c6d8db406c [Revise prev change -- this is how it's been running at Adobe, and it works
there.]

* sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
coprocessor status regs) when popping a frame.  This fixes
float exceptions that occur after calling inferior functions.

* sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Read and write the fsr (float status register) to/from the child
process along with the float regs.  Remove Peter Schauer's change
of May 24 '93, which has higher overhead and doesn't solve the
real problem (which was that FSR wasn't being set).

c369b6a32f * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Read and write the fsr (float status register) to/from the child
process.  This avoids random float exceptions when running under
GDB, and probably obsoletes Peter Schauer's change of May 24 '93
(which remains for safety).

199b2450f6 Change the stream argument to _filtered to GDB_FILE *.
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.

Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')

Replaced calls to fopen for output to gdb_fopen.

Added sufficient goo to utils.c and defs.h to make the above work.

The net effect is that stdio output functions are only directly used
in utils.c.  Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.

In the near future, GDB_FILE will stop being equivalant to FILE.

The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior.  The testsuite doesn't notice anything
like this, though.

Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code.  All output from commands
should go to a GDB_FILE.

Target-specific code can still use stdio directly to communicate with
targets.

1b71de8ea4 * sparc-nat.c (store_inferior_registers): Fill in all members of
inferior_fp_registers by reading them from the inferior before
	modifying and writing them back.
	Fixes unexplainable inferior FP exceptions after calls to the inferior
	or setting of floating point registers.
	* mips-tdep.c (mips_skip_prologue):  Skip move of argument register
	to register which is generated by gcc-2.4.
