* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-2517-83/+107
| | | | | | | | | | | - Some clients which used DOUT have moved to DEBUG. We are deprecating the "magic" DOUT behavior which avoided calling printing functions when the statement was disabled. In addition to being unnecessary magic, it had the downside of leaving code in -Asserts builds, and of hiding potentially unnecessary computations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77019 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | - Yay for '-'s and simplifications! - I kept StringMap::GetOrCreateValue for compatibility purposes, this can eventually go away.

* Revert the addition of hasNoPointerOverflow to GEPOperator.Dan Gohman2009-07-201-84/+1
| | | | | | | | | | | | | 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
