[llvm-tapi] initial commit, supports ELF text stubs
http://lists.llvm.org/pipermail/llvm-dev/2018-September/126472.html
TextAPI is a library and accompanying tool that allows conversion between binary shared object stubs and textual counterparts. The motivations and uses cases for this are explained thoroughly in the llvm-dev proposal [1]. This initial commit proposes a potential structure for the TAPI library, also including support for reading/writing text-based ELF stubs (.tbe) in addition to preliminary support for reading binary ELF files. The goal for this patch is to ensure the project architecture appropriately welcomes integration of Mach-O stubbing from Apple's TAPI [2].
Added:
- TextAPI library
- .tbe read support
- .tbe write (to raw_ostream) support
