Simplify ecc-benchmark.c and delete curve25519 special case.

parent 0a8fb3bb
2019-12-17 Niels Möller <nisse@lysator.liu.se>
* examples/ecc-benchmark.c (bench_dup_hh): Rename, and use
ecc->dup pointer.
(bench_dup_jj): ... old name.
(bench_add_hh): Rename, and use ecc->addd_hh pointer.
(bench_add_jja): ... old name.
(bench_dup_eh, bench_add_eh): Deleted.
(bench_curve): Update, and delete curve25519 special case.
(main): Update table headers accordingly.
2019-12-15 Niels Möller <nisse@lysator.liu.se>
* ecc-dup-eh.c (ecc_dup_eh): Eliminate one unneeded ecc_modp_add.
