Subject: [PATCH v1 04/27] x86/fpu: Add file for common data used across svml_s_*_sse4.S files
Date: Wed, 7 Dec 2022 00:52:13 -0800 [thread overview]
Message-ID: <20221207085236.1424424-4-goldstein.w.n@gmail.com> (raw)
In-Reply-To: <20221207085236.1424424-1-goldstein.w.n@gmail.com>
All rodata that is used by more than one implementation can be defined
here to save .rodata size.
At the moment definitions are only for the following implementations:
atanf
atanhf
log
log10f
log2
tanf
have been added.
