- 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.)
