mac68k-asm 1.2.1

Fixed in 1.2.1: short branches inside a macro stay short.

A macro call is one source line, but its expansion can hold several branches. When one of them had to be long (for example an unsized forward BMI, which is .W), every Bcc.S after it in the same expansion was widened too, with a wrong "does not reach its target" warning. Each branch is now sized on its own. Code without macros is unchanged: 104 projects build to identical bytes.

Install: sudo apt install ./mac68k-asm_1.2.1_arm64.deb (or _amd64.deb), or brew install bircher988/tap/mac68k-asm.

mac68k-asm 1.2

New in 1.2: the resource compiler knows the RMaker formats

• Type XXXX = STR - one line of text as a Pascal string, e.g. an application's signature resource (the trailing space of the original spelling is optional),
• Type FREF - <file type> <local icon ID> [<file name>],

byte for byte as the original MDS RMaker makes them (a regression test compares with its output). The README describes the .R formats, with an application icon as the example.

Install: sudo apt install ./mac68k-asm_1.2_arm64.deb (or _amd64.deb), or brew install bircher988/tap/mac68k-asm.

mac68k-asm 1.1

Breaking change: a DS variable named on its own may now only be read (MOVE.W Var,D0, CMP, BTST, LEA, PEA). Where the operand must be alterable - a destination, CLR, TST, ADDQ, BSET, ... - write the base register: MOVE.W D0,Var(A5). It is the same instruction as before, and the error names the fix for each line (write WindPtr(A5)).

Also in 1.1:

• Fix: "assembly does not converge" - a forward Bcc.S over one instruction could be widened for good and push the next one, one per pass.
• Applications with a BNDL resource get the Finder's hasBundle flag, so their icons show.
• Operand errors are reported once instead of once per pass.
• The .deb recommends mac68k-disk (hfsutils is no longer packaged in Debian 13).
