nodes.  This allows it to do fairly general phi insertion if a 
load from a pointer global wants to be SRAd but the load is used
by (recursive) phi nodes.  This fixes a pessimization on ppc
introduced by Load PRE.

llvm-svn: 61123

temporary workaround for an obscure bug. When node cloning is
used, it is possible that more SUnits will be created, and
if the SUnits std::vector has to reallocate, it will
invalidate all the graph edges.

llvm-svn: 61122

Depth and Height members directly, as they may not be
current.

DAGTypeLegalizer::ExpandShiftWithKnownAmountBit.

In terms of restoring the optimization, the best fix here isn't 
obvious... any ideas?

Add (error) and (empty).

an IV are outside the loop.  Some cosmetics; no
functional change.

Add code to renumber split intervals into new vregs.  This is disabled for now until I finish working out some iterator invalidation issues.

ensure they are transformable.

consistently for deleting branches.  In addition to being slightly 
more readable, this makes SimplifyCFG a bit better 
about cleaning up after itself when it makes conditions unused.

eliminates the need for the CritialAntiDep DenseMap.

llvm-svn: 61094

different offsets within the same stack slot.

llvm-svn: 61093

We have decided not to support inline asm where an output operand with a matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ). SelectionDAGBuild will catch these and exit with an error.

visited set before they are used.  If used, their blocks need to be
added to the visited set so that subsequent queries don't use conflicting
pointer values in the cache result blocks.

corner cases are outside the primary aim of this pass.

variables.

latency computation code that is no longer needed with the
new method for handling latencies.

llvm-svn: 61074

computation code. Also, avoid adding output-depenency edges when both
defs are dead, which frequently happens with EFLAGS defs.

Compute Depth and Height lazily, and always in terms of edge latency
values. For the schedulers that don't care about latency, edge latencies
are set to 1.

Eliminate Cycle and CycleBound, and LatencyPriorityQueue's Latencies array.
These are all subsumed by the Depth and Height fields.

* Added code-region markings to code sections to make them stand out
* Added pre.doc_code class to llvm.css to simplify marking code regions

llvm-svn: 61072

* Converted absolute links to llvm.org/docs to relative links
* Fixed spelling and s/;/:/, as needed
