Misha Brukman f0971994ca Simple arithmetic loop-based test case for modulo scheduling. 
llvm-svn: 5774
 2003-04-10 22:01:15 +00:00
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.

llvm-svn: 5750
 2003-03-19 20:57:22 +00:00
Chris Lattner 428bf5abc9 Changes to the V2 bytecode format: 
- Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Writer changes:
  - We now explictly encode versioning information in the bytecode files.
  - This allows new code to read bytecode files produced by old code, but
    new bytecode files can have enhancements such as the above.  Although this
    makes the reader a bit more complex (having to deal with old formats), the
    writer only needs to be able to produce the most recent version.

llvm-svn: 5749
 2003-03-19 20:56:46 +00:00
Chris Lattner 5db8194ca9 * Bug fixes: 
- Fix problems where the constant table would not get updated when
    resolving constants causes other constants to change.

Changes to the V2 bytecode format
  - Null values are implicitly encoded instead of explicitly, this makes
    things more compact!
  - More compactly represent ConstantPointerRefs
  - Bytecode files are represented as:
      Header|GlobalTypes|GlobalVars/Function Protos|Constants|Functions|SymTab
    instead of
      Header|GlobalTypes|Constants|GlobalVars/Function Protos|Functions|SymTab
    which makes a lot of things simpler.

Changes to the reader:
  - Function loading code is much simpler.  We now no longer make function
    PlaceHolderHelper objects to be replaced with real functions.

Chris Lattner bb74e2284a Generalize not and neg comparison testers to allow constant to be considered not'able and neg'able. This 
allows optimization of this:
int %test4(int %A, int %B) {
        %a = xor int %A, -1
        %c = and int %a, 5    ; 5 = ~c2
        %d = xor int %c, -1
        ret int %d
}

into this:
int %test4(int %A, int %B) {            ; No predecessors!
        %c.demorgan = or int %A, -6             ; <int> [#uses=1]
