8274 "T" field selectors create DLT relative fixups for accessing
8275 globals and statics in PIC code; each DLT relative fixup creates
8276 an entry in the DLT table. The entries contain the address of
8277 the final target (eg accessing "foo" would create a DLT entry
8278 with the address of "foo").
8280 Unfortunately, the HP linker doesn't take into account any addend
8281 when generating the DLT; so accessing $LIT$+8 puts the address of
8282 $LIT$ into the DLT rather than the address of $LIT$+8.
8284 The end result is we can't perform relocation symbol reductions for
8285 any fixup which creates entries in the DLT (eg they use "T" field

8334 the start of the section. Additionally, the linker has no choice
8335 but to manipulate the addends when coalescing input sections for
8336 "ld -r". Since an LR% field selector is defined to round the
8337 addend, we can't change the addend without risking that a LR% and

8351 and the last address loses because rounding the addend to 8k
8352 mutiples takes us up to 8192 with an offset of -4096.
8354 In cases where the LR% expression is identical to the RR% one we
8355 will never have a problem, but is so happens that gcc rounds
8356 addends involved in LR% field selectors to work around a HP
8357 linker bug. ie. We often have addresses like the last case
