* More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar2009-07-252-6/+8
| | | | | | | | | | | - 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

* Replace isTrapping with a new, similar method called Eli Friedman2009-07-171-17/+6
| | | | | | | | | | | | isSafeToSpeculativelyExecute. The new method is a bit closer to what the callers actually care about in that it rejects more things callers don't want. It also adds more precise handling for integer division, and unifies code for analyzing the legality of a speculative load. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76150 91177308-0d34-0410-b5e6-96231b3b80d8

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

| | | | | | | | | | 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

* Remove the block from the LoopInfo, rather than just the Loop.Dan Gohman2009-06-271-1/+1

* Teach LoopSimplify how to merge multiple loop exits into a single exit,Dan Gohman2009-06-272-1/+76
| | | | | | | | | | | | | | | | | when one of them can be converted to a trivial icmp and conditional branch. This addresses what is essentially a phase ordering problem. SimplifyCFG knows how to do this transformation, but it doesn't do so if the primary block has any instructions in it other than an icmp and a branch. In the given testcase, the block contains other instructions, however they are loop-invariant and can be hoisted. SimplifyCFG doesn't have LoopInfo though, so it can't hoist them. And, it's important that the blocks be merged before LoopRotation, as it doesn't support multiple-exit loops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74396 91177308-0d34-0410-b5e6-96231b3b80d8
