silly question: z80 and 68k cycles.

ldscript
I've got my ldscript down to: SECTIONS { .text 0x00000000: { *(.text) . = ALIGN(0x4); *(.rodata) } .data : { . = ALIGN(0x4); *(.data) } .bss 0xff0000 : { *(.bss) } } Does anyone else have anything smaller? Basically I don't initialize data on declaration- a minor inconvenience
