Hi, I am trying to add debugging information to a front-end. Following the example off llvm-gcc, I pretty much understood how MachineModuleInfo work but I have a question about the lifetime of the debug object. >From the implementation of DISerialiser, It seems to me I need to keep all my debug information object alive until the end of the compilation unit (until the

...is 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't help), Anyone interested in picking off a piece and tackling it? -Ch...
