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.
