[PATCH v2] sparc: Remove optimize md5, sha256, and sha512
Adhemerval Zanella
adhemerval.zanella@linaro.org
Tue Aug 1 19:24:34 GMT 2023
The libcrypt was maked to phase out on 2.28, and better projects
already exist that provide both compatibility and better API
(libxcrypt). The sparc optimizations add the burden to extra
build-many-glibcs.py configurations.
Checked on sparc64 and sparcv9.
--
Changes from v1:
* Remove sparc --enable-crypt build-many-glibcs.py variant.
