| | | | | | instructions it doesn't know about (like the atomic instructions I'm adding). llvm-svn: 136198
* PR9604; try to deal with RAUW updates correctly in the AST. I'm not convincedEli Friedman2011-04-091-0/+4
| | | | | | | it's completely safe to cache the AST across LICM runs even with this fix, but this fix can't hurt. llvm-svn: 129198

* Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson2010-10-191-1/+3
| | | | | | | | | | | | | | | | | 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. llvm-svn: 116820
* Make the representation of AliasSets explicitly differentiateDan Gohman2010-10-181-2/+2
| | | | | | | between "not known yet" and "known no tbaa info" so that it can merge them properly. llvm-svn: 116767

* Make AliasSetTracker TBAA-aware, enabling TBAA-enabled LICM.Dan Gohman2010-10-181-24/+49
| | | | llvm-svn: 116743
* Begin adding static dependence information to passes, which will allow us toOwen Anderson2010-10-121-1/+4
| | | | | | | | | 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. llvm-svn: 116334

* two changes: 1) make AliasSet hold the list of call sites with anChris Lattner2010-08-291-14/+20
| | | | | | | | | | | | | | 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 :( llvm-svn: 112452
* when merging two alias sets, the result set is volatile if eitherChris Lattner2010-08-291-0/+1
| | | | | | | | | 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. llvm-svn: 112402

* Don't use PassInfo* as a type identifier for passes. Instead, use the ↵Owen Anderson2010-08-051-1/+1
| | | | | | | | 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 andDan Gohman2010-08-031-1/+1
| | | | | | | | | | | | 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. llvm-svn: 110155

| | | | | | | | The hasNoModRefInfoForCalls isn't worth it as a filter because basicaa provides m/r info and everything chains to it, so remove it. llvm-svn: 89599

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-1/+1
| | | | | | | | | 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
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-1/+2
| | | | | | | | | 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. llvm-svn: 75379
