Chris Lattner 2ec9de30cd Reserve space for PHI nodes when we read them in. This provides a VERY 
tasty 15% speedup on the testcase from Bill.

Chris Lattner e7691a4520 Major refactoring of the bytecode reader. This includes the following 
changes:
  * BytecodeReader::getType(...) used to return a null pointer
    on error.  This was only checked about half the time.  Now we convert
    it to throw an exception, and delete the half that checked for error.
    This was checked in before, but psmith crashed and lost the change :(
  * insertValue no longer returns -1 on error, so callers don't need to
    check for it.
  * Substantial rewrite of InstructionReader.cpp, to use more efficient,
    simpler, data structures.  This provides another 5% speedup.  This also
    makes the code much easier to read and understand.

Chris Lattner bd26abdc95 Significantly clean up parsing of instructions. This exceptionizes and 
simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

Chris Lattner 1e8addf890 Eliminate the instruction placeholder. Simplify a bunch of code. 
This results in no significant speedup, but does provide simpler code

 2003-10-09 06:14:26 +00:00
Chris Lattner 42dce1e365 Eliminate the old LateResolveValues data structure, replacing it with a 
new, simpler, ForwardReferences data structure.  This is just the first
simple replacement, subsequent changes will improve the code more.

This simple change improves the performance of loading a file from HDF5
(contributed by Bill) from 2.36s to 1.93s, a 22% improvement.  This
presumably has to do with the fact that we only create ONE placeholder for
a particular forward referenced values, and also may be because the data
structure is much simpler.

Chris Lattner a9c297c8ea Remove a dead method 
llvm-svn: 8978
 2003-10-09 05:25:34 +00:00
Chris Lattner abf6412c09 This patch substantially simplifies and cleans up handling of basic blocks 
in the bytecode parser.  Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values.  For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.

This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s.  More speedups to
follow later.

Chris Lattner 0bbbe5d4c8 Use a set to keep track of which edges have been noticed as executable already 
to avoid reprocessing PHI nodes needlessly.  This speeds up the big bad PHI
testcase 43%: from 104.9826 to 73.5157s

llvm-svn: 8963
 2003-10-08 16:21:03 +00:00
Chris Lattner 71ac22ffb5 Avoid building data structures we don't really need. This improves the runtime 
of a test that Bill Wendling sent me from 228.5s to 105s.  Obviously there is
more improvement to be had, but this is a nice speedup which should be "felt"
by many programs.

Alkis Evlogimenos 5f1f337d95 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}
