+/* The bit_fix was implemented to support machines that need variables
+   to be inserted in bitfields other than 1, 2 and 4 bytes.
+   Furthermore it gives us a possibility to mask in bits in the symbol
+   when it's fixed in the objectcode and check the symbols limits.
+
+   The or-mask is used to set the huffman bits in displacements for the
+   ns32k port.
+   The acbi, addqi, movqi, cmpqi instruction requires an assembler that
+   can handle bitfields.  Ie. handle an expression, evaluate it and insert
+   the result in some bitfield.  (eg: 5 bits in a short field of an opcode)
