* now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate theChris Lattner2010-11-171-1/+2
| | | | | | | | | cookie argument to the SourceMgr diagnostic stuff. This cleanly separates LLVMContext's inlineasm handler from the sourcemgr error handling definition, increasing type safety and cleaning things up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119486 91177308-0d34-0410-b5e6-96231b3b80d8

* give LLVMContext an inline asm diagnostic hook member.Chris Lattner2010-04-061-0/+2
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100506 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a new "NewDebugLoc" class which will eventually replace DebugLoc,Chris Lattner2010-04-011-1/+44
| | | | | | | | | | | | | | and will replace the 'DbgInfo' member in Instruction. The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24 bytes for the DbgInfo member in Instruction on a 32/64 bit system), it means that we will end up not having to allocate MDNodes to represent the "DILocations" in common cases of -O0 -g, and it is much more efficient to get things out of than the MDNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100072 91177308-0d34-0410-b5e6-96231b3b80d8

* Free the constants that have no uses in ~LLVMContext.Torok Edwin2009-08-311-1/+22
| | | | | | | | | | | | This fixes leaks from LLVMContext in multithreaded apps. Since constants are only deleted if they have no uses, it is safe to not delete a Module on shutdown, as many single-threaded tools do. Multithreaded apps should however delete the Module before destroying the Context to ensure that there are no leaks (assuming they use a different context for each thread). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80590 91177308-0d34-0410-b5e6-96231b3b80d8
