Hi,
We are porting musl to our dsp architecture.
Since there are a quite a few functions we do not implement, we would like to generate a compatibility table like the ones listed at http://wiki.musl-libc.org/wiki/Compatibility for posix, c99 and c11.
Is there a script or test suite (libc-test?) to generate the tables?
Thanks,
-Philippe

I think they're generated from the code in this repo:

these are messy shell+awk scripts
(never intended for others to look at it)
basic idea:
- data dir has c99, c11 and posix2008 api list
(tab separated values, c api is from annex b of the iso pdf,
posix api is from the downloadable html)
- defined symbols in libc.a are listed with nm
- declared symbols in headers are listed with ctags
(this is not perfect, will parse all ifdef branches etc
and i try to check the prototypes too which is hard)
- musl syms are compared to the api lists
furthermore libc-test has an api test which does check
function prototypes properly for all posix functions
(but there is no nice report about it)
and i have some scripts to test posix namespace violations
using ctags data and the posix namespace rules which i
collected here:
http://port70.net/~nsz/c/posix/
hope this helps
