Fix lost siginfo_t for inferior calls. * infrun.c (struct inferior_thread_state) <siginfo_gdbarch, siginfo_data>: New. (save_inferior_thread_state): New variables regcache, gdbarch and siginfo_data. Initialize SIGINFO_DATA if gdbarch_get_siginfo_type_p. Move INF_STATE allocation later, pre-clear it. Initialize REGISTERS using REGCACHE. (restore_inferior_thread_state): New variables regcache and gdbarch. Restore SIGINFO_DATA for matching GDBARCH. Restore REGISTERS using REGCACHE. Free also SIGINFO_DATA. gdb/testsuite/ Fix lost siginfo_t for inferior calls. * gdb.base/siginfo-infcall.exp: New file. * gdb.base/siginfo-infcall.c: New file.
