    • SYS_BITSTART_MASK_THRESHOLD

      public static final int SYS_BITSTART_MASK_THRESHOLD
      Threshold used to distinguish system-register bit-start masks.
      See Also:

    • CPSR_Aliases

      public static final String[] CPSR_Aliases
      CPSR/APSR aliases indexed by mask.

    • APSR_MASK

      public static final int APSR_MASK
      APSR alias mask.
      See Also:

    • APSR_nzcv_MASK

      public static final int APSR_nzcv_MASK
      APSR_nzcv alias mask.
      See Also:

    • SPSR_Aliases

      public static final String[] SPSR_Aliases

      Returns:
      register bank

    • getDescriptionEntryMap

      public Map<Integer,RegisterDescriptionEntry> getDescriptionEntryMap()
      Description copied from class: AbstractRegisterBank
      Get the full-register description entries by register index.
      Specified by:
      getDescriptionEntryMap in class AbstractRegisterBank
      Returns:
      a map of full registers: key=index, value=full register entry

    • getSpId

      public static long getSpId()
      Retrieve the standard ARM stack-pointer id.
      Returns:
      stack-pointer register id
