        F_RELFLG        relocation info stripped from file
28
        F_EXEC          file is executable (no unresolved external references)
29
        F_LNNO          line numbers stripped from file
30
        F_LSYMS         local symbols stripped from file
31
        F_INTERWORK     file supports switching between ARM and Thumb instruction sets
32
        F_INTERWORK_SET the F_INTERWORK bit is valid
33
        F_APCS_FLOAT    code passes float arguments in float registers
34
        F_PIC           code is reentrant/position-independent
35
        F_AR32WR        file has byte ordering of an AR32WR machine (e.g. vax)
36
        F_APCS_26       file uses 26 bit ARM Procedure Calling Standard
37
        F_APCS_SET      the F_APCS_26, F_APCS_FLOAT and F_PIC bits have been initialised
38
        F_SOFT_FLOAT    code does not use floating point instructions.  */
