Conditional breakpoints
conditional breakpoints are implemented in the following way:
- when a breakpoint is hit, the condition is run as a normal command
- if the command returns a value different from zero, execution continue,
- otherwise, execution is stopped at the breakpoint
Examples of conditional breakpoints
-
ignore breakpoint at address
0x4000ce
for five times:f times=5 (dec_times,f times=`?vi times-1`,?= times) db 0x4000ce dbC 0x4000ce .(dec_times) dc
-
execute until rax==0x31c0 at address
0x4000ce
e cmd.hitinfo=0 (break_rax,f reg_rax=`dr rax`,f test=`?vi reg_rax-0x31c0`,?= test) db 0x4000ce dbC 0x4000ce .(break_rax) dc
-
perform a register tracing dump at address
0x4000ce
e cmd.hitinfo=0 (trace_rax,dr rax,?= 1) db 0x4000ce dbC 0x4000ce .(trace_rax) dc > trace.txt
