8344 "T" field selectors create DLT relative fixups for accessing
8345 globals and statics in PIC code; each DLT relative fixup creates
8346 an entry in the DLT table. The entries contain the address of
8347 the final target (eg accessing "foo" would create a DLT entry
8348 with the address of "foo").
8349
8350 Unfortunately, the HP linker doesn't take into account any addend
8351 when generating the DLT; so accessing $LIT$+8 puts the address of
8352 $LIT$ into the DLT rather than the address of $LIT$+8.
8353

8406 If a symbol is reduced to a section symbol, the assembler will
8407 adjust the addend unless the symbol happens to reside right at
8408 the start of the section. Additionally, the linker has no choice
8409 but to manipulate the addends when coalescing input sections for
8410 "ld -r". Since an LR% field selector is defined to round the
8411 addend, we can't change the addend without risking that a LR% and
8412 it's corresponding (possible multiple) RR% field will no longer
8413 sum to the right value.
8414
8415 eg. Suppose we have
8416 . ldil LR%foo+0,%r21
8417 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8418 . ldw RR%foo+4(%r21),%r25
8419
8420 If foo is at address 4092 (decimal) in section `sect', then after
8421 reducing to the section symbol we get
8422 . LR%sect+4092 == (L%sect)+0
8423 . RR%sect+4092 == (R%sect)+4092
8424 . RR%sect+4096 == (R%sect)-4096
8425 and the last address loses because rounding the addend to 8k
8426 mutiples takes us up to 8192 with an offset of -4096.
8427
8428 In cases where the LR% expression is identical to the RR% one we
8429 will never have a problem, but is so happens that gcc rounds
8430 addends involved in LR% field selectors to work around a HP
8431 linker bug. ie. We often have addresses like the last case
