Subject: [PATCH v8 00/17] Improve generic string routines
Date: Fri, 13 Jan 2023 08:27:16 -1000 [thread overview]
Message-ID: <20230113182733.1268668-1-richard.henderson@linaro.org> (raw)
Changes since v7:
- Split string-fzc.h out of string-fzi.h, with all of the
routines that are combinations of fza and fzi routines.
- Fix missing find_t and shift_find() from alpha, arm, powerpc.
- Use compiler builtins for arm and powerpc.
- Define sh4 has_zero() via has_eq(), rather than reverse.
