Subject: [PATCH v6 1/7] x86: Update and move evex256/512 vec macros
Date: Fri, 14 Oct 2022 17:39:08 -0500 [thread overview]
Message-ID: <20221014223914.700492-1-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20221014164008.1325863-1-goldstein.w.n@gmail.com>
1) Copy so that backport will be easier.
2) Make section only define if there is not a previous definition
3) Add `VEC_lo` definition for proper reg-width but in the
ymm/zmm0-15 range.
This commit does not change libc.so
Tested build on x86-64
