The double loop lets us correctly handle code "break"ing out of the
|
|
|
|
try catch block. (It works as the "break" only exits the inner
|
|
|
|
"while" loop, the outer for loop detects this handling it
|
|
|
|
correctly.) Of course "return" and "goto" are not so lucky.

Code normally throws an exception using error() et.al. For various
|
|
|
|
reaons, GDB also contains code that throws an exception directly.
|
|
|
|
For instance, the remote*.c targets contain CNTRL-C signal handlers
|
|
|
|
that propogate the QUIT event up the exception chain. ``This could

/* Call FUNC(UIOUT, FUNC_ARGS) but wrapped within an exception
|
|
|
|
handler. If an exception (enum return_reason) is thrown using
|
|
|
|
throw_exception() than all cleanups installed since
|
|
|
|
catch_exceptions() was entered are invoked, the (-ve) exception
|
|
|
|
value is then returned by catch_exceptions. If FUNC() returns
|
|
|
|
normally (with a postive or zero return value) then that value is
|
|
|
|
returned by catch_exceptions(). It is an internal_error() for
|
|
|
|
FUNC() to return a negative value.
|
|
|
|
|
|
|
|
For the period of the FUNC() call: UIOUT is installed as the output
|
|
|
|
builder; ERRSTRING is installed as the error/quit message; and a
|
|
|
|
new cleanup_chain is established. The old values are restored
|
|
|
|
before catch_exceptions() returns.
|
|
|
|
|
|
|
|
The variant catch_exceptions_with_msg() is the same as
|
|
|
|
catch_exceptions() but adds the ability to return an allocated
|
|
|
|
copy of the gdb error message. This is used when a silent error is
|
|
|
|
issued and the caller wants to manually issue the error message.
