Subject: [PATCH v2 0/6] aarch64: Added optimized memcpy/memmove/memset for A64FX
Date: Wed, 12 May 2021 09:23:08 +0000 [thread overview]
Message-ID: <20210512092308.900998-1-naohirot@fujitsu.com> (raw)
In-Reply-To: <20210317022849.323046-1-naohirot@fujitsu.com>
Hi Szabolcs, Wilco, Florian,
Thank you for reviewing Patch V1.
Patch V2 has been reflected all of V1 comments which are mainly
related to redundant assembler code.
Consequently assembler code has been minimized, and each line of V2
assembler code has been rationalized by string bench performance
data.
In terms of assembler LOC (lines of code), memcpy/memmove reduced 60%
from 1,000 to 400 lines, memset reduced 55% from 600 to 270 lines.
So please kindly review V2.
Thanks.
Naohiro
Naohiro Tamura (6):
config: Added HAVE_AARCH64_SVE_ASM for aarch64
aarch64: define BTI_C and BTI_J macros as NOP unless HAVE_AARCH64_BTI
aarch64: Added optimized memcpy and memmove for A64FX
aarch64: Added optimized memset for A64FX
scripts: Added Vector Length Set test helper script
benchtests: Fixed bench-memcpy-random: buf1: mprotect failed
