2013-05-23range stepping: gdbserver (x86 GNU/Linux)Pedro Alves1-0/+5
This patch adds support for range stepping to GDBserver, teaching it about vCont;r. It'd be easy to enable this for all hardware single-step targets without needing the linux_target_ops hook, however, at least PPC needs special care, due to the fact that PPC atomic sequences can't be hardware single-stepped through, a thing which GDBserver doesn't know about. So this leaves the support limited to x86/x86_64. gdb/ 2013-05-23 Pedro Alves <palves@redhat.com> * NEWS: Mention GDBserver range stepping support. gdb/gdbserver/ 2013-05-23 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * linux-low.c (lwp_in_step_range): New function.

2013-05-23range stepping: gdbPedro Alves1-0/+17
This patch teaches GDB to take advantage of target-assisted range stepping. It adds a new 'r ADDR1,ADDR2' action to vCont (vCont;r), meaning, "step once, and keep stepping as long as the thread is in the [ADDR1,ADDR2) range". Rationale: When user issues the "step" command on the following line of source, a = b + c + d * e - a; GDB single-steps every single instruction until the program reaches a new different line. E.g., on x86_64, that line compiles to: 0x08048434 <+65>: mov 0x1c(%esp),%eax 0x08048438 <+69>: mov 0x30(%esp),%edx 0x0804843c <+73>: add %eax,%edx 0x0804843e <+75>: mov 0x18(%esp),%eax 0x08048442 <+79>: imul 0x2c(%esp),%eax 0x08048447 <+84>: add %edx,%eax 0x08048449 <+86>: sub 0x34(%esp),%eax 0x0804844d <+90>: mov %eax,0x34(%esp) 0x08048451 <+94>: mov 0x1c(%esp),%eax and the following is the RSP traffic between GDB and GDBserver: --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3c840408;thread:p2e13.2e13;core:1; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3e840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:42840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:47840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:49840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:4d840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2e13.2e13;core:0; IOW, a lot of roundtrips between GDB and GDBserver. If we add a new command to the RSP, meaning "keep stepping and don't report a stop until the program goes out of the [0x08048434, 0x08048451) address range", then the RSP traffic can be reduced down to: --> vCont;r8048434,8048451:p2db0.2db0;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2db0.2db0;core:1; As number of packets is reduced dramatically, the performance of stepping source lines is much improved. In case something is wrong with range stepping on the stub side, the debug info or even gdb, this adds a "set/show range-stepping" command to be able to turn range stepping off. gdb/ 2013-05-23 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_control_state) <may_range_step>: New field. * infcmd.c (step_once, until_next_command): Enable range stepping. * infrun.c (displaced_step_prepare): Disable range stepping.
