[Qemu-devel] [PATCH v3 00/16] tcg: tidy the type of code_ptr

[Richard Henderson]

Changes v2-v3: 
  * Make more use, where appropriate, of normal pointer arithmetic under
    the new type.  In particular, if the target previously computed
  
        (label - code_ptr) >> 2
  
    using byte arithmetic, we can now arrange for this to be just

        label - code_ptr
  
    with the shift added by the compiler.  Given that technically a right
    shift of a negative value is implementation defined (may the death of
    catering to one's compliment machine come soon), having the compiler do
    this is going to eliminate one more stupid warning from some sanitizer.
  
  * Finish conversion of all tcg backends.
