ca65: Fix '*' in operands of bit branch, block transfer and LDM
 2026-10-24 15:19:02 +02:00
Alex Volkov c629423f91 Fix a rare bug in BIT #imm instruction on 65C02 variants. The bug manifests as an extra operand byte after switching CPUs from 65816 in .a16 mode to 65C02 family. It was caused by incorrect AddrMode masks in 65C02 variant tables. 2026-10-22 22:00:03 -04:00
José Luis Oliveros HernándezandClaude Opus 5.5 8aa120967a ca65: Fix '*' in operands of bit branch, block transfer and LDM 
PutBitBranch, PutBitBranch_m740, PutBlockTransfer and PutLDM_m740 emitted
the opcode (and the zero page byte) before reading the remaining operands.
Since '*' is evaluated while the operand is read, it pointed one or two
bytes into the instruction instead of at its start:

    bbr0 $12,*          ; was 0F 12 FF, now 0F 12 FD (loops on itself)
    tii  *,$2000,1      ; source address was off by one
    ldm  $12,#<*        ; immediate was off by two

The usual "wait for a port bit" idiom `bbr0 port,*` therefore jumped into
the middle of the next instruction. Branches to labels were not affected.

Now all operands are read first and emitted afterwards, as for every other
instruction.

In addition, the m740 accumulator form `bbs/bbc i,a,rel` is a 2 byte
instruction, but its offset was computed relative to the end of a 3 byte
one, so it was off by one even with labels. da65 had the matching error
(PC+3 instead of PC+2) in OH_AccumulatorBitBranch, which is why the
round trip test did not catch it. Both are fixed.

Reference binaries that encoded the old offsets are regenerated: the only
differences are the 16 bit branch offsets in each file. The 65C02 da65
test used `bbrN $12,*+2` meaning "next instruction"; with correct '*'
that is `*+3`.

New test: test/asm/listing/313-bitbranch-star.s, with hand-computed bytes.
