    I have have crafted assembly instructions and have made it faster than the same C code.

    Particular to if statements, C will do things push and pull values from the stack which takes a small but occasionally noticeable amount of cycles.

        Meanwhile I’m reverse engineering some very much not performance sensitive video game binary patcher program some guy made a decade ago and Ghidra interprets a string splitting function as a no-op because MSVC decided calling conventions are a spook and made up a new one at link time. And it was right to do that.

        EDIT: Also me looking for audio data from another old video game, patiently waiting for my program to take about half an hour on my laptop every time I run it. Then I remember to add --release to cargo run and while the compilation takes three seconds longer, the runtime shrinks to about ten seconds. I wonder if the above guy ever tried adding -O2 to his CFLAGS?

      python, what are you doing?"

      idk, I’m written in C, it does things push and pull values from the stack, have you tried assembly, it’s faster
