Chris Lattner 75742e532a Iteration is required for some cases, even if they don't occur in crafty.

Chris Lattner 5a56d30906 When joining two intervals where the RHS is really simple, use a light-weight 
method for joining the live ranges instead of the fully-general one.

Evan Cheng 1f15185cbc Another "cyclic DAG" test case.

Evan Cheng 2c4e0f120f Oops. Bad typo. Without the check of N1.hasOneUse() bad things can happen. 
Suppose the TokenFactor can reach the Op:

       [Load chain]
           ^
           |
         [Load]
         ^    ^
         |    |
        /      \-
       /         |
      /          [Op]
     /          ^ ^
     |        ..  |
     |       /    |
   [TokenFactor]  |
       ^          |
       |          |
        \        /
         \      /
         [Store]

If we move the Load below the TokenFactor, we would have created a cycle in
the DAG.

llvm-svn: 30025
 2006-09-01 18:45:22 +00:00
Evan Cheng 31c99969a9 Last check-in was a mistake... 
I've been told apple gcc version number is not guaranteed to increase
monotonically. Change the preprocess condition to make it less risky.

The configuration change is done during the middle 10.4 life cycle so we have
to check __APPLE_CC. For future OS X release, we should be able to assume
-fenable-cxa-atexit is the default.

Nick Lewycky f6f529d008 Don't confuse canonicalize and lookup. Fixes predsimplify.reg4.ll. Also

Evan Cheng 31305c45da DAG combiner fix for rotates. Previously the outer-most condition checks 
for ROTL availability. This prevents it from forming ROTR for targets that
has ROTR only.

Nick Lewycky 5f8f9af65c Move to using the EquivalenceClass ADT. Removes SynSets. 
If a branch's condition has become a ConstantBool, simplify it immediately.
Removing the edge saves work and exposes up more optimization opportunities
in the pass.

Chris Lattner 34434e97c9 Teach the coallescer to coallesce live intervals joined by an arbitrary 
number of copies, potentially defining live ranges that appear to have
differing value numbers that become identical when coallsced.  Among other
things, this fixes CodeGen/X86/shift-coalesce.ll and PR687.

- Clean up the code generated by tablegen:
  * AddToISelQueue now takes one argument.
  * ComplexPattern matching condition can now be shared.
  * Eliminate passing unnecessary arguments to emit routines.
  * Eliminate some unneeded SDOperand declarations in select routines.
  * Other minor clean ups.
- This reduces foot print slightly: X86ISelDAGToDAG.o is reduced from 971k
  to 823k.

Evan Cheng d7572fb234 Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The 
asm printer will print it as offset*4. e.g. bne cr0, $+8.

The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.
