Chris Lattner 97c9f20c52 simplify AnalysisGroup registration, eliminating one typeid call. 
llvm-svn: 29932
 2006-08-28 00:42:29 +00:00
Chris Lattner c2d3d3112e eliminate RegisterOpt. It does the same thing as RegisterPass. 
llvm-svn: 29925
 2006-08-27 22:42:52 +00:00
Chris Lattner 3c9b2420df Eliminate RegisterAnalysis. RegisterPass now does all that is necessary.

Chris Lattner 5de3b8b262 Change the callgraph representation to store the callsite along with the 
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

Jim Laskey f7300b2706 It was pointed out that DEBUG() is only available with -debug.

 2006-07-11 18:25:13 +00:00
Jim Laskey c3d341ea98 Ensure that dump calls that are associated with asserts are removed from 
non-debug build.

Reid Spencer be535661cc For PR780: 
1. Fix the macros in IncludeFile.h to put everything in the llvm namespace
2. Replace the previous explicit mechanism in all the .h and .cpp files
   with the macros in IncludeFile.h
This gets us a consistent mechanism throughout LLVM for ensuring linkage.
Next step is to make sure its used in enough places.

Reid Spencer 5861659a1e Change from using a stub function to a stub variable for passing to the 
IncludeFile hack to ensure linkage of analysis passes. This works around
some -pedantic warnings about assigning an object to a function.

llvm-svn: 28546
 2006-05-29 23:39:48 +00:00
Andrew Lenharth e465381401 Since there was interest on the mailing list, this is a utility pass that 
uses DSA to make find targets of calls.  It provides a very convinient
interface to DSA results to do things with indirect calls, such as
write a devirtualizer (which I have and may commit one of these days).

Chris Lattner be19877731 Separate the call graph implementation from its interface. This implements 
the rough idea sketched out in http://nondot.org/sabre/LLVMNotes/CallGraphClass.txt,
allowing new spiffy implementations of the callgraph interface to be built.

Many thanks to Saem Ghani for contributing this!
