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