Dan Gohman 434a3ca8e9 Don't charge the full latency for anti and output dependencies. This is
an area where eventually it would be good to use target-dependent
information.

Ted Kremenek fff9f4aaaf BasicConstraintManager:
- Fix nonsensical logic in AssumeSymGE. When comparing 'sym >= constant' and the
  constant is the maximum integer value, add the constraint that 'sym ==
  constant' when the path is deemed feasible.  All other cases are feasible.
- Improve AssumeSymGT. When comparing 'sym > constant' and constant is the
  maximum integer value we know the path is infeasible.
- Add test case for this enhancement to AssumeSymGT.

  'sym < constant' and constant is the minimum integer value we know the
  path is infeasible.

parts, and add target-independent code to add/preserve
MachineMemOperands.

Dan Gohman 78407ac8e5 Extend X86's addFrameReference to add a MachineMemOperand for
the frame reference. This will help post-RA scheduling determine
that spills to distinct stack slots are independent.

Chris Lattner 350fc5721d testcase for br undef folding.
llvm-svn: 60471
2008-12-03 07:48:27 +00:00
Chris Lattner 595c7279bd Teach jump threading some more simple tricks:
1) have it fold "br undef", which does occur with
   surprising frequency as jump threading iterates.
2) teach j-t to delete dead blocks.  This removes the successor
   edges, reducing the in-edges of other blocks, allowing 
   recursive simplification.
3) Fold things like:
     br COND, BBX, BBY
  BBX:
     br COND, BBZ, BBW

   which also happens because jump threading iterates.

Chris Lattner 50532410d1 don't spew tons of stuff to the output. This testcase is *not* for
loop deletion (it is for a ton of passes), which is very bad.

Chris Lattner 7eb270ed03 Rename DeleteBlockIfDead to DeleteDeadBlock and make it
unconditionally delete the block.  All likely clients will
do the checking anyway.

Dan Gohman cc78cdf275 Mark x86's V_SET0 and V_SETALLONES with isSimpleLoad, and teach X86's
foldMemoryOperand how to "fold" them, by converting them into constant-pool
loads. When they aren't folded, they use xorps/cmpeqd, but for example when
register pressure is high, they may now be folded as memory operands, which
reduces register pressure.

Also, mark V_SET0 isAsCheapAsAMove so that two-address-elimination will
remat it instead of copying zeros around (V_SETALLONES was already marked).

Dan Gohman ae3ba45eb2 Add a sanity-check to tablegen to catch the case where isSimpleLoad
is set but mayLoad is not set. Fix all the problems this turned up.

Change code to not use isSimpleLoad instead of mayLoad unless it
really wants isSimpleLoad.

Dan Gohman 5d3d1f69e1 Fix byval arguments in the fastcc calling convention. The fastcc convention
delegates to the regular x86-32 convention which handles byval, but only
after it handles a few cases, and it's necessary to handle byval before
handling those cases. This fixes PR3122 (and rdar://6400815), llvm-gcc
miscompiling LLVM.
