/* N O T E S
This file 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
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.
