325 | ADDR[24|14] : fields that hold addresses in branch and cond | |
326 | branches. These represent [26|16] bit addresses. | |
327 | The low order 2 bits are preserved. | |
328 | REL[24|14] : branches relative to the Instruction Address | |
329 | register. These represent [26|16] bit addresses, | |
330 | as before. The instruction field will be zero, and | |
331 | the address of the SYM will be inserted at link time. | |
332 | TOCREL16 : 16 bit displacement field referring to a slot in | |
333 | toc. | |
334 | TOCREL14 : 16 bit displacement field, similar to REL14 or ADDR14. | |
335 | ADDR32NB : 32 bit address relative to the virtual origin. | |
336 | (On the alpha, this is always a linker generated thunk) | |
337 | (i.e. 32bit addr relative to the image base) | |
338 | SECREL : The value is relative to the start of the section | |
339 | containing the symbol. | |
340 | SECTION : access to the header containing the item. Supports the | |
341 | codeview debugger. | |
