2011-08-30Remove the old tail duplication pass. It is not used and is unable to updateRafael Espindola
ssa, so it has to be run really early in the pipeline. Any replacement should probably use the SSAUpdater. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138841 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-23Replace calls to ConstantFoldInstruction with calls to SimplifyInstructionDuncan Sands

2010-10-19Get rid of static constructors for pass registration. Instead, every pass ↵Owen Anderson
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116820 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25More migration to raw_ostream, the water has dried up around the iostream hole.Daniel Dunbar
- 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

2009-07-17Replace isTrapping with a new, similar method called Eli Friedman
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
