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.

; Example inspired by incorrect analysis...

|

|
|
; beq {+03} ;jumps to the $8f
|
|
; lda #$00
|
|
; brk $8f
|
|
; and stops, then pursues the branch. If we try to walk from top
|
|
; to bottom, skipping forward by the full length of an instruction,
|
|
; we'll appear to find ourselves in the middle of an embedded
|
|
; instruction.
|
|
;
|
|
; This is different from the typical embedded instruction,
|
|
; where the inner is contained entirely within the outer.

; The code analyzer sees two paths, involving the three bytes.
|
|
; The first is the three-byte JSR, the second is the one-byte
|
|
; RTS. The third NOP byte is never "executed" by the analyzer,
|
|
; but because of the way we display embedded instructions it
|
|
; gets put on its own line. Since it's not an instruction start
|
|
; or a data item, things get confused. (This is referred to as

|
; an "embedded orphan" in the code.)
