From: Richard Henderson <rth@twiddle.net> Basically moves op_t definition out to an specific header, adds the attribute 'may-alias', and cleanup its duplicated definitions. It lead to inclusion of tilegx32 gmp-mparam.h similar to x32 so op_t can be define as a long long (from _LONG_LONG_LIMB). Checked with a build and check with run-built-tests=no for all major Linux ABIs (alpha, aarch64, arm, hppa, i686, ia64, m68k, microblaze, mips, mips64, nios2, powerpc, powerpc64le, s390x, sh4, sparc64, tilegx, and x86_64).
