I have a branch lying around which does some de-inlining in sprintf. It reduces code size by half. There was no real speed advantage, but I only ran some micro benchmarks on i7, so I assume there was no cache pressure.
I pushed those sprintf de-inlining changes into a new branch 'arne/slim'. That patch alone makes sprintf about 75% smaller. During my yesterday train ride I wrote another patch that changes the generation of sscanf functions. Instead of having one funciton for each strings width of both the format and the input, it uses the PCHARP accessor functions for the format. I have not run any benchmarks to see how much slower it is, but it saves about 60% of code size there. arne
