Merge lp:~ramana/gcc-linaro/46-vfp-wb-addressing into lp:gcc-linaro/4.6

[Ramana Radhakrishnan]

This attempts to fix up ivopts to not just use the presence of HAVE_POST/PRE_INC/DEC to decide whether to mark an ivopt candidate as a candidate for pre increment vs post increment.

For the testcase below before the patch we generate
 void foo (float *x , float *y, float *z, float *m, int l)
   {
      int i;
      for (i = 0; i < l ; i++)
      {
        z[i] = x[i] * y[i] + m[i];
      }
   }

 sub r0, r0, #4
 sub r1, r1, #4
 sub r3, r3, #4
 add ip, r2, ip, asl #2
.L3:
 add r3, r3, #4
 add r0, r0, #4
 flds s15, [r3, #0]
 flds s13, [r0, #0]
 add r1, r1, #4
 flds s14, [r1, #0]
 fmacs s15, s13, s14
 mov r4, r3
 fstmias r2!, {s15}
 cmp r2, ip
 bne .L3
.L1:
 ldmfd sp!, {r4}
 bx lr

and after we generate :

foo:
 @ args = 4, pretend = 0, frame = 0
 @ frame_needed = 0, uses_anonymous_args = 0
 @ link register save eliminated.
 ldr ip, [sp, #0]
 cmp ip, #0
 bxle lr
 add ip, r0, ip, asl #2
.L3:
 fldmias r0!, {s13}
 fldmias r1!, {s14}
 fldmias r3!, {s15}
 fmacs s15, s13, s14
 cmp r0, ip
 fstmias r2!, {s15}
 bne .L3
 bx lr

Finally fixed up for the last changes for disabling PRE_INC instead of accidentally disabling PRE_DEC.

[Ramana Radhakrishnan (ramana)]

Currently only for benchmarking and testing.
