Subject: [PATCH 16/25] sparc: refactor sparc64 __mpn_submul_1 selector to C
Date: Thu, 26 Oct 2017 19:07:00 -0000 [thread overview]
Message-ID: <1509044813-9951-17-git-send-email-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <1509044813-9951-1-git-send-email-adhemerval.zanella@linaro.org>
This patch refactors the sparc64 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
submul_1-generic.S).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
Add submul_1-generic.
* sysdeps/sparc/sparc64/multiarch/submul_1-generic.S: New file.
* sysdeps/sparc/sparc64/multiarch/submul_1.c: Likewise.
* sysdeps/sparc/sparc64/multiarch/submul_1.S: Remove file.
