I want to see the C code which GMP uses for multiplication when I use
mpz_mul () function and compile my C code using -lgmp flag.
Is it the code in the folder gmp-6.1.2\mpn\generic\mul_n.c ?
Or is it some other multiplication code in any other folder?
Can someone help me understand which code gets executed ?
Which code is executed depends on which function you call. Typically,
mpn/generic/mul.c will get called quite soon in all cases.
Following GMP call chains can be tricky, just like with any other
program. I usually use "grep -r function-name" to find call sites and
definition of a function.
An alternative is to use a debugger and single step through an example
Unfortunately, help at this level is a bit outside of what the GMP
volunteers can offer.
