Problem summary

  • ****************************************************************
    * USERS AFFECTED: Metal-C and users of inline asm feature.     *
    ****************************************************************
    * PROBLEM DESCRIPTION: When the compiler uses the              *
    *                      assembly path (Metal-C and inline asm)  *
    *                      then the test under mask instruction    *
    *                      could haveits mask incorrectly emitted  *
    *                      into assembly output. This will only    *
    *                      happen when the compiler tries to emit  *
    *                      the Y form of the instruction (ie.      *
    *                      memory displacement is > 4k or          *
    *                      displacement is negative)               *
