When I use the GDB, I always think about insert breakpoint to
a file.
Then if inferior exec to any part of this file, the inferior
will be
break. But GDB simple break command doesn't support it.
Now, gdb-cvs-head have a new command rbreak:
`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 `o's. 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.
The `rbreak' command can be used to set breakpoints in *all*
the
functions in a program, like this:
(gdb) rbreak .
`rbreak FILE:REGEX'
If `rbreak' is called with a filename qualification, it limits
the
search for functions matching the given regular expression to
the
specified FILE. This can be used, for example, to set
breakpoints
on every function in a given file:
(gdb) rbreak file.c:.
The colon separating the filename qualifier from the regex
may
optionally be surrounded by spaces.
