Please review the enclosed patch for Sparc debug info. I have been able to view source files, set breakpoints, and single step source lines after applying this patch.

...sBlockOnlyReachableByFallthrough. Then you can make it virtual, and have the sparc backend provide its own implementation of it (which might as well just return false all the time). Sounds reasonable to me. The attached llvm-sparc-asmprinter1.patch implements what you've described above, with SparcAsmPrinter::isBlockOnlyReachableByFallthrough looking for the last terminator rather than the last instruction. I've also included llvm-sparc-asmprinter2.patch which fixes a different issue in SparcAsmPrinter where multiple identical .LLGETPCHn symbols could be emitted in the same file (it was uniqued...

I see that JIT isn't supported for the Sparc targets for example. What is the scope of the change to add JIT support. I see, for example, that for X86 target class X86JITInfo is defined with 10 methods. It's only used in one place: setPICBase. Also createX86JITCodeEmitterPass creates JIT pass -- very simple. So is implementing these steps enough to add JIT, or there are some hidden
