-/* Macros for setting and testing a bit in a minimal symbol that
- marks it as Thumb function. The MSB of the minimal symbol's
- "info" field is used for this purpose. This field is already
- being used to store the symbol size, so the assumption is
- that the symbol size cannot exceed 2^31.
-
- COFF_MAKE_MSYMBOL_SPECIAL
- ELF_MAKE_MSYMBOL_SPECIAL tests whether the COFF or ELF symbol corresponds
- to a thumb function, and sets a "special" bit in a
- minimal symbol to indicate that it does
- MSYMBOL_SET_SPECIAL actually sets the "special" bit
- MSYMBOL_IS_SPECIAL tests the "special" bit in a minimal symbol
- MSYMBOL_SIZE returns the size of the minimal symbol, i.e.
- the "info" field with the "special" bit masked out
