When GDB is configured and compiled, various macros are defined or
left undefined, to control compilation when the host and target systems
are the same. These macros should be defined (or left undefined) in
If defined, then gdb will include support for the `attach' and
Define this if the native-dependent code will provide its own
routines `fetch_inferior_registers' and `store_inferior_registers'
in `HOST-nat.c'. If this symbol is *not* defined, and
`infptrace.c' is included in this configuration, the default
routines in `infptrace.c' are used for these functions.
For most machines, this is a target-dependent parameter. On the
DECstation and the Iris, this is a native-dependent parameter,
since <setjmp.h> is needed to define it.
This macro determines the target PC address that longjmp() will
jump to, assuming that we have just stopped at a longjmp
breakpoint. It takes a CORE_ADDR * as argument, and stores the
target PC value through this pointer. It examines the current
state of the machine as needed.
Defines the format for the name of a `/proc' device. Should be
defined in `nm.h' *only* in order to override the default
definition in `procfs.c'.
The type of the third argument to the `ptrace' system call, if it
exists and is different from `int'.
Defines the offset of the registers in the "u area"; Note: Host..
This determines whether small routines in `*-tdep.c', which
translate register values between GDB's internal representation
and the /proc representation, are compiled.
This is the offset of the registers in the upage. It need only be
defined if the generic ptrace register access routines in
`infptrace.c' are being used (that is, `infptrace.c' is configured
in, and `FETCH_INFERIOR_REGISTERS' is not defined). If the
default value from `infptrace.c' is good enough, leave it
The default value means that u.u_ar0 *points to* the location of
the registers. I'm guessing that `#define U_REGS_OFFSET 0' means
that u.u_ar0 *is* the location of the registers.
