* jit.c (struct jit_inferior_data) <cached_code_address, jit_breakpoint>: New fields. (jit_breakpoint_re_set_internal): Fix logging. Only create breakpoint if cached address has changed. (jit_update_inferior_cache, jit_breakpoint_deleted): New functions. (_initialize_jit): Register breakpoint deleted observer. gdb/testsuite * gdb.base/jit.exp (compile_jit_test): New proc. Add PIE tests.
