2020-01-30[XCOFF][AIX] Support basic relocation type on AIXjasonliu1-0/+1
Summary: This patch intends to support three most common relocation type on AIX: R_POS, R_TOC, R_RBR. These three relocation type will be needed for object file generation on AIX for small code model. We will have follow up patches to bring relocation support for large code model on AIX.

2019-11-19The patch is the compiler error specific on the compile error on CMVCdiggerlin1-3/+5
SUMMARY: CMVC has a compiler error on the const uint64_t OffsetToRaw = is64Bit() ? toSection64(Sec)->FileOffsetToRawData : toSection32(Sec)->FileOffsetToRawData; while gcc compiler do not have the problem. I have to change the code to uint64_t OffsetToRaw; if (is64Bit()) OffsetToRaw = toSection64(Sec)->FileOffsetToRawData; else OffsetToRaw = toSection32(Sec)->FileOffsetToRawData; Reviewers: Sean Fertile Subscribers: rupprecht, seiyai,hiraditya Differential Revision: https://reviews.llvm.org/D70255

2019-11-07Revert "[XCOFF] Fix link errors from explicit template instantiation"Reid Kleckner1-4/+0
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.

Summary: This patch implements main entry and auxiliary entries of symbol table generation for llvm-readobj on AIX. The source code of aix_xcoff_xlc_test8.o (compile with xlc) is: -bash-4.2$ cat test8.c extern int i; extern int TestforXcoff; extern int fun(int i); static int static_i; char* p="abcd"; int fun1(int j) { static_i++; j++; j=j+*p; return j; } int main() { i++; fun(i); return fun1(i); } Patch provided by DiggerLin Differential Revision: https://reviews.llvm.org/D65240 llvm-svn: 370097
2019-08-15[llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere1-1/+1
Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
2019-08-12[XCOFF] Use a single symbolic constant for the size of an embeded name. [NFC]Sean Fertile1-9/+9
Convert SymbolNameSize and SectionNameSize into just `NameSize`. The length of a name embeded in a symbol table entry or section header table entry is length 8 for Sections, Symbols and Files. No need to have a distinct constant for each one. Also removes the Size argument to 'generateStringRef' as the size is always 'XCOFF::NameSize'. llvm-svn: 368584

2019-07-09[Object][XCOFF] Add support for 64-bit file header and section header dumping.Sean Fertile1-149/+253
Adds a readobj dumper for 32-bit and 64-bit section header tables, and extend support for the file-header dumping to include 64-bit object files. Also refactors the binary file parsing to be done in a helper function in an attempt to cleanup error handeling. Differential Revision: https://reviews.llvm.org/D63843 llvm-svn: 365524

2019-05-14[Object] Change ObjectFile::getSectionContents to return ↵Fangrui Song1-3/+2
Expected<ArrayRef<uint8_t>> Change std::error_code getSectionContents(DataRefImpl, StringRef &) const; to Expected<ArrayRef<uint8_t>> getSectionContents(DataRefImpl) const; Many object formats use ArrayRef<uint8_t> as the underlying type, which is generally better than StringRef to represent binary data, so change the type to decrease the number of type conversions.

2019-05-03[Object][XCOFF] Add an XCOFF dumper for llvm-readobj.Sean Fertile1-7/+34

XCOFF object files are added to test dumping a well formed file, and dumping both negative timestamps and negative symbol counts, both of which are allowed in the XCOFF definition.
