[Qemu-devel] [Bug 1577841] [NEW] target-mips/helper.c:542: bad sizeof ?

[dcb]

Public bug reported:

Recent versions of gcc say this:

qemu/target-mips/helper.c:542:9: warning: ‘memset’ used with length
equal to number of elements without multiplication by element size
[-Wmemset-elt-size]

Source code is

   memset(env->CP0_WatchLo, 0, sizeof(*env->CP0_WatchLo));

Maybe better code

   memset(env->CP0_WatchLo, 0, 8 * sizeof(target_ulong));

** Affects: qemu
     Importance: Undecided
         Status: New
