Dan Gohman abd1709678 Minor whitespace cleanups.

 2009-06-24 14:49:00 +00:00
Dan Gohman f57bdb75d4 Simplify [su]max(MAX, n) to MAX. This comes up in loop tripcount 
computations in loops with multiple exits.

Adjust the testcase for PR4436 so that the relevant portion isn't
optimized away.

Dan Gohman 929fa7b0f4 When inserting code into a loop preheader, insert it before the 
terminator, instead of after the last phi. This fixes a bug
exposed by ScalarEvolution analyzing more kinds of loops.
This fixes PR4436.

Duncan Sands d1b5115986 Start sketching 2.6 release notes. This provides a 
place to note major API changes (I've noted the
getABITypeSize -> getAllocSize change).

 2009-06-24 04:47:54 +00:00
Chris Lattner bedf6c2995 add support for parsing and emitting .section directives. We can now parse 
things like:
.section __TEXT,__cstring,cstring_literals

 2009-06-24 04:43:34 +00:00
Chris Lattner 3f5738d599 add trivial support for passing label definitions through the MCStreamer. 
This is suboptimal in several aspects, see the commented out assertion.
I need to talk to Daniel about this.

Dan Gohman 5f71a2886a Add a testcase demoing some of ScalarEvolution's new trip count logic. 
llvm-svn: 74049
 2009-06-24 01:22:30 +00:00
Dan Gohman f19aeec3f5 Extend ScalarEvolution's multiple-exit support to compute exact 
trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

llvm-svn: 74042
 2009-06-24 00:55:55 +00:00
Dan Gohman f436bacb6b Move the special cases for constants out of getUnknown and into 
createSCEV. Also, recognize UndefValue in createSCEV.

Change getIntegerSCEV's comment to avoid mentioning FP types,
and re-implement it in terms of getConstant instead of getUnknown.

 2009-06-24 00:51:35 +00:00
Dan Gohman 8d7576e12c Use ScalarEvolution::getConstant instead of getUnknown to create 
SCEVConstants. This cleanup is a step toward letting getUnknown
be simpler.

Owen Anderson ecdab5406d Guard the listeners list. Unfortunately, this requires a real static rather 
than a managed static because other managed statics can (and do) access this
list in their destructors.  Yes, I know it's horrible.

Bob Wilson 5a495fea07 Provide InitializeAllTargets and InitializeNativeTarget functions in the

Change the "llvm/Config/Targets.def" header to use C-style comments to avoid
compile warnings.

Douglas Gregor b52fabb2a8 Start propagating template parameter lists to the right places to 
handle function templates. There's no actual code for function
templates yet, but at least we complain about typedef templates.
