are used. Delete or disable unused hardware
breakpoints before setting new ones (see
“Disabling breakpoints” (page 58)). See “Break
conditions” (page 59).
thbreak args
Set a hardware-assisted breakpoint enabled only
for one stop. args are the same as for the hbreak
command and the breakpoint is set in the same
way. However, like the tbreak command, the
breakpoint is automatically deleted after the first
time your program stops there. Also, like the
hbreak command, the breakpoint requires
hardware support and some target hardware may
not have this support. See “Disabling breakpoints”
(page 58). See also “Break conditions” (page 59).
rbreak regex
Set breakpoints on all functions matching the
regular expression regex. This command sets an
unconditional breakpoint on all matches, printing
a list of all breakpoints it set. Once these
breakpoints are set, they are treated just like the
breakpoints set with the break command. You
can delete them, disable them, or make them
conditional the same way as any other breakpoint.
The syntax of the regular expression is the
standard one used with tools like 'grep'. Note that
this is different from the syntax used by shells, so
for instance foo* matches all functions that
include an fo followed by zero or more os. There
is an implicit .* leading and trailing the regular
expression you supply, so to match only functions
that begin with foo, use ^foo.
When debugging C++ programs, rbreak is useful
for setting breakpoints on overloaded functions
that are not members of any special classes.
