py: Implement bl/bx instructions for inline Thumb assembler. 2015-02-16 13:17:07 -05:00			`# test bl and bx instructions`

tests: Format all Python code with black, except tests in basics subdir. This adds the Python files in the tests/ directory to be formatted with ./tools/codeformat.py. The basics/ subdirectory is excluded for now so we aren't changing too much at once. In a few places `# fmt: off`/`# fmt: on` was used where the code had special formatting for readability or where the test was actually testing the specific formatting. 2020-03-22 22:26:08 -04:00
