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

-GLOBAL FUNCTION
-
- fetch_core_registers -- fetch current registers from core file data
-
-SYNOPSIS
-
- void fetch_core_registers (char *core_reg_sect, unsigned core_reg_size,
- int which, unsigned in reg_addr)
-
-DESCRIPTION
-
- Read the values of either the general register set (WHICH equals 0)
- or the floating point register set (WHICH equals 2) from the core
- file data (pointed to by CORE_REG_SECT), and update gdb's idea of
- their current values. The CORE_REG_SIZE parameter is ignored.
-
-NOTES
-
- Use the indicated sizes to validate the gregset and fpregset
- structures.
