Move the debug register support code from amd64bsd-nat.c and i386bsd-nat.c into a shared x86bsd-nat.c. Instead of setting up x86_dr_low in amd64fbsd-nat.c and i386fbsd-nat.c, add a x86bsd_target function that creates a new target that inherits from inf_ptrace and sets up x86 debug registers if supported. In addition to initializing x86_dr_low, the x86bsd target installs a custom mourn_inferior target operation to clean up the x86 debug register state. Previously this was only done on amd64. Now it will be done for both i386 and amd64. The i386bsd_target and amd64bsd_target functions create targets that inherit from x86bsd rather than inf_ptrace. gdb/ChangeLog: * Makefile.in [HFILES_NO_SRCDIR]: Replace 'amd64bsd-nat.h' with 'x86bsd-nat.h'. * amd64bsd-nat.c: Include 'x86bsd-nat.h' instead of 'amd64bsd-nat.h'.
