undef in either the left or right operand.

right so there is no need to duplicate logic, just use the values the makefile
provides. 

Eliminate some redundnt -D options from the output.

Fix the help output so it fits on 80 cols.

llvm-svn: 38488

contains some of the defines but not all CPP flags.

llvm-svn: 38487

put into the CPP.Defines variable. Seems the convention was corrupted with
various changes made. It is important to get command line parameters into the
right variable because things like llvm-config and sub-makefiles depend on it.

When a node value is only used by a CopyToReg, use the user's dest. This should not be restricted to nodes that produce only a single value.

Move some key maps from std::map to DenseMap.  This improves the time to optimize Anton's testcase from 17.5s
to 15.7s.

llvm-svn: 38480

Use a cheaper test, delaying calling find_leader() until we know that it's necessary.  This improves
the time to optimize Anton's testcase from 21.1s to 17.6s.

in addition to the intrinsic forms. Add spill-folding entries for these new
instructions, and for the scalar min and max instrinsic instructions which
were missing. And add some preliminary ISelLowering code for using the new
non-intrinsic vector sqrt instruction, and fneg and fabs.

register ordering, for both physical and virtual registers. Update the PPC
target lowering for calls to expect registers for the call result to
already be in target order.

llvm-svn: 38471

Make the assignment operator for SmallPtrSet return a reference, and fix a long-standing bug in the copy
ctor while I'm at it.

Thanks to Chris Lattner for help with this patch.

updating it with calls to setIndexedLoadAction/setIndexedStoreAction,
which only update a few bits at a time. This avoids ostensible
undefined behavior of operationg on values which may be
trap-representations, and as a practical matter fixes errors from
valgrind, which doesn't track uninitialized memory with bit
granularity.
