Chapter 4   Optimization

Usage Example  55

Example: branch destination of conditional branch instruction within range

This example shows a branch in the permitted range (-128 to 127 of PC) of a BCC LABEL conditional

branch instruction. 

The source list is as follows.

The final list file after assembly is shown next. The start address during linking is assumed to be

40000000 (hex.). The @ mark on line number 6 indicates that the instruction was the object of optimi-

zation. Since the target address is within the range of a relative jump, the assembler generates a BCC

LABEL instruction.
