Reapply r110396, with fixes to appease the Linux buildbot gods.

llvm-svn: 110460

Revert r110396 to fix buildbots.

llvm-svn: 110410

Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static
ID member as the sole unique type identifier. Clean up APIs related to this change.

llvm-svn: 110396

Thread const correctness through a bunch of AliasAnalysis interfaces and
eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for i

Thread const correctness through a bunch of AliasAnalysis interfaces and
eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

simplify

llvm-svn: 109577

Fix batch of converting RegisterPass<> to INTIALIZE_PASS().

llvm-svn: 109045

Change dbgs() back to errs() as Chris requested.

llvm-svn: 92073

Convert debug messages to use dbgs(). Generally this means
s/errs/dbgs/g except for certain special cases.

llvm-svn: 92029

Remove the AliasAnalysis::getMustAliases method, which is dead.

The hasNoModRefInfoForCalls isn't worth it as a filter because
basicaa provides m/r info and everything chains to it, so remove
it.

remove unneeded checks of isFreeCall

Rename MallocFreeHelper as MemoryBuiltins

llvm-svn: 85286

Rename MallocHelper as MallocFreeHelper, since it now also identifies calls to free()

llvm-svn: 85181

Remove FreeInst.
Remove LowerAllocations pass.
Update some more passes to treate free calls just like they were treating FreeInst.

llvm-svn: 85176

Remove includes of Support/Compiler.h that are no longer needed after the
VISIBILITY_HIDDEN removal.

llvm-svn: 85043

Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces.
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit

eliminate the std::ostream form of WriteAsOperand and update clients.
This also updates dominator related stuff.

llvm-svn: 79825

Fix some problems with ASTCallbackVH in its use as a DenseMap key.

llvm-svn: 77696

Use CallbackVH in AliasSetTracker to avoid getting stuck with
dangling Value*s.

llvm-svn: 77623

Make AliasAnalysis and related classes use
getAnalysisIfAvailable<TargetData>().

This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.

llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

getEntryFor() may invalidate DenseMap iterator.
Walking an invalidated iterator is not a good idea.

llvm-svn: 68047

reimplement AliasSetTracker in terms of DenseMap instead of hash_map,
hopefully no functionality change.

llvm-svn: 66398

Ignore the debug info intrinsics when adding instructions into alias sets.

llvm-svn: 65934

Tidy up several unbeseeming casts from pointer to intptr_t.
