Re: [EE] Saving "printf" arguments for later? Real-time on slow processor.

I've got roughly 10000 printf calls that would need swapped out (it's a big
library). And the library is updated frequently,

I would need to write a program to scan through the source, and change each
printf. (and really, with so many changes, I'd like to be able to undo the
changes so that I can run a "diff")

While I had hoped I could avoid parsing the string, I feel writing a
"function call transformer program" is too much work for only a small
speedup.


If you have any leads on ways to make that function swapping easier, I'm
open to it. But I think if I went through with it I would end up writing a
custom Rust program that parses all the source files in each directory,
determines the type signature, and does the swap. (comments out the old
function with a unique marker, and then places the new function with same
arguments surrounded by comment markers)
