2021-08-03[llvm-readobj][XCOFF] Fix the error dumping for the firstEsme-Yi1-1/+4
item of StringTable. Summary: For the string table in XCOFF, the first 4 bytes contains the length of the string table, so we should print the string entries from fifth bytes. This patch also adds tests for llvm-readobj dumping the string table. Reviewed By: jhenderson Differential Revision: https://reviews.llvm.org/D105522

getRelocatedSection interface should not check that the object file is relocatable, as executable files may have relocations preserved with `--emit-relocs` linker flag. The relocations are useful in context of post-link binary analysis for function reference identification. For example, BOLT relies on relocations to perform function reordering.

traceback table of the xcoff. SUMMARY: 1. decode the Vector extension if has_vec is set 2. decode long table fields, if longtbtable is set. There is conflict on the bit order of HasVectorInfoMask and HasExtensionTableMask between AIX os header and IBM aix compiler XLC. In the /usr/include/sys/debug.h defines static constexpr uint32_t HasVectorInfoMask = 0x0040'0000; static constexpr uint32_t HasExtensionTableMask = 0x0080'0000; but the XLC defines as static constexpr uint32_t HasVectorInfoMask = 0x0080'0000; static constexpr uint32_t HasExtensionTableMask = 0x0040'0000; we follows the definition of the IBM AIX compiler XLC here.

2020-04-06[llvm-objdump][XCOFF] Use symbol index+symbol name + storage mapping class ↵diggerlin1-0/+4
as label for -D SUMMARY: For the llvm-objdump -D, the symbol name is used as a label in the disassembly for the specific address (when a symbol address is equal to the virtual address in the dump). In XCOFF, multiple symbols may have the same name, being differentiated by their storage mapping class. It is helpful to print the QualName and not just the name when forming the output label for a csect symbol. The symbol index further removes any ambiguity caused by duplicate names. To maintain compatibility with the binutils objdump, the XCOFF-specific --symbol-description option is added to enable the enhanced format.

This reverts commit c989993ba1a666f04f7aee7df51d9f4de0588b71. maskray already fixed the explicit instantiation definition in the .cpp file, and these extern template declarations seem to be causing warnings that I don't understand.
2019-11-07[XCOFF] Fix link errors from explicit template instantiationReid Kleckner1-0/+4
I happen to be using clang-cl+lld-link locally, and I get these link errors: lld-link: error: undefined symbol: public: unsigned short __cdecl llvm::object::XCOFFSectionHeader<struct llvm::object::XCOFFSectionHeader64>::getSectionType(void) const >>> referenced by C:\src\llvm-project\llvm\tools\llvm-readobj\XCOFFDumper.cpp:106 >>> tools\llvm-readobj\CMakeFiles\llvm-readobj.dir\XCOFFDumper.cpp.obj:(public: virtual void __cdecl `anonymous namespace'::XCOFFDumper::printSectionHeaders(void)) I suspect this is because the explicit template instaniation appears before the inline method definitions in the .cpp file, so they aren't available at the point of instantiation. Move the explicit instantiation later. Also, forward declare the explicit instantiation for good measure.
