Subject: [PATCH v1 1/8] x86: Create header for VEC classes in x86 strings library
Date: Thu, 2 Jun 2022 23:42:22 -0500 [thread overview]
Message-ID: <20220603044229.2180216-1-goldstein.w.n@gmail.com> (raw)
This patch does not touch any existing code and is only meant to be a
tool for future patches so that simple source files can more easily be
maintained to target multiple VEC classes.
There is no difference in the objdump of libc.so before and after this
patch.
