From 68c9641855199f34aabe1050e863c21830116fe1 Mon Sep 17 00:00:00 2001 From: Serhey Popovych Date: Fri, 14 Dec 2018 19:54:34 +0200 Subject: arch-powerpc64.inc: Use elfv2 ABI when building with musl Historically first PowerPC ABI was big-endian only (elfv1 currently). It is standard ABI for both 32-bit ppc and 64-bit ppc64 architectures. With PowerPC little-endian support new ABI was introduced (elfv2) and it is used primarily with ppc64le target only. While it has support for big-endian it is not commonly used and elfv1 still preferred. Musl does support only elfv2 ABI for both LE and BE and does not have any plans to support elfv1. Since then to build for powerpc64 with musl new ABI should be used. As expected it is not compatible with elfv1 but that isn't problem as long as there is no binary distributed software or assembly code written for elfv1 ABI.
