GMP library function body implementations

I've been running the GMP 5.0.2 'make check' and encountered some fails
because of my CPU errors. (FYI, the GMP library has been built natively on
I debug one of these tests (tests/mpz/convert.c). The GMP library is built
with the debug flag (-g) so I hoped to be able to debug the inside of GMP
library functions. However, I fail to do it.
The reason is that the function implementations (e.g. mpz_get_str) is
replaced in code with another function (__gmpz_get_str). Of course, one can
see the define '#define mpz_get_str __gmpz_get_str' in gmp.h header. But
where is the source that becomes the '__gmpz_get_str' code? I couldn't have
found it. The process of GMP library compiling is not quite clear for me.
I tried to change the implementation of 'mpz_get_str' in 'dumbmp.c', but it
had only affected the process of GMP build. After the library was built,
the implementation of 'mpz_get_str' (really '__gmpz_get_str') had remained
Is there a way to find the modifiable code for these functions
('mpz_get_str', as well as 'mpz_set_str_or_abort', 'mpz_cmp' etc.) in order
to modify the source, rebuild and debug it to find my error?
Thanks in advance,
