Eli Friedman ae8161e774 Fix AliasSetTracker so that it doesn't make any assumptions about instructions it doesn't know about (like the atomic instructions I'm adding).

Eli Friedman 17822fcde9 PR9604; try to deal with RAUW updates correctly in the AST. I'm not convinced 
it's completely safe to cache the AST across LICM runs even with this fix,
but this fix can't hurt.

Dan Gohman f4c5fe73be Change AliasAnalysis and its clients to use uint64_t instead of unsigned 
for representing object sizes, for consistency with other parts of LLVM.

Owen Anderson 6c18d1aac0 Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which 
must be called in the pass's constructor.  This function uses static dependency declarations to recursively initialize
the pass's dependencies.

Clients that only create passes through the createFooPass() APIs will require no changes.  Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.

I have tested this with all standard configurations of clang and llvm-gcc on Darwin.  It is possible that there are problems
with the static dependencies that will only be visible with non-standard options.  If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

Dan Gohman e4a82e2f21 Make the representation of AliasSets explicitly differentiate 
between "not known yet" and "known no tbaa info" so that it
can merge them properly.

Owen Anderson 8ac477ffb5 Begin adding static dependence information to passes, which will allow us to 
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

Chris Lattner f58382ed87 two changes: 1) make AliasSet hold the list of call sites with an 
assertingvh so we get a violent explosion if the pointer dangles.

2) Fix AliasSetTracker::deleteValue to remove call sites with
   by-pointer comparisons instead of by-alias queries.  Using
   findAliasSetForCallSite can cause alias sets to get merged
   when they shouldn't, and can also miss alias sets when the
   call is readonly.

#2 fixes PR6889, which only repros with a .c file :(

 2010-08-29 18:42:23 +00:00
Chris Lattner dc8070ed6d when merging two alias sets, the result set is volatile if either 
of the sets is volatile.  We were dropping the volatile bit of the
merged in set, leading (luckily) to assertions in cases like 
PR7535.  I cannot produce a testcase that repros with opt, but this
is obviously correct.

Dan Gohman 5442c71f2e 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.

Chris Lattner 88874ec60a 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.

Nick Lewycky 02d5f77d26 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.

Torok Edwin fbcc663cbf 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").

llvm-svn: 75640
 2009-07-14 16:55:14 +00:00
Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
