Brian Gaeke 2ad3501d3f brg 
InstSelectSimple.cpp: Refactor out conversion of byte, short -> int
  from visitReturnInst() to new method, promote32().
 Use it in both visitReturnInst() and visitCallInst().

llvm-svn: 4839
 2002-11-30 11:57:28 +00:00
Brian Gaeke 23953e0f8a brg 
InstSelectSimple.cpp: First draft of visitCallInst method, handling
 int/float args.
X86InstrInfo.def: Add entries for CALL with 32-bit pc relative arg, and
 PUSH with 32-bit reg arg.

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.

Vikram S. Adve 2d2303db22 Fix logical error in TD pass: we should clear Mod/Ref bits of each caller 
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

llvm-svn: 4836
 2002-11-27 17:41:13 +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
Vikram S. Adve 19b3303f3d (1) Bug fix that was causing nodes with dangling references to be freed. 
We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

Brian Gaeke 4ba2cb110a brg 
InstSelectSimple.cpp: Add some comments that say what I'm going to do for
 calls and casts.

 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.
