looks on lib/msun
generic one are in src.
Specific ones are the other directories
amd64 bsdsrc ld128 mips sparc64
arm i387 ld80 powerpc x86
On FreeBSD I have not yet fond a missing one, but I have not checked
all expected by POSIX.
NetBSD miss almost all the functions. Only
the rounding functions are implemented. For all the others
it is just
#define coshl _coshl
#define sinhl _sinhl
#define acosl _acosl
#define atanl _atanl

then I will just leave
as found in FreeBSD
ls -1 src/*fabs*c
