Hi, I'm trying to use the new debug info and I seem to have broken something. The attached LLVM assembly is the result of compiling a simple main() function. If I generate x86 assembly language from this I get the attached assembly file. The debug info seems complete, except that the .Lfunc_begin symbol is referenced but not defined in the .s file. llvm-dis, llvm-as, and llc seem

Hi Richard, How do you produce this LLVM assembly? In newest form, llvm.dbg.func_start intrinsic is not used. - Devang On Tue, Nov 3, 2009 at 5:48 AM, Richard Pennington <rich at pennware.com> wrote: > Hi, > > I'm trying to use the new debug info and I seem to have broken something. > The attached LLVM assembly is the result of compiling a simple main() > function.

...d stuff. However, even the asmprinter is taking a significant amount of time. This is partially because it has to output a ton of stuff, but even then it could be improved. For example, picking on the frontend for a bit, we spend 10% of "-emit- llvm -O0 -g -c" time in DebugInfo::EmitFunctionStart, most of which is spent recursively walking the debug info with DISerializer. We also spend 9.3% of the time in DebugInfo::EmitDeclare, 10% of the time in eraseLocalLLVMValues, 12% of the time writing the .bc file (which isn't relevant to normal use), 21% of time parsing (which we can&...
