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.
