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			`@micropython.asm_thumb # test vcmp, vmrs`
py/inlinethumb: Support for core floating point instructions. Adds support for the following Thumb2 VFP instructions, via the option MICROPY_EMIT_INLINE_THUMB_FLOAT: vcmp vsqrt vneg vcvt_f32_to_s32 vcvt_s32_to_f32 vmrs vmov vldr vstr vadd vsub vmul vdiv 2015-04-14 08:14:57 -04:00			`def f(r0, r1):`
