* Introduce MetadataBase, a base class for MDString and MDNode.Devang Patel2009-07-221-12/+0
| | | | | | | | | | Derive MDString directly from MetadataBase. Introduce new bitcode block to hold metadata. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76759 91177308-0d34-0410-b5e6-96231b3b80d8
* reimplement Constant::ContainsRelocations as Chris Lattner2009-07-221-23/+24
| | | | | | | | | | | Constant::getRelocationInfo(), which has a much simpler to use API. It still should not be part of libvmcore, but is better than it was. Also teach it to be smart about hidden visibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76700 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert the addition of hasNoPointerOverflow to GEPOperator.Dan Gohman2009-07-201-5/+2
| | | | | | | | | | | | | Getelementptrs that are defined to wrap are virtually useless to optimization, and getelementptrs that are undefined on any kind of overflow are too restrictive -- it's difficult to ensure that all intermediate addresses are within bounds. I'm going to take a different approach. Remove a few optimizations that depended on this flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76437 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Edwin Török2009-07-141-5/+5
| | | | | | | | | | 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"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8

* Begin the painful process of tearing apart the rat'ss nest that is ↵Owen Anderson2009-07-131-104/+28
| | | | | | | | | | Constants.cpp and ConstantFold.cpp. This involves temporarily hard wiring some parts to use the global context. This isn't ideal, but it's the only way I could figure out to make this process vaguely incremental. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75445 91177308-0d34-0410-b5e6-96231b3b80d8

* assert(0) -> LLVM_UNREACHABLE.Edwin Török2009-07-111-4/+4
| | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert r73790, and replace it with a significantly less ugly solution. ↵Owen Anderson2009-06-201-316/+226
| | | | | | | | | | Rather than trying to make the global reader-writer lock work, create separate recursive mutexes for each value map. The recursive-ness fixes the double-acquiring issue, which having one per ValueMap lets us continue to maintain some concurrency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73801 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a serious bug that would cause deadlock during abstract type refinement. ↵Owen Anderson2009-06-191-221/+302
| | | | | | | | | | | The constant creation gets involved, and we end up trying to recursively acquire a writer lock. The fix for this is slightly horrible, and involves passing a boolean "locked" parameter around in Constants.cpp, but it's better than having locked and unlocked versions of most of the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73790 91177308-0d34-0410-b5e6-96231b3b80d8
