2022-10-14arc: add optimized string functions for ARCv3Pavel Kozlov
Add ability to use optimized versions of string functions for ARCv3 32-bit CPUs with UCLIBC_HAS_STRING_ARCH_OPT option. Add optimized memcpy/memset/memcmp code for ARCv3 CPUs based on the code from newlib and adapt for ARCv3 existed optimized strchr/strcmp/strcpy/strlen. Link to the Synopsys newlib repo with code for ARCv3 on GitHub: https://github.com/foss-for-synopsys-dwc-arc-processors/newlib Signed-off-by: Pavel Kozlov <pavel.kozlov@synopsys.com>
2017-08-20arc: Merge ARCv2 string routines in generic ARC .S filesAlexey Brodkin
In cde74b83f9b2 "ARC: remove special CFLAGS/LDFLAGS handling" we got rid of CONFIG_ARC_CPU_HS which was used to select ARCv2-specific implementation of optimized string routines. So now ARCv2-tuned memset/memcpy/strcmp are not used, instead those for ARC700 used for both ARC700 and ARCHS. Without uClibc config option we may only tell which CPU type we're targeting by built-in defines of GCC. I.e. no more conditional file inclusion in Makefiles. That leaves us only one option - merge both implementations in 1 file and use ifdefs. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
