+/* 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). */
