23 This version of fetch_core_registers() is used by most systems that
24 implement /proc. For these systems, the general registers are laid out
25 the same way in both the core file and the gregset_p structure. The
26 current exception to this is Irix-4.*, where the gregset_p structure is
27 split up into two pieces in the core file.
29 The general register and floating point register sets are manipulated by
30 separate ioctl's. This file makes the assumption that if FP0_REGNUM is
31 defined, then support for the floating point register set is desired,
32 regardless of whether or not the actual target has floating point hardware.

62 Read the values of either the general register set (WHICH equals 0)
63 or the floating point register set (WHICH equals 2) from the core
64 file data (pointed to by CORE_REG_SECT), and update gdb's idea of
65 their current values. The CORE_REG_SIZE parameter is ignored.
