Subject: [PATCH 0/7] Remove _STRING_ARCH_unaligned
Date: Mon, 13 Feb 2023 10:55:51 -0300 [thread overview]
Message-ID: <20230213135558.3328727-1-adhemerval.zanella@linaro.org> (raw)
The _STRING_ARCH_unaligned advertise that the architecture allows
efficient unaligned memory accesses and it is used to optimize some
implementations.
However, some are complete unnecessary and only adds complexity
(getenv), while other can be removed since they add only marginal
improvement on legacy/compat code (crypt and nscd).
The iconv code can be also simplified by using compiler extension
(packaed struct) that allows code efficient code generation without
the need to provide aligned/unaligned variants.
