Subject: Breakpoint commands compiler
Date: Fri, 17 Oct 2014 15:42:00 -0000	[thread overview]
Message-ID: <CAF5HaEVWapj-ZVTshW7aGdjFhmMohZqw9dCezwTrxH__FSEkLg@mail.gmail.com> (raw)

Hi,

    gdb is sometimes used for changing the runtime behavior of a program.
That is, suppose there is a program that has a bug,
it is spotted with gdb, then I create a set of non-stopping breakpoints that
"fix" the runtime behavior by altering memory and registers.
It does work, but it's slow.

I was thinking to start a project to add a "breakpoint commands compiler"
to gdb, which basically generates C code from the breakpoint commands
(one function per breakpoint),
which in turns calls a C API (similar to the python api), invokes the compiler
(user-specified), loads it as a shared object, and finally replaces the commands
of the breakpoints by calls to the compiled breakpoint-functions.

Any comment/suggestion? Would this be accepted within gdb?

Thanks,

    Daniel.
