| | | | | | | | | | | | | | | | | | | | | executables/shared libraries" Summary: This patch implements copying some load commands that appear in executables/shared libraries such as the indirect symbol table. I don't add tests intentionally because this patch is incomplete: we need a layout algorithm for executables/shared libraries. I'll submit it as a separate patch with tests.

* [llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere2019-08-151-2/+2
| | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | Summary: Recompute and update offset/size fields so that we can implement llvm-objcopy options like --only-section. This patch is the first step and focuses on supporting load commands that covered by existing tests: executable files and dynamic libraries are not supported.

* [Object] Change ObjectFile::getSectionContents to return ↵Fangrui Song2019-05-141-5/+6
| | | | | | | | | | | | | | | | | | | 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.
