- Subject: Multiple breakpoint locations
The new code for breakpoints with multiple locations looks very good and
addresses a common complaint about GDB. I have a couple of points and
apologise if they have already been discussed.
Folowing the example in the manual:
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
stop only if i==1
breakpoint already hit 1 time
1.1 y 0x080486a2 in void foo<int>() at t.cc:8
1.2 y 0x080486ca in void foo<double>() at t.cc:8
1) I can enable/disable 1.1 and 1.2 but not delete them:
(gdb) dis 1.1
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
stop only if i==1
breakpoint already hit 1 time
1.1 n 0x080486a2 in void foo<int>() at t.cc:8
1.2 y 0x080486ca in void foo<double>() at t.cc:8
(gdb) d 1.1
warning: bad breakpoint number at or near '1.1'
2) I can enable/disable 1 and this appears to enable/disable all the locations.
Perhap this could be documented in the manual.
3) I created this breakpoint by specifying the line but if I do:
b foo<int>()
or any variant I can think of, I just get a pending breakpoint as GDB
doesn't recognise the location. Can such locations be specified on the
command line by name?
