/* The following constants specify the sizes of the various data
structures that we have to create in order to build a bfd describing
an ILF object file. The final "+ 1" in the definitions of SIZEOF_IDATA6
and SIZEOF_IDATA7 below is to allow for the possibility that we might
need a padding byte in order to ensure 16 bit alignment for the section's
contents.
The value for SIZEOF_ILF_STRINGS is computed as follows:
There will be NUM_ILF_SECTIONS section symbols. Allow 9 characters
per symbol for their names (longest section name is .idata$2).
There will be two symbols for the imported value, one the symbol name
and one with _imp__ prefixed. Allowing for the terminating nul's this
is strlen (symbol_name) * 2 + 8.
The strings in the string table must start STRING__SIZE_SIZE bytes into
the table in order to for the string lookup code in coffgen/coffcode to
work. */
