8356 "T" field selectors create DLT relative fixups for accessing
8357 globals and statics in PIC code; each DLT relative fixup creates
8358 an entry in the DLT table. The entries contain the address of
8359 the final target (eg accessing "foo" would create a DLT entry
8360 with the address of "foo").
8362 Unfortunately, the HP linker doesn't take into account any addend
8363 when generating the DLT; so accessing $LIT$+8 puts the address of
8364 $LIT$ into the DLT rather than the address of $LIT$+8.
8366 The end result is we can't perform relocation symbol reductions for
8367 any fixup which creates entries in the DLT (eg they use "T" field

8447 the start of the section. Additionally, the linker has no choice
8448 but to manipulate the addends when coalescing input sections for
8449 "ld -r". Since an LR% field selector is defined to round the

8467 In cases where the LR% expression is identical to the RR% one we
