        F_LNNO          line numbers stripped from file

        F_LSYMS         local symbols stripped from file

        F_INTERWORK     file supports switching between ARM and Thumb instruction sets

        F_INTERWORK_SET the F_INTERWORK bit is valid

        F_APCS_FLOAT    code passes float arguments in float registers

        F_PIC           code is reentrant/position-independent

        F_AR32WR        file has byte ordering of an AR32WR machine (e.g. vax)

        F_APCS_26       file uses 26 bit ARM Procedure Calling Standard

        F_APCS_SET      the F_APCS_26, F_APCS_FLOAT and F_PIC bits have been initialised

        F_SOFT_FLOAT    code does not use floating point instructions.  */
