...rmance numbers of the old C code vs. the asm goto: https://lwn.net/Articles/350714/ This LTTng (Linux Trace Toolkit Next Generation) presentation talks about using this feature as a way of optimize static tracepoints (slides 3-4) https://www.computer.org/cms/ComputingNow/HomePage/2011/0111/rW_SW_UsingTracing.pdf This presentation also mentions that a lot of other Linux applications use this tracing mechanism. I believe we already have much of the infrastructure in place (using the indirecbr instruction infrastructure). We do need to make sure MachineBlockPlacement optimizes the fall through path t...
