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").
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.
8310 The end result is we can't perform relocation symbol reductions for
8311 any fixup which creates entries in the DLT (eg they use "T" field

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

8381 and the last address loses because rounding the addend to 8k

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
