* add trivial support for passing label definitions through the MCStreamer.Chris Lattner2009-06-241-0/+7
| | | | | | | | This is suboptimal in several aspects, see the commented out assertion. I need to talk to Daniel about this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74057 91177308-0d34-0410-b5e6-96231b3b80d8
* Extend ScalarEvolution's multiple-exit support to compute exactDan Gohman2009-06-241-0/+6
| | | | | | | | | | | | | | | | trip counts in more cases. Generalize ScalarEvolution's isLoopGuardedByCond code to recognize And and Or conditions, splitting the code out into an isNecessaryCond helper function so that it can evaluate Ands and Ors recursively, and make SCEVExpander be much more aggressive about hoisting instructions out of loops. test/CodeGen/X86/pr3495.ll has an additional instruction now, but it appears to be due to an arbitrary register allocation difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74048 91177308-0d34-0410-b5e6-96231b3b80d8

* Make llvmc work again.Mikhail Glushenkov2009-06-233-0/+114
| | | | | | | | | | Chris recently broke llvmc with his Makefile changes (r75379). That patch made the global change .o -> .a, which caused built-in llvmc plugins to stop working since plugin initialization in llvmc is based on static variables not referenced from the main executable. This patch implements auto-generated forced references to the plugin libraries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74000 91177308-0d34-0410-b5e6-96231b3b80d8
