2021-01-01Update copyright year range in all GDB filesJoel Brobecker1-1/+1
This commits the result of running gdb/copyright.py as per our Start of New Year procedure... gdb/ChangeLog Update copyright year range in copyright header of all GDB files.
2020-08-03Update FreeBSD system calls for 13.0-CURRENT.John Baldwin1-2/+15
This matches the current set of system calls in the FreeBSD head development branch as of r363367. Some of these system calls were also included in 12.1 release. gdb/ChangeLog: * syscalls/freebsd.xml: Regenerate.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-12-13Update the FreeBSD system call table to match FreeBSD 12.0.John Baldwin1-23/+87
Add a script to generate the FreeBSD XML system call table from the sys/sys/syscall.h file in the kernel source tree. For ABI compatiblity system calls used by older binaries (such as freebsd11_kevent()), the original system call name is used as an alias. Run this script against the current syscall.h file in FreeBSD's head branch which is expected to be the file used in 12.0 (head is currently in code freeze as part of the 12.0 release process). gdb/ChangeLog: * syscalls/update-freebsd.sh: New file. * syscalls/freebsd.xml: Regenerate.

2016-06-24Add support for catching system calls to native FreeBSD targets.John Baldwin1-0/+410
All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events. [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE] (fbsd_set_syscall_catchpoint): New function. (fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.
