Subject: [PATCH v2 00/10] Add minimal NetBSD/amd64 gdbserver support
Date: Fri, 4 Sep 2020 02:28:55 +0200 [thread overview]
Message-ID: <20200904002905.13616-1-n54@gmx.com> (raw)
Extract reusable functionality from gdb/nbsd-nat.c into
gdb/nat/netbsd-nat.c and switch the gdb/nbsd-nat.c functions
(nbsd_nat_target::pid_to_exec_file, nbsd_nat_target::thread_alive,
nbsd_nat_target::thread_name, nbsd_nat_target::post_startup_inferior,
nbsd_nat_target::post_attach, nbsd_nat_target::xfer_partial,
nbsd_add_threads) to gdb/nat.
Add handle_eintr in gdbsupport to wrap syscalls and EINTR handling.
Add NetBSD/amd64 gdbserver support
Implement the following functionality: create_inferior,
post_create_inferior, attach, kill, detach, mourn, join, thread_alive,
resume, wait, fetch_registers, store_registers, read_memory, write_memory,
request_interrupt, supports_read_auxv, read_auxv,
supports_hardware_single_step, sw_breakpoint_from_kind,
supports_z_point_type, insert_point, remove_point,
stopped_by_sw_breakpoint, supports_qxfer_siginfo, qxfer_siginfo,
supports_stopped_by_sw_breakpoint, supports_non_stop,
supports_multi_process, supports_fork_events, supports_vfork_events,
supports_exec_events, supports_disable_randomization,
supports_qxfer_libraries_svr4, qxfer_libraries_svr4,
supports_pid_to_exec_file, pid_to_exec_file, thread_name,
supports_catch_syscall.
The only CPU architecture supported: x86_64.
Implement only support for hardware assisted single step and
software breakpoint.
Implement support only for regular X86 registers, thus no FPU.
Changes in v2:
* handle_eintr downgraded from C++14 to C++11 and allow predefining the
value of failure.
* Enhance ChangeLog entries.
* Remove srv_netbsd from /gdbserver/configure.srv.
* Enhance wording and code style.
* Remove function return type from netbsd_add_process().
* Rename netbsd_nat::list_threads to netbsd_nat::for_each_thread.
* Return error on failure in netbsd_process_target::kill.
* Use core_addr_to_string() when printing CORE_ADDR.
* Switch from (*target). to target->.
* Simplify netbsd_process_target::sw_breakpoint_from_kind.
* Remove netbsd_target_ops::process_qsupported() and
x86_64_netbsd_update_xmltarget().
Kamil Rytarowski (10):
Add handle_eintr to wrap EINTR handling in syscalls
Register a placeholder for NetBSD shared functions in gdb/nat
Build nat/netbsd-nat.o for the NetBSD native target
Add netbsd_nat::pid_to_exec_file
Add gdb/nat common functions for listing threads
Add netbsd_nat::enable_proc_events in gdb/nat
Add a common utility function to read and write siginfo_t in inferior
Avoid double free in startup_inferior
Switch local native code to gdb/nat shared functions
Add minimal and functional NetBSD/amd64 gdbserver
