MPROF_MERGE_RUNS(1)

okay bestie, welcome to MPROF_MERGE_RUNS(1), from the General Commands Manual 💅 This is the Mercury profiling utility page, and it's lowkey iconic. ✨

🎀 NAME 🎀

mprof_merge_runs — the Mercury profiling utility. That's the vibe, periodt. 💖

🦋 DESCRIPTION 🦋

mprof_merge_runs merges the profiling data from different runs of a profiled Mercury program, for use by mprof. no cap — it's the merge bestie that pulls your separate run eras together so the profile can actually slay. ✨

🌸 USAGE 🌸

First, compile with profiling enabled, bestie:

mmc --profiling my_program

Then, collect the profiling data:

./my_program  args for first run
mprof_merge_runs
./my_program  args for second run
mprof_merge_runs
./my_program  args for third run
mprof_merge_runs

Finally, display the profile:

mprof -c | more

Note: if you just want to run your program N times with the same arguments, a simpler way of achieving this is to instead use the -r<N> ("repeat N times") option to the Mercury runtime, which you can pass by setting the environment variable MERCURY_OPTIONS, e.g.

env MERCURY_OPTIONS=-r100 ./my_program

🧚 NOTES 🧚

mprof_merge_runs is one of the development tools that are part of the Mercury distribution. 💜
