* Separate result area for ecc_mod_mul and ecc_mod_sqr.Niels Möller2020-11-0127-224/+214
| | | | | | | | * ecc-mod-arith.c (ecc_mod_mul, ecc_mod_sqr): Separate argument for scratch area, reducing required size of result area. Update all callers to naïvely keep using result in scratch area. (ecc_mod_pow_2k, ecc_mod_pow_2k_mul): Simplified, also reducing required size of result area.
* testsuite: Show curve bits in test_ecc_point failure message.Niels Möller2020-11-012-2/+6

|
* Add separate result argument to all mod functions.Niels Möller2020-10-3022-162/+215
| | | | | * ecc-internal.h (typedef ecc_mod_func): Add separate result argument. Updated all C implementations and callers.
* Delete testcase, it's invalid with 32-bit limbs.Niels Möller2020-10-302-5/+0
|
* Simplify ecc_mod, and prepare for separate result argument.Niels Möller2020-10-293-20/+20
| | | | | | * ecc-mod.c (ecc_mod): More unified handling of final carry folding. Also eliminates a goto statement. * testsuite/ecc-mod-test.c (test_fixed): Add another test case
* blowfish: Add casts to uint32_t.Niels Möller2020-10-292-2/+10
| | | | | Avoids undefined behavior, since shifting an 8-bit value left by 24 bits overflows the range of signed int. Reported by Guido Vranken.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * ecc-mod-inv.c (ecc_mod_inv_destructive): New helper function, not preserving input argument. Extracted from old ecc_mod_inv. (ecc_mod_inv): Call ecc_mod_inv_destructive. (ecc_mod_inv_redc): New inversion function, with input and output in redc form. * ecc-secp224r1.c: Select between ecc_mod_inv and ecc_mod_inv_redc. * ecc-secp256r1.c: Likewise. * ecc-j-to-a.c (ecc_j_to_a): Simplify redc-related logic, taking advantage of ecc->p.invert handling redc, when appropriate. Reduce scratch need from 5n to 4n in the process (assuming inversion needs 2n). * testsuite/ecc-modinv-test.c (ref_modinv): Updated to do redc, if appropriate.

* | "PowerPC64" Use explicit register namesMaamoun TK2020-09-233-197/+200
| | | | | | | | | | This patch is built upon ppc-m4-macrology.patch. Using explicit register names is working as expected now.
* | ppc: Add configure test and macros to replace register names.Niels Möller2020-09-216-2/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | * aclocal.m4 (GMP_ASM_POWERPC_R_REGISTERS): New configure test, adapted from corresponding test in GMP's acinlude.m4. * configure.ac (ASM_PPC_WANT_R_REGISTERS): New substituted variable. Set using GMP_ASM_POWERPC_R_REGISTERS, when powerpc64 assembly code is enabled. * config.m4.in: Substituted here. * powerpc64/machine.m4: Check ASM_PPC_WANT_R_REGISTERS, and if needed, replace register names like r0, r1, ... with integers. * Makefile.in (%.asm): Include m4-utils.m4 for preprocessing of .asm files, and include config.m4 before machine.m4.
* | M4 utilities, from GMP.Niels Möller2020-09-213-1/+443
| | | | | | | | | | | | * m4-utils.m4: New file with m4 utilities, copied from GMP's mpn/asm-defs.m4. * Makefile.in (DISTFILES): Add m4-utils.m4.
