From: Vincent Fazio Date: Tue, 4 Feb 2020 21:35:48 +0000 (-0600) Subject: toolchain/toolchain-buildroot: PPC64(LE) support in musl requires ALTIVEC X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=20c267f2e9a9664a87a1804555dd4703e9a3665c;p=buildroot.git toolchain/toolchain-buildroot: PPC64(LE) support in musl requires ALTIVEC musl currently assumes all PPC64(LE) CPUs support ALTIVEC instructions. However, there are exceptions (such as the e5500) for which musl builds ultimately generate illegal instructions for the targets. Disable musl if the PPC64(LE) CPU does not support ALTIVEC instructions. This patch addresses the issues seen here: https://gitlab.com/kubu93/toolchains-builder/-/jobs/418092743 https://gitlab.com/kubu93/toolchains-builder/-/jobs/418092744 musl mailing list thread: https://www.openwall.com/lists/musl/2020/02/03/10 Signed-off-by: Vincent Fazio Reviewed-by: Romain Naour Signed-off-by: Yann E.
