pattern which is broken (source and address swapped).

pattern, not i64.

llvm-svn: 97956

example, this:

(set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin))

is ambiguous because DPR contains both f64 and v2f32.  tblgen
currently accidentally picks f64 because it's first in the 
regclass.

needs to be majorly refactored, but this spot bugfix allows
things like:

 def vmrghw_shuffle : PatFrag<(ops node:$lhs, node:$rhs),
                             (vector_shuffle (v4i32 node:$lhs), node:$rhs), [{

Add a missing interface to be able to call findNearestCommonDominator
for a PostDominanceTree. The function itself is already implemented in
DominatorTreeBase. The interface however was only added to the
DominatorTree class, but not the PostDominatorClass.

Now it will factor things like this:

CheckType i32
  ...
CheckOpcode ISD::AND
  CheckType i64
  ...

into:

SwitchType:
  i32: ...
  i64:
    CheckOpcode ISD::AND
    ...

This shrinks hte table by a few bytes, nothing spectacular.

for CheckValueTypeMatcher.  The isContradictory implementation
helps us factor better, shrinking x86 table from 79144 -> 78896
bytes.

Patch by John Tytgat!

llvm-svn: 97886

We cannot use a normal call here since it has extra unmodelled side
effects (it changes stack pointer). This should fix PR5292.

Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though).

This fixes PR6349

before we try to optimize.

llvm-svn: 97876

out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

Log:
Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.

Modified:
   llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp
   llvm/trunk/test/Transforms/InstCombine/objsize.ll

It appears to be causing swb and nightly test failures.
