I'm having trouble compiling the following code. I'm willing to bash on the
mips.md description some more, but can't see why this instance isn't
covered.

The missing pattern is:
	
	gcc -c test5.cc
	test5.cc: In function int foo (struct bar *, int):
	test5.cc:24: The following insn was not recognizable:
	(insn 32 31 33 (parallel[
	           (set (reg:DF 6)
	               (mem:SF (reg:SI 76)))
	           (clobber (reg:SI 24))
	       ] ) -1 (nil)
	   (nil))

but in mips.md, I have
	(define_insn "movdf"
	  [(set (match_operand:DF 0 "general_operand" "=f,f,m,f,*f,*y")
		(match_operand:DF 1 "general_operand" "f,m,f,F,*y,*f"))
	
and I don't understand why the pattern above isn't matched by
the arg. pair "f" & "m" (i.e. the second pattern). If anyone knows
what pattern *should* match this, I'll implement it.

The code causing this problem follows. This was on a decstation-3100
with the latest version. Note that the first use, passing the coerced
address to a function, doesn't cause the pattern miss, it's only the
second use that does. Any help appreciated.

----------------------------------------------------------------------
#include <stream.h>

typedef struct  {
    float *f;
    double *d;
    long *addr;
} bar;

int
foo(bar *b, int arg)
{
    extern oof(double x);

    oof( *((float*) b[arg].addr) ); 

    cout << *((float*) b[arg].addr);
}


----------------------------------------------------------------------
p.s. I'm also having trouble with missing this pattern. I think it's
related the previous case. Is this so?

(insn 69 68 70 (parallel[ 
           (set (reg:DF 6)
               (mem/s:SF (plus:SI (reg/v/u:SI 64)
                       (const_int 8))))
           (clobber (reg:SI 24))
       ] ) -1 (nil)
   (nil))
