Brian Gaeke e74543584a include/llvm/CodeGen/MachineInstrBuilder.h: Add addClobber() inline 
convenience method.  Fix typo in comment.
lib/Target/X86/InstSelectSimple.cpp: Explicitly specify some implicit uses.
 Use MOVZX/MOVSX instead of MOV instructions with sign extend instructions.
 Take out LEAVE instructions.
 32-bit IDIV and DIV use CDQ, not CWQ (CWQ is a typo).
 Fix typo in comment and remove some FIXME comments.
lib/Target/X86/Printer.cpp: Include X86InstrInfo.h and llvm/Function.h.
 Add some simple code to Printer::runOnFunction to iterate over
  MachineBasicBlocks and call X86InstrInfo::print().
lib/Target/X86/X86InstrInfo.def: Make some more instructions with
 implicit defs "Void".  Add more sign/zero extending "move" insns
 (movsx, movzx).

Vikram S. Adve 16eac628f4 Pass to compute various statisics related to DSGraphs. 
For now, this just computes the #indirect call sites and
the avg. #callees per indirect call site (actually it prints
both totals and the average is their ratio).

Chris Lattner ccc27ecd35 Inline graphs from outside the SCC into the SCC before SCC resolution starts 
llvm-svn: 4701
 2002-11-12 15:58:08 +00:00
Chris Lattner dcb4ac9594 Fix two bugs: 
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.

Chris Lattner 7b61563d99 * Dramatically rework liveness evaluation. 
* Implement the first step of the Globals graph: Deleting nodes from function
  graphs.  In practice, these nodes need to be moved to the globals graph, but
  this will be taken care of later.  Note that the graphs computed right now are
  not strictly correct!

Chris Lattner 3b83d797d6 * Bottom-Up graphs print the Aux call vector 
* Significantly improve DEBUG output
* Aggressively fold calls together if we inlined a graph that provides
  call nodes.
* Add a bailout if the current graph has over 200 call nodes in it, this is
  a really whacky case that should never happen.

Chris Lattner 715a3a3b5c eliminate the ability to remove global nodes from deadNodeElminate... for now. 
This slows stuff down a bit, but it should get much better before it gets any
worse.

Chris Lattner be46569ba1 Fold arrays down to a single element. This causes huge wins on some benchmarks 
for example: 197.parser (64M->14M), 164.gzip (14M->2.7M).  The actual graphs

 2002-11-07 07:12:23 +00:00
Chris Lattner 5e865cdbe2 Instead of using a bool that constant has to be explained, use a self 
explanitory enum instead.

llvm-svn: 4600
 2002-11-07 07:06:20 +00:00
Chris Lattner df307e6fd0 Implement a new mergeInGraph method, which basically factors code out of 
the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.

Chris Lattner a7b0d4eb08 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

Chris Lattner 7d5f19886d This fixes all kinds of problems with array handling. There are still bugs to 
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.

Chris Lattner 49f4242d2b - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization

Chris Lattner ce64eddb71 - Two minor improvements to the MachineInstr class to reduce footprint and

Chris Lattner 51a2c3cc2d - Make sure to only keep track of mappings that the TD pass may need in the

    disabled.

Chris Lattner 78c1e7d83c As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and

CallInst and the caller Function.  The special-purpose class
