8345 "T" field selectors create DLT relative fixups for accessing
8346 globals and statics in PIC code; each DLT relative fixup creates
8347 an entry in the DLT table. The entries contain the address of
8348 the final target (eg accessing "foo" would create a DLT entry
8349 with the address of "foo").
8351 Unfortunately, the HP linker doesn't take into account any addend
8352 when generating the DLT; so accessing $LIT$+8 puts the address of
8353 $LIT$ into the DLT rather than the address of $LIT$+8.
8355 The end result is we can't perform relocation symbol reductions for
8356 any fixup which creates entries in the DLT (eg they use "T" field

8436 the start of the section. Additionally, the linker has no choice
8437 but to manipulate the addends when coalescing input sections for
8438 "ld -r". Since an LR% field selector is defined to round the

8453 and the last address loses because rounding the addend to 8k

8456 In cases where the LR% expression is identical to the RR% one we

8458 addends involved in LR% field selectors to work around a HP
