Re: [RFA]: error_silent for use in pending breakpoint support


Jeff Johnston wrote:
To properly support pending breakpoints, gdb needs to be able to suppress the "not found" messages at will, but it also needs to sometimes issue these messages and determine the cause of the error was a "not found" event.

To handle the problem, I propose two new useful functions in utils.c. The first is error_silent() which works just like error(), only it does not issue the error message. Like error(), it stores the error message in gdb_lasterr. This leads to the other new function: error_last_output() which is used to output the last error message.

This allows the pending breakpoint support to issue the error message when the user is doing the initial break command and to suppress it when shared libraries are being loaded or a pending breakpoint is reenabled.

Ok to commit?

       * linespec.c (decode_variable, symtab_from_filename):  Call
       error_silent with error message instead of throwing an exception
       * defs.h (error_silent, error_last_output): Add prototypes.
       * utils.c (error_silent, error_last_output): New functions.
