Switch/Case Statement debugging / tracing

zdjohnson — Fri, 24 Jul 2015 15:46:48 GMT

Case statements are apparently optimized down to a jump table which prevents me from setting a breakpoint onto a particular case in the switch statement.

1) How can I set a breakpoint to a particular case in a switch statement?

2) How does one change the level of optimization applied in the compile step or set options like bounds checking etc?

Thanks for any help.

I am using CodeWarrior CW_MCU_V6_3_SE with Freescale MC9S08QE64 (HCS08).

hi,

1. we can't set a breakpoint as specific code such as case 0:.

here is a piece of disassemble code i extracted for switch...case

we can see there is no "real" disassembly code allocated in memory for "case 0". so it's not possiable to set a breakpoint at this line.

2. CW for HCS08 doesn't define a optimization level. but we can disable optimization in compiler option settings

can this help you?

Have a great day,
Zhang Jun
