We are using ppc32 in our products for ages. This is simply the first
time we need libgcrypt.
I saw that the code has not been changed for ages. But if you have a
look at syntax.h, it is pretty obvious that it cannot work this way.
EALIGN adds another underscore while END does not.
But they are called (e.g. inmpih-add1.S) with
EALIGN(_gcry_mpih_add_n,3,0) and END(_gcry_mpih_add_n).
Both start the parameter with an underscore.
After passing the preprocessor this results in:
.globl __gcry_mpih_add_n; .type __gcry_mpih_add_n, at function; .align 3;
This leads to
Error: .size expression for _gcry_mpih_add_n does not evaluate to a constant
