  • Log message:
    Some changes to support early branching: branches are now ADD #x,PC instructions
    instead of MOV #x(PC),PC--providing greater range to the CPU. When that range
    is insufficient, ZPARSER now recognizes long jump instructions coded as
    LOD (PC),PC followed by the jump address. (This change was made necessary by
    the need to build an assembler/linker that could create instructions that would
    jump to any address in the 32-bit address space. In short, a part of the
    ongoing GCC upgrade and rework.)
