SnoopCompile has a feature of timing the time spent in LLVM to optimize Julia code. This is a talk sharing my experiences using the macro snoopl to debug the time spent optimizing each function in LLVM.
In this talk, I would present my current workflow for debugging the time spent in LLVM optimizing functions and share my experience of using SnoopCompile to understand where are the problems of a large code base to perform faster Time To First X (TTFX).
