8300 | "T" field selectors create DLT relative fixups for accessing | |
8301 | globals and statics in PIC code; each DLT relative fixup creates | |
8302 | an entry in the DLT table. The entries contain the address of | |
8303 | the final target (eg accessing "foo" would create a DLT entry | |
8304 | with the address of "foo"). | |
8305 | ||
8306 | Unfortunately, the HP linker doesn't take into account any addend | |
8307 | when generating the DLT; so accessing $LIT$+8 puts the address of | |
8308 | $LIT$ into the DLT rather than the address of $LIT$+8. | |
8309 | ||

1cd1c99b AM |
8361 | |
8362 | If a symbol is reduced to a section symbol, the assembler will | |
8363 | adjust the addend unless the symbol happens to reside right at | |
8364 | the start of the section. Additionally, the linker has no choice | |
8365 | but to manipulate the addends when coalescing input sections for | |
8366 | "ld -r". Since an LR% field selector is defined to round the | |
8367 | addend, we can't change the addend without risking that a LR% and | |
8368 | it's corresponding (possible multiple) RR% field will no longer | |
8369 | sum to the right value. | |
8370 | ||
8371 | eg. Suppose we have | |
8372 | . ldil LR%foo+0,%r21 | |
8373 | . ldw RR%foo+0(%r21),%r26 | |
25a8b250 AM |
8374 | . ldw RR%foo+4(%r21),%r25 |
8375 | ||
8376 | If foo is at address 4092 (decimal) in section `sect', then after | |
8377 | reducing to the section symbol we get | |
8378 | . LR%sect+4092 == (L%sect)+0 | |
8379 | . RR%sect+4092 == (R%sect)+4092 | |
8380 | . RR%sect+4096 == (R%sect)-4096 | |
8381 | and the last address loses because rounding the addend to 8k | |
8382 | mutiples takes us up to 8192 with an offset of -4096. | |
8383 | ||
8384 | In cases where the LR% expression is identical to the RR% one we | |
8385 | will never have a problem, but is so happens that gcc rounds | |
8386 | addends involved in LR% field selectors to work around a HP | |
8387 | linker bug. ie. We often have addresses like the last case | |
1cd1c99b AM |
8388 | above where the LR% expression is offset from the RR% one. */ |
