Vikram S. Adve 9a672d17ae This file implements a pass that automatically parallelizes a program,
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program

llvm-svn: 4104
2002-10-09 23:16:04 +00:00
Chris Lattner 013eca003a Almost a complete rewrite of FunctionResolution to now resolve functions
and global variables.

This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll
And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c

Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced.  This
is more of an infrastructure problem than anything.

Chris Lattner 736709feda - Checkin LARGE number of Changes to CEE pass that will make it much more
powerful, but that are largely disabled.  The basic idea here is that it
    is trying to forward branches across basic blocks that have PHI nodes in
    it, which are crucial to be able to handle cases like whet.ll.
    Unfortunately we are not updating SSA correctly, causing sim.c to die, and I
    don't have time to fix the regression now, so I must disable the
    functionality.

llvm-svn: 3980
2002-09-29 22:26:07 +00:00
Chris Lattner 6443769b34 Hoist the contents of Loops in depth first order in the dominator tree,
rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!

Chris Lattner 33fca976ee * Fix bug: test/Regression/Transforms/ADCE/2002-07-17-AssertionFailure.ll
which was caused by us not running the "drop references of dead
  instructions" code when there were no basic blocks that were dead.

  We still don't want to do some of the stuff we do if there are dead
  basic blocks, but we DO want to drop references of dead instructions,
  so we factor the common code out to a new method.
