No it wasn't:


          for (regno = FIRST_ARM_FP_REGNUM;                             \
               regno <= LAST_ARM_FP_REGNUM; regno++)                    \
            if (regs_ever_live[regno] && ! call_used_regs[regno])       \
              offset += 12;                                             \

This code is entirely missing from the new version.

Also, I can't find this patch on gcc-patches.  When was it posted?
