From 1c61471ab1cba735f57824ec8a38db845e60ab84 Mon Sep 17 00:00:00 2001 From: Fangrui Song Date: Wed, 22 May 2019 07:29:59 +0000 Subject: [PPC64] Parse -elfv1 -elfv2 when specified on target triple MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Summary: For big-endian powerpc64, the default ABI is ELFv1. OpenPower ABI ELFv2 is supported when -mabi=elfv2 is specified. FreeBSD support for PowerPC64 ELFv2 ABI with LLVM is in progress[1]. This patch adds an alternative way to specify ELFv2 ABI on target triple [2]. The following results are expected: ELFv1 when using: -target powerpc64-unknown-freebsd12.0 -target powerpc64-unknown-freebsd12.0 -mabi=elfv1 -target powerpc64-unknown-freebsd12.0-elfv1 ELFv2 when using: -target powerpc64-unknown-freebsd12.0 -mabi=elfv2 -target powerpc64-unknown-freebsd12.0-elfv2 [1] https://wiki.freebsd.org/powerpc/llvm-elfv2 [2] https://clang.llvm.org/docs/CrossCompilation.html Patch by Alfredo Dal'Ava Júnior!
