Chris Lattner 1f0049c79c Allow constant folding of GEP instructions, even if we don't do a whole lot yet. 
Fold ConstExpr casts better
castToPointer shouldn't be forced to return a constantpointer

Misha Brukman dbea9cd4be Adding a simple test case in the hope that commit-diffs.pl will pick this up. 
llvm-svn: 5773
 2003-04-10 21:49:13 +00:00
Misha Brukman 3064bff740 Not only is this the first test case for ModuloScheduing, it's also the first 
test case for the CVS commit-diffs.pl script which should show the entire
contents of this file below:

Chris Lattner 18b1bf67b2 * Fix bug: Mem2Reg/2003-04-10-DFNotFound.ll 
* Make Mem2Reg assign version numbers now for renamed variables instead of
  .mem2reg suffixes.  This produces what people think of as SSA.

Chris Lattner 6371087a0e New testcase 
llvm-svn: 5770
 2003-04-10 19:21:07 +00:00
Misha Brukman a45606276d Fixed compilation errors, command-line argument declarations, cleaned up code to 
look nicer and removed useless stuff.

Also renamed a few variables, moved them into namespaces, converted outputting
to a file into a print to std::cerr with a DEBUG() guard, as all passes should
do anyway.

No functional changes have been made. However, this code now compiles.

llvm-svn: 5769
 2003-04-10 19:19:23 +00:00
Misha Brukman 218a732724 Made the code readable: 
* Lines must be wrapped at 80 chars. This is a hard limit.
* Consistent style on functions, braces, if, for, etc. Code must be readable.

No functional changes have been made, even though I added a new typedef.

llvm-svn: 5768
 2003-04-09 21:51:34 +00:00
Misha Brukman 61a9e7c901 Must use std::pair instead of just 'pair'.

Chris Lattner 8cf3b0969a Initial checkin of PRE tests 
llvm-svn: 5760
 2003-03-31 19:57:36 +00:00
Chris Lattner 9023155621 Initial checkin of PRE on LLVM. This implementation is still lacking in 
several ways:

 * Load expressions are not PRE'd well.  Alias Analysis should be used to
   get accurate information when computing anticipatibility.
 * The expression collection implementation does not handle PHI nodes properly,
   thus the implementation misses many opportunities to PRE.
 * This code could be sped up quite a bit

Despite these flaws, the code seems to work well, and handles PR's as one
would expect.
