Changes to hexdump "struct user" for child process on some configurations
that use ptrace(). This is not as useful as doing a full dump in a human readable format, but is better than nothing when you are trying to verify what is actually in the user struct. * infptrace.c (udot_info): New function. (PT_*): Define each individually if that one is not defined. Update copyright to 1996. * rs6000-nat.c (kernel_u_size): New function Include <sys/user.h> for "struct user" Update copyright to 1996. * alpha-nat.c (kernel_u_size): New function. Include <sys/user.h> for "struct user" Update copyright to 1996. * sparc-nat.c (kernel_u_size): New function.
