And a small utilities -- extract-section.py -- that helps extracting specific object file section and printing in textual format. This utility is just a workaround for tests inside `Encoding`. Hopefully in the future we can replace dependencies in those tests with existing tools (e.g. llvm-readobj). Please refer to this bug for more context: https://bugs.llvm.org/show_bug.cgi?id=49245 Note that since we don't have AsmParser for now, we are testing the MC part using MIR as input and put those tests under the `Encoding` folder. In the future when AsmParser (and disassembler) is finished, those tests will be moved to `test/MC/M68k`. Authors: myhsu, m4yers, glaubitz Differential Revision: https://reviews.llvm.org/D88392
