380 | ADDR[64|32|16] : fields that hold addresses in data fields or the | |

382 | ADDR[24|14] : fields that hold addresses in branch and cond | |
383 | branches. These represent [26|16] bit addresses. | |
384 | The low order 2 bits are preserved. | |
385 | REL[24|14] : branches relative to the Instruction Address | |
386 | register. These represent [26|16] bit addresses, | |
387 | as before. The instruction field will be zero, and | |
388 | the address of the SYM will be inserted at link time. | |
389 | TOCREL16 : 16 bit displacement field referring to a slot in | |
390 | toc. | |
391 | TOCREL14 : 16 bit displacement field, similar to REL14 or ADDR14. | |
392 | ADDR32NB : 32 bit address relative to the virtual origin. | |
393 | (On the alpha, this is always a linker generated thunk) | |
394 | (i.e. 32bit addr relative to the image base) | |
395 | SECREL : The value is relative to the start of the section | |
396 | containing the symbol. | |
397 | SECTION : access to the header containing the item. Supports the | |
398 | codeview debugger. | |
