2014-09-22 Niels Möller <nisse@lysator.liu.se>
+ * ecc-internal.h (ecc_mod_inv_func): New typedef.
+ (struct ecc_modulo): Added mp1h constant and invert function
+ pointer. Updated all callers.
+ * ecc-modp.c (ecc_modp_inv): Deleted wrapper function.
+ * ecc-modq.c (ecc_modq_inv): Deleted wrapper function.
+
+ * ecc-mod-inv.c (ecc_mod_inv): Renamed file and function. Also
+ take a struct ecc_modulo * as argument.
+ * sec-modinv.c (sec_modinv): ... the old names. Deleted.
+ * Makefile.in (hogweed_SOURCES): Updated accordingly.
+
* examples/ecc-benchmark.c (bench_modinv_powm, bench_curve):
Updated benchmarking of mpn_sec_powm.
