Jakob Stoklund Olesen bb4bece211 Add test case with randomly ordered insertions, massive coalescing. 
Implement iterator::erase() in a simple version that erases nodes when they
become empty, but doesn't try to redistribute elements among siblings for better
packing.

Handle coalescing across leaf nodes which may require erasing entries.

Owen Anderson 8ba5f39f70 Second attempt at fixing the performance regressions introduced 
by my recent GVN improvement.  Looking through a single layer of
PHI nodes when attempting to sink GEPs, we need to iteratively
look through arbitrary PHI nests.

Daniel Dunbar 762bf86919 ADT/InMemoryStruct: Add an experimental helper class intended for use in 
situations where on the common path an API can return a pointer to some direct
memory, but which on an exceptional path may need to return a pointer to a
temporary struct.

Benjamin Kramer 9610ea943c BitVector tweaks. 
- Double the vector's capacity when growing to avoid unneeccesary reallocation.
- Do the reallocation with realloc(3) which can expand the memory in place.

Jakob Stoklund Olesen a12095d26d Move tree navigation to a new Path class that doesn't have to be a template. 
The path also holds a reference to the root node, and that allows important
iterator accessors like start() and stop() to have no conditional code. (When
the compiler is clever enough to remove it.)

Michael J. Spencer 96bcfcf2c2 Path Version 2. 
Based on TR2/boost filesystem (v3) API, but modified to remove exceptions.

Do not include this file directly, when it is ready, it will be included by

Ted Kremenek 1ef52416c7 Tweak ImmutableMap/ImmutableSet/ImmutableList APIs 
to use lowercase letters for the start of most
method names and to replace some method names
with more descriptive names (e.g., "getLeft()"
instead of "Left()").  No real functionality
change.

Jakob Stoklund Olesen 00430319a8 Generalize overflowLeaf to also handle overflows in branch nodes. 
This doesn't quite work yet because the calls to treeDecrement and treeIncrement
operate at the leaf level, not on pathNode(Level) as required.

 2010-11-23 10:50:08 +00:00
Duncan Sands 763dec0ab8 Clarify that constant folding of instructions applies when all operands 
are constant.  There was in fact one exception to this (phi nodes) - so
remove that exception (InstructionSimplify handles this so there should
be no loss).
