From a1db5de9e70dd8ffda57b1a4373915ea866b6f1d Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 9 Jan 2013 17:08:15 +0000 Subject: PowerPC: EH adjustments This patch adjust the r171506 to make all DWARF enconding pc-relative for PPC64. It also adds the R_PPC64_REL32 relocation handling in MCJIT (since the eh_frame will not generate PIC-relative relocation) and also adds the emission of stubs created by the TTypeEncoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171979 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'lib/ExecutionEngine/RuntimeDyld') diff --git a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp index 0a68f4e..1524b48 100644 --- a/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp +++ b/lib/ExecutionEngine/RuntimeDyld/RuntimeDyldELF.cpp @@ -523,7 +523,7 @@ void RuntimeDyldELF::resolvePPC64Relocation(const SectionEntry &Section, case ELF::R_PPC64_ADDR32 : { int32_t Result = static_cast(Value + Addend); if (SignExtend32<32>(Result) != Result) - llvm_unreachable("Relocation R_PPC64_REL32 overflow"); + llvm_unreachable("Relocation R_PPC64_ADDR32 overflow"); writeInt32BE(LocalAddress, Result); } break; case ELF::R_PPC64_REL24 : { @@ -534,6 +534,13 @@ void RuntimeDyldELF::resolvePPC64Relocation(const SectionEntry &Section, // Generates a 'bl
