8348 | |
8349 | If a symbol is reduced to a section symbol, the assembler will | |
8350 | adjust the addend unless the symbol happens to reside right at | |
8351 | the start of the section. Additionally, the linker has no choice | |
8352 | but to manipulate the addends when coalescing input sections for | |
8353 | "ld -r". Since an LR% field selector is defined to round the | |
8354 | addend, we can't change the addend without risking that a LR% and | |
8355 | it's corresponding (possible multiple) RR% field will no longer | |
8356 | sum to the right value. | |
8357 | ||
8358 | eg. Suppose we have | |
8359 | . ldil LR%foo+0,%r21 | |
8360 | . ldw RR%foo+0(%r21),%r26 | |
25a8b250 AM |
8361 | . ldw RR%foo+4(%r21),%r25 |
8362 | ||
8363 | If foo is at address 4092 (decimal) in section `sect', then after | |
8364 | reducing to the section symbol we get | |
8365 | . LR%sect+4092 == (L%sect)+0 | |
8366 | . RR%sect+4092 == (R%sect)+4092 | |
8367 | . RR%sect+4096 == (R%sect)-4096 | |
8368 | and the last address loses because rounding the addend to 8k | |
0234cb7c | 8369 | multiples takes us up to 8192 with an offset of -4096. |
25a8b250 AM |
8370 | |
8371 | In cases where the LR% expression is identical to the RR% one we | |
8372 | will never have a problem, but is so happens that gcc rounds | |
8373 | addends involved in LR% field selectors to work around a HP | |
8374 | linker bug. ie. We often have addresses like the last case | |
