Fix PR gdb/19858: GDB doesn't register the JIT libraries on attach
Ref: https://sourceware.org/ml/gdb/2016-03/msg00023.html
GDB currently fails to fetch the list of already-registered JIT
modules on attach.
Nothing is calling jit_inferior_init, which is what is responsible for
walking the JIT object list at init time.
Despite the misleading naming, jit_inferior_created_hook ->
jit_inferior_init is only called when the inferior execs.
This regressed with the fix for PR gdb/13431 (03bef283c2d3):
https://sourceware.org/ml/gdb-patches/2012-02/msg00023.html which
removed the inferior_created (jit_inferior_created_observer)
observer.
Adding an inferior_created observer back fixes the issue.
In turn, this exposes a bug in jit_breakpoint_re_set_internal as well,
which is returning the wrong result when we already have the
breakpoint at the right address.
gdb/ChangeLog:
2016-03-31 Yichao Yu <yyc1992@gmail.com>
PR gdb/19858
* jit.c (jit_breakpoint_re_set_internal): Return 0 if we already
got the breakpoint at the right address.
(jit_inferior_created): New function.
(_initialize_jit): Install jit_inferior_created as
inferior_created observer.
