Chris Lattner 45d67d6ea7 Initial implementation of Loop invariant memory->scalar promotion 
llvm-svn: 5613
 2003-02-24 03:52:32 +00:00
Chris Lattner 26f159046c Split mem2reg promotion into two parts: a function which does the work, and 
a pass which wraps the function.  This allows other passes to use the functionality

Chris Lattner 57c8d99bbd 4 new transformations: 
* X*C + X --> X * (C+1)
  * X + X*C --> X * (C+1)
  * X - X*C --> X * (1-C)
  * X*C - X --> X * (C-1)

Chris Lattner 3082c5a070 Add a variety of new transformations: 
* A & ~A == 0
  * A / (2^c) == A >> c  if unsigned
  * 0 / A == 0
  * 1.0 * A == A
  * A * (2^c) == A << c
  * A ^ ~A == -1
  * A | ~A == -1
  * 0 % X = 0
  * A % (2^c) == A & (c-1) if unsigned
  * A - (A & B) == A & ~B
  * -1 - A == ~A

Vikram S. Adve d9676ed983 External routines used to identify Cilk operations inserted by the 
parallelization pass.

llvm-svn: 4965
 2002-12-10 13:08:48 +00:00
Vikram S. Adve c864ab1e33 This file implements the function DemoteRegToStack(), which takes a 
virtual register computed by an Instruction& X and replaces it with
a slot in the stack frame, allocated via alloca.

llvm-svn: 4964
 2002-12-10 13:07:58 +00:00
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
because it does not attempt to optimize their placement.
