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.

Rename to addPPCallbacks since we're effectively adding a callback and maybe chaining it to an existing one

llvm-svn: 97913

llvm-svn: 97912

llvm-svn: 97911

Don't assert if PP already contains a valid PP callback. The PP can handle multiple callbacks (using PPChainedCallbacks)

(Rolling back r97906.)

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.

are lexically nested.  Othewise, we never end up recording semantically nested
classes.

llvm-svn: 97900

doesn't do this on any of the major platforms, and we don't really
support any of the platforms that do (nor will we actually handle
those headers well). Fixes PR6217; see PR6530 for details on what we
would need to do to support these platforms.

Patch by John Tytgat!

llvm-svn: 97886

as a "C++ Friendly" system header directory.  This fixes
PR6523.

llvm-svn: 97885

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

llvm-svn: 97884

llvm-svn: 97883

llvm-svn: 97882

Rename the new Iterator objects and raise an assertion instead of returning invalid objects when the key is out of range.

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

llvm-svn: 97877

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.
