Rationalize "fatal" error handling outside of gdbserver
GDB and gdbserver have functions named "fatal" that are used in completely different ways. In gdbserver "fatal" is used to handle critical errors: it differs from "error" in that "fatal" causes gdbserver to exit whereas "error" does not. In GDB "fatal" is used to abort the current operation and return to the command level. This is implemented by throwing a non-error "RETURN_QUIT" exception. This commit removes GDB's "fatal" and "vfatal" functions entirely. The exception-throwing function "throw_vfatal" is renamed as "throw_vquit", and a new convenience function "throw_quit" is added. The small number of calls to "fatal" are replaced with calls to "throw_quit", making what is happening more obvious. This commit also modifies GDB's "throw_error" to call "throw_verror" rather than calling "throw_it" directly. This change means the assignment of RETURN_ERROR as the exception type now happens in precisely one place in GDB rather than two. gdb/ 2014-07-24 Gary Benson <gbenson@redhat.com> * exceptions.h (throw_vfatal): Renamed to... (throw_vquit): New declaration. (throw_quit): Likewise. * exceptions.c (throw_vfatal): Renamed to... (throw_vquit): New function. (throw_quit): Likewise. (throw_error): Call throw_verror rather than throw_it. * utils.h (vfatal): Removed. (fatal): Likewise. * utils.c (vfatal): Removed. (fatal): Likewise. (internal_verror): Replaced call to fatal with call to throw_quit. (quit): Replaced calls to fatal with calls to throw_quit.
