From 3e96531186ba574b0c25a4be62d24b8b7d752c9f Mon Sep 17 00:00:00 2001 From: Jim Grosbach Date: Fri, 18 May 2012 19:12:01 +0000 Subject: Refactor data-in-code annotations. Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Object/MachOObject.cpp | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'lib/Object') diff --git a/lib/Object/MachOObject.cpp b/lib/Object/MachOObject.cpp index b7e5cdcd6b..00dea3fe47 100644 --- a/lib/Object/MachOObject.cpp +++ b/lib/Object/MachOObject.cpp @@ -357,6 +357,19 @@ void MachOObject::ReadSymbol64TableEntry(uint64_t SymbolTableOffset, ReadInMemoryStruct(*this, Buffer->getBuffer(), Offset, Res); } +template<> +void SwapStruct(macho::DataInCodeTableEntry &Value) { + SwapValue(Value.Offset); + SwapValue(Value.Length); + SwapValue(Value.Kind); +} +void MachOObject::ReadDataInCodeTableEntry(uint64_t TableOffset, + unsigned Index, + InMemoryStruct &Res) const { + uint64_t Offset = (TableOffset + + Index * sizeof(macho::DataInCodeTableEntry)); + ReadInMemoryStruct(*this, Buffer->getBuffer(), Offset, Res); +} void MachOObject::ReadULEB128s(uint64_t Index, SmallVectorImpl &Out) const { -- cgit v1.2.3
