8290 "T" field selectors create DLT relative fixups for accessing
8291 globals and statics in PIC code; each DLT relative fixup creates
8292 an entry in the DLT table. The entries contain the address of
8293 the final target (eg accessing "foo" would create a DLT entry
8294 with the address of "foo").
8296 Unfortunately, the HP linker doesn't take into account any addend
8297 when generating the DLT; so accessing $LIT$+8 puts the address of
8298 $LIT$ into the DLT rather than the address of $LIT$+8.
8300 The end result is we can't perform relocation symbol reductions for
8301 any fixup which creates entries in the DLT (eg they use "T" field

8354 the start of the section. Additionally, the linker has no choice
8355 but to manipulate the addends when coalescing input sections for
8356 "ld -r". Since an LR% field selector is defined to round the
8357 addend, we can't change the addend without risking that a LR% and

8371 and the last address loses because rounding the addend to 8k

8374 In cases where the LR% expression is identical to the RR% one we
8375 will never have a problem, but is so happens that gcc rounds
8376 addends involved in LR% field selectors to work around a HP
8377 linker bug. ie. We often have addresses like the last case
