@item CHILD_PREPARE_TO_STORE
@findex CHILD_PREPARE_TO_STORE
If the machine stores all registers at once in the child process, then
define this to ensure that all values are correct. This usually entails
a read from the child.
[Note that this is incorrectly defined in @file{xm-@var{system}.h} files
currently.]
@item FETCH_INFERIOR_REGISTERS
@findex FETCH_INFERIOR_REGISTERS
Define this if the native-dependent code will provide its own routines
@code{fetch_inferior_registers} and @code{store_inferior_registers} in
@file{@var{host}-nat.c}. If this symbol is @emph{not} defined, and
@file{infptrace.c} is included in this configuration, the default
routines in @file{infptrace.c} are used for these functions.
@item int gdbarch_fp0_regnum (@var{gdbarch})
@findex gdbarch_fp0_regnum
This functions normally returns the number of the first floating
point register, if the machine has such registers. As such, it would
appear only in target-specific code. However, @file{/proc} support uses this
to decide whether floats are in use on this target.
@item int gdbarch_get_longjmp_target (@var{gdbarch})
@findex gdbarch_get_longjmp_target
This function determines the target PC address that @code{longjmp} will jump to,
assuming that we have just stopped at a longjmp breakpoint. It takes a
@code{CORE_ADDR *} as argument, and stores the target PC value through this
pointer. It examines the current state of the machine as needed.
@item I386_USE_GENERIC_WATCHPOINTS
An x86-based machine can define this to use the generic x86 watchpoint
support; see @ref{Algorithms, I386_USE_GENERIC_WATCHPOINTS}.
