* Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker2022-01-011-1/+1
| | | | | | | | This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
* Update copyright year range in all GDB filesJoel Brobecker2021-01-011-1/+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.
* Implement the skip_solib_resolver gdbarch hook for FreeBSD architectures.John Baldwin2020-07-201-0/+5
| | | | | | | | | | | | | | | The ELF runtime linker on all FreeBSD architectures uses the "_rtld_bind" entry point for unresolved PTL entries. FreeBSD/mips has an additional entry point called "_mips_rtld_bind". gdb/ChangeLog: * fbsd-tdep.c (fbsd_skip_solib_resolver): New function. (fbsd_init_abi): Install gdbarch "skip_solib_resolver" method. * fbsd-tdep.h (fbsd_skip_solib_resolver): New prototype. * mips-fbsd-tdep.c (mips_fbsd_skip_solib_resolver): New function. (mips_fbsd_init_abi): Install gdbarch "skip_solib_resolver" method.

* Add a helper function to resolve TLS variable addresses for FreeBSD.John Baldwin2019-03-121-0/+11
| | | | | | | | | | | | | | | | | The fbsd_get_thread_local_address function accepts the base address of a thread's DTV array and the base address of an object file's link map and uses this to compute a TLS variable's address. FreeBSD architectures use an architecture-specific method to determine the address of the DTV array pointer and call this helper function to perform the rest of the address calculation. * fbsd-tdep.c (fbsd_pspace_data_handle): New variable. (struct fbsd_pspace_data): New type. (get_fbsd_pspace_data, fbsd_pspace_data_cleanup) (fbsd_read_integer_by_name, fbsd_fetch_rtld_offsets) (fbsd_get_tls_index, fbsd_get_thread_local_address): New function. (_initialize_fbsd_tdep): Initialize 'fbsd_pspace_data_handle'. * fbsd-tdep.c (fbsd_get_thread_local_address): New prototype.
* Update copyright year range in all GDB files.Joel Brobecker2019-01-011-1/+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.
* Share the code to format "info proc mappings" entries for FreeBSD.John Baldwin2018-10-171-6/+17
| | | | | | | | | | | | | | | gdb/ChangeLog: * fbsd-nat.c (fbsd_nat_target::info_proc) Use fbsd_info_proc_mappings_header and fbsd_info_proc_mappings_entry. * fbsd-tdep.c (fbsd_vm_map_entry_flags): Mark static. (fbsd_info_proc_mappings_header, fbsd_info_proc_mappings_entry): New functions. (fbsd_core_info_proc_mappings): Use fbsd_info_proc_mappings_header and fbsd_info_proc_mappings_header. * fbsd-tdep.h (fbsd_vm_map_entry_flags): Remove. (fbsd_info_proc_mappings_header, fbsd_info_proc_mappings_entry): New.
* Add support for 'info proc files' on FreeBSD core dumps.John Baldwin2018-09-181-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Walk the list of struct kinfo_file objects in the NT_FREEBSD_PROCSTAT_FILES core dump note outputting a description of each open file descriptor. For sockets, the local and remote socket addresses are displayed in place of the file name field. For UNIX local domain sockets, only a single address is displayed since most UNIX sockets only have one valid address and printing both pathnames could be quite long. The output format was somewhat inspired by the output of the "procstat -f" command on FreeBSD, but with a few less details and some fields were condensed. gdb/ChangeLog: * fbsd-tdep.c (KF_FLAGS, KF_OFFSET, KF_VNODE_TYPE, KF_SOCK_DOMAIN) (KF_SOCK_TYPE, KF_SOCK_PROTOCOL, KF_SA_LOCAL, KF_SA_PEER) (KINFO_FILE_TYPE_SOCKET, KINFO_FILE_TYPE_PIPE) (KINFO_FILE_TYPE_FIFO, KINFO_FILE_TYPE_KQUEUE) (KINFO_FILE_TYPE_CRYPTO, KINFO_FILE_TYPE_MQUEUE) (KINFO_FILE_TYPE_SHM, KINFO_FILE_TYPE_SEM, KINFO_FILE_TYPE_PTS) (KINFO_FILE_TYPE_PROCDESC, KINFO_FILE_FD_TYPE_ROOT) (KINFO_FILE_FD_TYPE_JAIL, KINFO_FILE_FD_TYPE_TRACE) (KINFO_FILE_FD_TYPE_CTTY, KINFO_FILE_FLAG_READ) (KINFO_FILE_FLAG_WRITE, KINFO_FILE_FLAG_APPEND) (KINFO_FILE_FLAG_ASYNC, KINFO_FILE_FLAG_FSYNC) (KINFO_FILE_FLAG_NONBLOCK, KINFO_FILE_FLAG_DIRECT) (KINFO_FILE_FLAG_HASLOCK, KINFO_FILE_FLAG_EXEC) (KINFO_FILE_VTYPE_VREG, KINFO_FILE_VTYPE_VDIR) (KINFO_FILE_VTYPE_VCHR, KINFO_FILE_VTYPE_VLNK) (KINFO_FILE_VTYPE_VSOCK, KINFO_FILE_VTYPE_VFIFO, FBSD_AF_UNIX) (FBSD_AF_INET, FBSD_AF_INET6, FBSD_SOCK_STREAM, FBSD_SOCK_DGRAM) (FBSD_SOCK_SEQPACKET, FBSD_IPPROTO_ICMP, FBSD_IPPROTO_TCP) (FBSD_IPPROTO_UDP, FBSD_IPPROTO_SCTP): New defines.

* Add multi-arch capable 'fbsd_make_corefile_notes' variantAndreas Arnez2014-09-301-0/+25
This creates a new version of the FreeBSD core file note generation logic in the new target-dependent file "fbsd-tdep.c". The new version is mostly copied from "fbsd-nat.c", but uses the iterator instead of regset_from_core_section and defines fbsd_make_corefile_notes as a gdbarch method instead of a target method. Consecutive architecture-dependent changes exploit the new version, migrating away from the target method. When all FreeBSD targets are changed, the target method can go away. gdb/ChangeLog: * fbsd-tdep.c: New file. * fbsd-tdep.h: New file. * Makefile.in (ALL_TARGET_OBS): Add fbsd-tdep.o. (HFILES_NO_SRCDIR): Add fbsd-tdep.h. (ALLDEPFILES): Add fbsd-tdep.c.
