From 63651705593278925c11634856c6a89702e4b791 Mon Sep 17 00:00:00 2001 From: Iain Sandoe Date: Sat, 11 Apr 2015 16:41:31 +0100 Subject: [PATCH] [llvm, Darwin, ppc] Darwin's default relocation model is PIC. I.E. not mdynamic-no-pic. Unfortunately, there is significant test-suite fallout from this. Some fixable by forcing the relocation model back to dynamic-no-pic. Some is not easily fixed this way and the intent of the test-cases is not 100% clear, so these have been XFAILed for now. These are old-style llc | grep and the target lines are not specific, so it's hard to know what to do. * mem_update.ll * tailcall1-64.ll * tailcall1.ll TODO: Verify tailcalls for Darwin (PIC and non-PIC) --- llvm/lib/Target/PowerPC/PPCTargetMachine.cpp | 3 +-- llvm/test/CodeGen/PowerPC/2007-02-23-lr-saved-twice.ll | 4 ++-- llvm/test/CodeGen/PowerPC/anon_aggr.ll | 7 ++----- llvm/test/CodeGen/PowerPC/hidden-vis-2.ll | 2 +- llvm/test/CodeGen/PowerPC/private.ll | 2 +- llvm/test/CodeGen/PowerPC/stubs.ll | 3 ++- llvm/test/CodeGen/PowerPC/tailcall1-64.ll | 1 + llvm/test/CodeGen/PowerPC/tailcall1.ll | 1 + llvm/test/CodeGen/PowerPC/vec_buildvector_loadstore.ll | 3 ++- 9 files changed, 13 insertions(+), 13 deletions(-) diff --git a/llvm/lib/Target/PowerPC/PPCTargetMachine.cpp b/llvm/lib/Target/PowerPC/PPCTargetMachine.cpp index 0c4733db451..facac947708 100644 --- a/llvm/lib/Target/PowerPC/PPCTargetMachine.cpp +++ b/llvm/lib/Target/PowerPC/PPCTargetMachine.cpp @@ -210,9 +210,8 @@ static Reloc::Model getEffectiveRelocModel(const Triple &TT, if (RM.hasValue()) return *RM;
