From 750d323a6060ad92c3d247f85d6555041f55b4a5 Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Thu, 4 Oct 2018 15:26:59 -0500 Subject: [PATCH] Add support for powerpc64-*-linux-musl targets This patch ensures that 64-bit PowerPC musl targets use ELFv2 ABI on both endians. It additionally adds a test that big endian PPC64 uses ELFv2 on musl. --- lib/Target/PowerPC/PPCTargetMachine.cpp | 4 ++++ test/CodeGen/PowerPC/ppc64-elf-abi.ll | 1 + 2 files changed, 5 insertions(+) diff --git a/lib/Target/PowerPC/PPCTargetMachine.cpp b/lib/Target/PowerPC/PPCTargetMachine.cpp index 34410393ef6..c583fba8cab 100644 --- a/lib/Target/PowerPC/PPCTargetMachine.cpp +++ b/lib/Target/PowerPC/PPCTargetMachine.cpp @@ -199,6 +199,10 @@ static PPCTargetMachine::PPCABI computeTargetABI(const Triple &TT, case Triple::ppc64le: return PPCTargetMachine::PPC_ABI_ELFv2; case Triple::ppc64: + // musl uses ELFv2 ABI on both endians. + if (TT.getEnvironment() == Triple::Musl) + return PPCTargetMachine::PPC_ABI_ELFv2; + return PPCTargetMachine::PPC_ABI_ELFv1; default: return PPCTargetMachine::PPC_ABI_UNKNOWN;
