 /* The following bits of code help with implementing debugging 32-bit
    code natively on AMD64.  The idea is to define two mappings between
    the register number as used by GDB and the register set used by the
    host to represent the general-purpose registers; one for 32-bit
    code and one for 64-bit code.  The mappings are specified by the
-   follwing variables and consist of an array of offsets within the
+   following variables and consist of an array of offsets within the
    register set indexed by register number, and the number of
    registers supported by the mapping.  We don't need mappings for the
    floating-point and SSE registers, since the difference between
-   64-bit and 32-bit variants are negligable.  The difference in the
+   64-bit and 32-bit variants are negligible.  The difference in the
    number of SSE registers is already handled by the target code.  */
