Let me also add that the gmp.h file does not define mpn_andn_n symbol at all neither it declare __gmpn_andn_n function! Since both i386 and sparc gmp.h are the same this applies to both.
Oh, I just checked the documentation, and `mpn_andn_n()` is only mentioned in the GMP 5.0.x docs https://gmplib.org/manual-5.0.4/Low_002dlevel-Functions.html#Low_002dlevel-F... but not in https://gmplib.org/manual-4.3.2/Low_002dlevel-Functions.html#Low_002dlevel-F... [...]
The big issue here is that i386/solaris gmp library so file provides this __gmpn_andn_n symbol but have not declared it in gmp.h at all in a form of mpn_andn_n define. So basically your: -- void mpn_andn_n (mp_limb_t *rp, const mp_limb_t *s1p, const mp_limb_t *s2p, -- mp_size_t n) foreign import ccall unsafe "gmp.h __gmpn_andn_n" c_mpn_andn_n :: MutableByteArray# s -> ByteArray# -> ByteArray# -> GmpSize# -> IO ()
works on i386, but not on sparc.
Is it possible for you to test for those mpn_ symbols in integrer-gmp2 configure and if they are presented then you can use your __gmpn_andn_n foreigner call?
I'm actually rather considering not using those at all when GMP version is 4.* as they're not part of the official API of GMP 4.x Btw, how long do we need to keep supporting GMP 4.x (as it lacks a few other features)? GMP 5.0.0 has been released over 5 years ago... :-/ Cheers, hvr
