Misha Brukman 1af9bebcda storeReg2RegOffset() and loadRegOffset2Reg() now take the iterator by value 
instead of by reference, since they return the modified iterator.

llvm-svn: 4914
 2002-12-04 17:14:13 +00:00
Misha Brukman 0d28502c32 Moved buildReg2RegClassMap() into from X86RegisterInfo to MRegisterInfo, since 
it is target-independent.

well as building a map from a physical register to its register class.

Chris Lattner 23f0e10a9a The hopefully final version of addPassesToEmitMachineCode which does not

 2002-12-02 21:00:50 +00:00
Vikram S. Adve cb8b5af572 Several fixes: 
(1) Applied patch from Casey to implement iterator::operator= correctly:
    it should use a pointer, not a reference.
(2) Added operators == and !=, and method all().
(3) Important bug fix: excess bits need to be ignored in operations
    like ==, count(), and all().  We do this by ensuring excess bits
    in the last bitset are always 0.

llvm-svn: 4837
 2002-11-27 17:46:38 +00:00
Vikram S. Adve 0b5b784922 Added flags to CloneFlags to strip/keep Mod/Ref bits when cloning a graph. 
llvm-svn: 4835
 2002-11-27 17:39:37 +00:00
Vikram S. Adve 9409087108 No longer need local graph to find call sites. 
Also some major fixes within IPModRef.cpp.

llvm-svn: 4834
 2002-11-27 17:38:56 +00:00
Misha Brukman ec6b8e9fad Added virtual functions for storing and retrieving values from the stack. 
llvm-svn: 4824
 2002-11-22 22:41:23 +00:00
Misha Brukman 5bed2faf6b Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

Misha Brukman 31457f066d Set SSARegMap to NULL after deleting it.

Chris Lattner a35d7412c6 Cloning stuff doesn't modify the source module 
llvm-svn: 4787
 2002-11-20 20:22:58 +00:00
Misha Brukman 45f6b8410e MRegisterInfo.h - Added prototypes for functions we need to map a register to 
an appropriate TargetRegisterClass, also adds TargetRegisterClass definition.
TargetMachine.h - speling.

Chris Lattner 98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

llvm-svn: 4779
 2002-11-20 18:36:02 +00:00
Chris Lattner b251c3d727 Eliminate the concept of a deferred symbol table. The optimization really isn't, 
and it causes obscure bugs to show up in passes.

llvm-svn: 4777
 2002-11-20 18:07:48 +00:00
Misha Brukman a5381b4932 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which 
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.

llvm-svn: 4720
 2002-11-17 22:14:22 +00:00
Chris Lattner 76a95ecad0 Convert to use an enum to access def/use/use&def information. These make 
reading code much easier than just seeing "true, false" especially when
default parameters default one but not both arguments.

Brian Gaeke e74543584a include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline 
convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).
lib/Target/X86/X86RegisterInfo.def: Add EFLAGS as a register.
