Two things changed: (1) string literals can now hold backslash
escapes like "\n"; (2) MVN/MVP operands can now be prefixed with '#'.
The former was a breaking change because any string with "\" must
be changed to "\\". This is now handled by the string operand
formatter.
Also, improved test harness output. Show the assembler versions at
the end, and include assembler failure messages in the collected
output.
The regression tests were written with the assumption that all cross
assemblers would support 6502, 65C02, and 65816 code. There are a
few that support 65816 partially (e.g. ACME) or not at all. To best
support these, we need to split some of the tests into pieces, so
that important 6502 tests aren't skipped simply because parts of the
test also exercise 65816 code.
The first step is to change the regression test naming scheme. The
old system used 1xxx for tests without project files, and 2xxx for
tests with project files. The new system uses 1xxxN / 2xxxN, where
N indicates the CPU type: 0 for 6502, 1 for 65C02, and 2 for 65816.
For the 1xxxN tests the new value determines which CPU is used,
which allows us to move the "allops" 6502/65C02 tests into the
no-project category. For 2xxxN it just allows the 6502 and 65816
versions to have the same base name and number.
This change updates the first batch of tests. It involves minor
changes to the test harness and a whole bunch of renaming.
