Subject: gmp's c++ interface / mpz_class
Date: Fri, 14 Oct 2022 19:11:39 +0100 [thread overview]
Message-ID: <e2ccd323-a876-cd0d-4ae5-6c26a78f6224@palves.net> (raw)
Hi!
Zoran and I found a potential need for an integer type with precision of 64-bit + 8-bit, in order to
store bit offsets that can span a whole 64-bits address space. Instead of rolling our own,
I guess it makes sense to use libgmp, since, well, we already depend on it. I see that we have:
/* A class to make it easier to use GMP's mpz_t values within GDB. */
struct gdb_mpz
{
In gdb/gmp-utils.h. However, we need do to arithmetic on the type, and this wrapper
type doesn't implement operator+, operator-, etc, etc. I guess we could add those,
as wrappers around mpz_add, etc. Or use raw mpz_add, etc. directly. However, I just found
out that GMP already has its own C++ interface:
https://gmplib.org/manual/C_002b_002b-Interface-General
Before we explore this further, is there an already known reason we shouldn't be using
that interface?
