8310 | "T" field selectors create DLT relative fixups for accessing | |
8311 | globals and statics in PIC code; each DLT relative fixup creates | |
8312 | an entry in the DLT table. The entries contain the address of | |
8313 | the final target (eg accessing "foo" would create a DLT entry | |
8314 | with the address of "foo"). | |
8315 | ||
8316 | Unfortunately, the HP linker doesn't take into account any addend | |
8317 | when generating the DLT; so accessing $LIT$+8 puts the address of | |
8318 | $LIT$ into the DLT rather than the address of $LIT$+8. | |
8319 | ||

8389 | |
8390 | If a symbol is reduced to a section symbol, the assembler will | |
8391 | adjust the addend unless the symbol happens to reside right at | |
8392 | the start of the section. Additionally, the linker has no choice | |
8393 | but to manipulate the addends when coalescing input sections for | |
8394 | "ld -r". Since an LR% field selector is defined to round the | |
8395 | addend, we can't change the addend without risking that a LR% and | |
8396 | it's corresponding (possible multiple) RR% field will no longer | |
8397 | sum to the right value. | |
8398 | ||
8399 | eg. Suppose we have | |
8400 | . ldil LR%foo+0,%r21 | |
8401 | . ldw RR%foo+0(%r21),%r26 | |
25a8b250 AM |
8402 | . ldw RR%foo+4(%r21),%r25 |
8403 | ||
8404 | If foo is at address 4092 (decimal) in section `sect', then after | |
8405 | reducing to the section symbol we get | |
8406 | . LR%sect+4092 == (L%sect)+0 | |
8407 | . RR%sect+4092 == (R%sect)+4092 | |
8408 | . RR%sect+4096 == (R%sect)-4096 | |
8409 | and the last address loses because rounding the addend to 8k | |
0234cb7c | 8410 | multiples takes us up to 8192 with an offset of -4096. |
25a8b250 AM |
8411 | |
8412 | In cases where the LR% expression is identical to the RR% one we | |
8413 | will never have a problem, but is so happens that gcc rounds | |
8414 | addends involved in LR% field selectors to work around a HP | |
8415 | linker bug. ie. We often have addresses like the last case | |
1cd1c99b AM |
8416 | above where the LR% expression is offset from the RR% one. */ |
