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