00:12 <Wily--> has anyone been playing with openocd on SPI on RPi?

11:17 <erhankur> Hi Antonio, which script did you run to catch un-exported local symbols?

11:18 <PaulFertser> Needlessly exported symbols

11:18 <PaulFertser> I know you can build with -ffunction-sections and then link with --gc-sections and in the map file it'll list all the sections it threw out.

11:19 <PaulFertser> Guess borneoa_ used something less time consuming than that though.

11:20 <borneoa_> Hi

11:21 <borneoa_> I compile openocd then run 'nm' on all the files .o to get the symbols, then a one line script to find symbols exported and not referenced

11:22 <borneoa_> I can post the script later today

11:23 <erhankur> Thanks @PaulFertser @borneoa_

11:25 <PaulFertser> "my method" would miss functions that didn't get inlined so consider that an unrelated idea, not the real answer.

11:29 <borneoa_> I tried to integrate the nm stuff on the makefile, something like 'make unused_symbols', but our build system is per sub-library, and I don't have the way to run the final script. I will try again but it's more complicated than I thought

11:52 <erhankur> Maybe such kind of scripts can be integrated to Jenkins stage.

12:30 <borneoa_> There are symbols exported to complete the API, like something_read() with something_write() but only one is used out of the file that defines it. I'm not going to drop the one not used.

12:31 <borneoa_> I have posted the script in a comment of 7167, with one improvement I have not used yet
