(0 && "error").  Rough consensus seems to be that g++ *should* be diagnosing
this because the pointer makes it not an ICE in c++03.  Everyone agrees that
the current standard is silly and null-pointer-ness should not be based on
ICE-ness.  Excellent fight scene in Act II, denouement weak, two stars.

No testcase yet - it seems we're exposing generic codegen bugs.

Reduce (cmp 0, and_su (foo, bar)) into (bit foo, bar). This saves extra instruction. Patch inspired by Brian Lucas!

MachineBasicBlock::canFallThrough(), which is target-independent and more
thorough.

Minor optimization: when doing eq/ne comparions and RHS is a constant - swap operands, this will allow us to fold imm into comparison.

Move DebugInfo checks into EmitComments and remove them from
target-specific AsmPrinters.  Not all comments need DebugInfo.

Re-enable the line numbers comment test.

llvm-svn: 88697

Make the MachineFunction argument of getFrameRegister const.

This also fixes a build error.

llvm-svn: 87027

Add a bool flag to StackObjects telling whether they reference spill
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..

This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

bunch of associated comments, because it doesn't have anything to do
with DAGs or scheduling. This is another step in decoupling MachineInstr
emitting from scheduling.
