Schorr <aschorr@telemetry-investments.com> + + Enhance API to support extended-precision arithmetic. + * awk.h (enum block_id): Add new values BLOCK_MPFR and BLOCK_MPZ. + (make_number_node): New inline function to reduce code duplication + for creating numeric nodes. + * gawkapi.h (gawk_api_major_version): Bump to 3. + (awk_number_t): New typedef to represent numbers with varying internal + representations. + (awk_value_t): For numbers, replace double with awk_number_t. + (num_value): Redefine. + (num_type, num_ptr): New defines for awk_number_t union members. + (gawk_api_t): Add constants for version checking: gmp_major_version, + gmp_minor_version, mpfr_major_version, and mpfr_minor_version. + Add functions api_get_mpfr and api_get_mpz to allocate memory for + extended-precision numbers to hand to gawk. + (get_mpfr_ptr, get_mpz_ptr): Helper macros to warp api_get_mpfr and + api_get_mpz. + (make_number): Modify to populate awk_number_t correctly. + (make_number_mpz, make_number_mpfr): New helper functions to create + extended-precision numeric nodes. + (check_mpfr_version): New macro to check GMP/MPFR version compatibility + in extensions that want to support extended-precision math. + * gawkapi.c (getmpfr, freempfr, getmpz, freempz): New macros to + allocate and free memory blocks for extended-precision math. + (awk_value_to_node): For AWK_NUMBER values, support 3 different kinds + of internal numbers: double, mpz_t, and mpfr_t. + (assign_number): New helper function to convert a numeric node to + an awk_value_t. + (node_to_awk_value): Use assign_number in a couple of places to + pass numbers properly. + (api_get_mpfr): Implement new api_get_mpfr hook. + (api_get_mpfz): Implement new api_get_mpz hook. + (api_impl): Add GMP & MPFR versions, api_get_mpfr, and api_get_mpz. + * node.c (r_make_number): Use new make_number_node inline function + to reduce code duplication. + (nextfree): Add block allocators for mpfr_t and mpz_t. + (more_blocks): Add an assert to protect against cases where the block + size is too small to hold our structure. + * mpfr.c (mpg_node): Use new make_number_node inline function + to reduce code duplication. + 2017-01-04 Arnold Robbins <arnold@skeeve.com> * config.guess, config.sub, compile, depcomp: Sync from latest |
