Brian Gaeke a411e07db0 Include SparcV9RegInfo.h instead of TargetRegInfo.h. This serves as a bit of 
documentation that this module needs to be made independent of the
register file description of the current target.

Alkis Evlogimenos 8cdd0215bf Remove getAllocatedRegNum(). Use getReg() instead. 
llvm-svn: 11393
 2004-02-13 21:01:20 +00:00
Alkis Evlogimenos 80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

Brian Gaeke 0c3de446f6 getOpCode() --> getOpcode(). 
llvm-svn: 11339
 2004-02-12 01:34:05 +00:00
Brian Gaeke 312e3a28d2 Make SchedGraph::dump() use SchedGraphNodeCommon's const_iterator 
instead of randomly groping about inside its outEdges array.
Make SchedGraph::addDummyEdges() use getNumOutEdges() instead of
outEdges.size().
Get rid of ifdefed-out code in SchedGraph::buildGraph().

Alkis Evlogimenos aaba4639f8 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

John Criswell 482202a601 Added LLVM project notice to the top of every C++ source file. 
Header files will be on the way.

Vikram S. Adve fa1dde06aa A def. operand of a machine instruction may be an ordinary Value*, 
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*.

llvm-svn: 7052
 2003-07-02 01:16:01 +00:00
Vikram S. Adve 465f9b6738 Changes to allow explicit physical register arguments that have been 
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.

llvm-svn: 6467
 2003-05-31 07:37:05 +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".

Vikram S. Adve 19c55db0d9 A single MachineInstr operand may now be both a def and a use, 
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".

llvm-svn: 2397
 2002-04-29 17:42:12 +00:00
Chris Lattner 6c1a58d6ba Clean up the ownership model a bit so that nodes actually get deleted more 
frequently. This still leaks edges quite a bit, but it leaks no nodes
(I think).

llvm-svn: 2190
 2002-04-09 05:15:33 +00:00
Chris Lattner 62b7fd136e Change references to the Method class to be references to the Function 
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

Chris Lattner 5de2204fe8 Create a new #include "Support/..." directory structure to move things 
from "llvm/Support/..." that are not llvm dependant.

Move files and fix #includes

 2001-11-26 18:56:52 +00:00
Vikram S. Adve 03fae5e5db Eliminate most uses of the machine instruction vector for each LLVM instr, 
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.

llvm-svn: 1269
 2001-11-12 18:53:43 +00:00
Vikram S. Adve dff0a891c1 Major improvement to how nodes are built for a BB. 
LLVM instruction is no longer recorded in each node, but BB is.

llvm-svn: 1262
 2001-11-12 14:18:01 +00:00
Vikram S. Adve 6cd83556e6 Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

llvm-svn: 1254
 2001-11-11 01:23:27 +00:00
Vikram S. Adve 621b90440b Major change to how defs are found when adding dependences (they 
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.

llvm-svn: 1199
 2001-11-08 05:20:23 +00:00
Vikram S. Adve 596721384b Modified graph construction to use one pass to find all defs. 
Avoids having to handle some special cases that cause complex interactions
with instr. selection.

llvm-svn: 1138
 2001-11-05 04:04:23 +00:00
Vikram S. Adve df6913549a Add edges between call instructions and (a) load/store instructions, and 
(b) any instructions that use or set CC registers.  Whether or not the
latter are needed really should be machine-dependent.
