commit 2c5e5ab6843d747c4b877d2c6f47226f61e9ff14
Author: Jussi Kivilinna <jussi.kivili...@iki.fi>
Date: Sun Jun 12 21:51:34 2022 +0300
ppc enable P10 assembly with ENABLE_FORCE_SOFT_HWFEATURES on arch 3.00
* cipher/chacha20.c (chacha20_do_setkey) [USE_PPC_VEC]: Enable
P10 assembly for HWF_PPC_ARCH_3_00 if ENABLE_FORCE_SOFT_HWFEATURES is
defined.
* cipher/poly1305.c (poly1305_init) [POLY1305_USE_PPC_VEC]: Likewise.
* cipher/rijndael.c (do_setkey) [USE_PPC_CRYPTO_WITH_PPC9LE]: Likewise.
---
This change allows testing P10 implementations with P9 and with QEMU-PPC.
