| 40 | /* The bit_fix was implemented to support machines that need variables | |
| 41 | to be inserted in bitfields other than 1, 2 and 4 bytes. | |
| 42 | Furthermore it gives us a possibillity to mask in bits in the symbol | |
| 43 | when it's fixed in the objectcode and check the symbols limits. | |
| 44 | ||
| 45 | The or-mask is used to set the huffman bits in displacements for the | |
| 46 | ns32k port. | |
| 47 | The acbi, addqi, movqi, cmpqi instruction requires an assembler that | |
| 48 | can handle bitfields. Ie handle an expression, evaluate it and insert | |
| 49 | the result in an some bitfield. ( ex: 5 bits in a short field of a opcode) | |
