/* 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 possibillity 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 an some bitfield. ( ex: 5 bits in a short field of a opcode)
