f9f37fc52c eliminate use of getNode that takes vector of valuetypes.

2fa6d3b1fc Add a new getNode() method that takes a pointer to an already-intern'd list
of value-type nodes.  This avoids having to do mallocs for std::vectors of
valuetypes when a node returns more than one type.

kimwitu, but seems like a good idea from a "avoid performance cliffs" standpoint :)

3bb4657488 Don't attempt to split subloops out of a loop with a huge number of backedges.
Not only will this take huge amounts of compile time, the resultant loop nests
won't be useful for optimization.  This reduces loopsimplify time on
Transforms/LoopSimplify/2006-08-11-LoopSimplifyLongTime.ll from ~32s to ~0.4s
with a debug build of llvm on a 2.7Ghz G5.

69b3992154 Make Loop::getExitBlocks significantly faster for large loops. Instead of
pounding on Loop::contains (which is O(n) in the size of the loop), use a
sorted vector, which is O(log(N)) for each query.  This speeds up Duraid's
horrible testcase from ~72s to ~31s in a debug build.

fa78946482 Reimplement the loopsimplify code which deletes edges from unreachable
blocks that target loop blocks.

Before, the code was run once per loop, and depended on the number of
predecessors each block in the loop had.  Unfortunately, scanning preds can
be really slow when huge numbers of phis exist or when phis with huge numbers
of inputs exist.

Now, the code is run once per function and scans successors instead of preds,
which is far faster.  In addition, the new code is simpler and is goto free,
woo.

This change speeds up a nasty testcase Duraid provided me from taking hours to
taking ~72s with a debug build.  The functionality this implements is already
tested in the testsuite as Transforms/CodeExtractor/2004-03-13-LoopExtractorCrash.ll.

bd564bfc63 Start eliminating temporary vectors used to create DAG nodes. Instead, pass
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

05445e30aa Make this example pass use some things from lib/Support (EscapeString,
SlowOperatingInfo, Statistics). Besides providing an example of how to
use these facilities, it also serves to debug problems with runtime linking
when dlopening a loadable module. These three support facilities exercise
different combinations of Text/Weak Weak/Text and Text/Text linking
between the executable and the module.

42fe455d37 For PR780:
1. Change the usage of LOADABLE_MODULE so that it implies all the things
   necessary to make a loadable module. This reduces the user's burdern to
   get a loadable module correctly built.
2. Document the usage of LOADABLE_MODULE in the MakefileGuide
3. Adjust the makefile for lib/Transforms/Hello to use the new specification
   for building loadable modules
4. Adjust the sample project to not attempt to build a shared library for
   its little library. This was just wasteful and not instructive at all.

eliminates a bunch of std::map's in the SelectionDAG, replacing them with a

hashtable never resizes.  That said, this still speeds up llc 20% on kimwitu++

a8e80c5188 Make the removal of files use Path::eraseFromDisk just like it does for
the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes.  This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.

7e79b3898d Changes:
1. Update an obsolete comment.
  2. Make the sorting by base an explicit (though still N^2) step, so
     that the code is more clear on what it is doing.
  3. Partition uses so that uses inside the loop are handled before uses
     outside the loop.

Note that none of these changes currently changes the code inserted by LSR,
but they are a stepping stone to getting there.

This code is the result of some crazy pair programming with Nate. :)

d41ae8bc0c Replace the SSA update code in LCSSA with a bottom-up approach instead of a top
down approach, inspired by discussions with Tanya.

This approach is significantly faster, because it does not need dominator
frontiers and it does not insert extraneous unused PHI nodes.  For example, on
252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest
pass in gccas) from 9.14s to 0.74s on my G5.  This code is also slightly smaller
and significantly simpler than the old code.

Amusingly, in a normal Release build (which includes the
"assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA
is in LCSSA form is actually slower than the LCSSA transformation pass
itself on 252.eon.  I will see if Loop::isLCSSAForm can be sped up next.

to its proper form.

55fc28076f - Refactor the code that resolve basic block references to a TargetJITInfo
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

d85340f4ec Change the callgraph representation to store the callsite along with the
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.
