* Fix disasm treatment of branch offsetsDavid Phillips2019-08-03
| | | | | This patch makes the disassembler treat branch offsets as PC-relative rather than absolute.

* Add some (failing) testsDavid Phillips2019-08-03

* Tidy test runner scriptDavid Phillips2019-08-03
| | | | | | | Makes no-clean mode optional, and non-default. By default, we probably want failed test runs not to leave things lying around, since most of test running for now will be for test development. Perhaps once tests are stable, we can switch back to no-clean by default to catch bugs.
* Add test for asm-disasm-asm, fix bug with labelsDavid Phillips2019-08-03
| | | | | | | | | | | | | | This adds a support script for future expansion of an asm->disasm->asm series of tests, which will at minimum ensure some parity between the assembler and disassembler. Lower level tests to ensure correct behaviour rather than just symmetrical behaviour belong in another set of tests. This patch also fixes the assembler's behaviour around numeric labels. Many other assemblers support entirely numeric labels, and the output of the disassembler includes them. The assembler has been adjusted to lex a probably-numeric as a label if it is at the start of the line. Otherwise, old label behavour and old numeric behaviour is left in place.
