8284 "T" field selectors create DLT relative fixups for accessing
8285 globals and statics in PIC code; each DLT relative fixup creates
8286 an entry in the DLT table. The entries contain the address of
8287 the final target (eg accessing "foo" would create a DLT entry
8288 with the address of "foo").
8290 Unfortunately, the HP linker doesn't take into account any addend
8291 when generating the DLT; so accessing $LIT$+8 puts the address of
8292 $LIT$ into the DLT rather than the address of $LIT$+8.
8294 The end result is we can't perform relocation symbol reductions for
8295 any fixup which creates entries in the DLT (eg they use "T" field

8348 the start of the section. Additionally, the linker has no choice
8349 but to manipulate the addends when coalescing input sections for
8350 "ld -r". Since an LR% field selector is defined to round the
8351 addend, we can't change the addend without risking that a LR% and

8365 and the last address loses because rounding the addend to 8k

8368 In cases where the LR% expression is identical to the RR% one we
8369 will never have a problem, but is so happens that gcc rounds
8370 addends involved in LR% field selectors to work around a HP
