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 (03bef283): 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. Signed-off-by: Pedro Alves <palves@redhat.com>
