enable
(enable breakpoint)
disable
(disable breakpoint) [ICD Mini / SIM]
Operation
enable
: Enables a currently disabled breakpoint to make it effective again.
disable
: Disables a currently effective breakpoint to make it ineffective.
Breakpoints are effective when set by a break command and remain effective. The
disable
command disables
these breakpoints without deleting them. Once disabled, the breakpoints are ineffective and the program does
not break until said breakpoints are reenabled by the
enable
command.
Format
enable [
BreakNo
]
disable [
BreakNo
]
BreakNo : Break number (decimal or hexadecimal)
When this entry is omitted, all breakpoints are disabled or enabled.
Usage example
(gdb) info breakpoints (displays a breakpoint list.)
Num Type Disp Enb Address What
1 breakpoint keep y 0x00c0001c in main at main.c:7
2 breakpoint keep y 0x00c0001e in main at main.c:10
3 breakpoint keep y 0x00c00028 in main at main.c:13
4 breakpoint keep y 0x00c00038 in sub at main.c:20
Let's assume that breakpoints have been set as shown above. The effective breakpoints are marked by '
y
' in the
Enb
column.

1 breakpoint keep n 0x00c0001c in main at main.c:7
2 breakpoint keep y 0x00c0001e in main at main.c:10
3 breakpoint keep n 0x00c00028 in main at main.c:13
4 breakpoint keep y 0x00c00038 in sub at main.c:20
When executing the
disable
command with a break number attached, note that only the specified break is disabled.
You can specify multiple break numbers at a time. Ineffective breakpoints are marked by '
n
' in the
Enb
column.

3 breakpoint keep y 0x00c00028 in main at main.c:13
4 breakpoint keep y 0x00c00038 in sub at main.c:20
When a break number is omitted, all breakpoints are enabled (or disabled) simultaneously.
