clear
(clear break by break position) [ICD Mini / SIM]
Operation
Deletes PC breakpoints (including temporary breakpoints) currently set individually by specifying a set position
(function name, line number, or address).
Format
clear
[
Breakpoint
]
Breakpoint : Breakpoint
Can be specified by one of the following:
• Function name
• Source file name:line number or line number only
• *Address (decimal, hexadecimal, or symbol)
When this entry is omitted, all breakpoints set in the source that includes the current PC address
are deleted.
Conditions: 0

address
≤
0xfffffe
Usage example
(gdb) info breakpoints
(displays a breakpoint list.)
Num Type Disp Enb Address What
1 breakpoint keep y 0x00c0001e in main at main.c:10
2 breakpoint keep y 0x00c00038 in sub at main.c:20
3 breakpoint keep y 0x00c0003c in sub at main.c:22
4 breakpoint keep y 0x00c00042 in sub at main.c:22
Let's assume that breakpoints have been set as shown above. Although break numbers 3 and 4 are at different
addresses, the breakpoints are set on one line in terms of the C source. (This applies when breakpoints are set at
addresses displayed in ASSEMBLY mode.)
n
Example 1
(gdb) clear main.c:22
Deleted breakpoints 4 3
(gdb) info breakpoints
Num Type Disp Enb Address What
1 breakpoint keep y 0x00c0001e in main at main.c:10
2 breakpoint keep y 0x00c00038 in sub at main.c:20
When you specify a line number, all breakpoints set on the source line are cleared.
n
Example 2
(gdb) clear main
Deleted breakpoint 1
(gdb) info breakpoints
Num Type Disp Enb Address What
2 breakpoint keep y 0x00c00038 in sub at main.c:20
When you specify a function name, the breakpoint set in the first C instruction within the function (expanded to
mnemonic) is cleared. Use this method to delete breakpoints that have been set by "break function name", etc.
n
Example 3
(gdb) clear
Deleted breakpoint 2
(gdb) info breakpoints
No breakpoints or watchpoints.
When parameters are omitted, all breakpoints set in the source that includes the address displayed on the
current PC (
main.c
in this example) are deleted. If no breakpoints are set in the source, the "No source file
specified." message appears, with no breakpoints being deleted.
