8383 "T" field selectors create DLT relative fixups for accessing
8384 globals and statics in PIC code; each DLT relative fixup creates
8385 an entry in the DLT table. The entries contain the address of
8386 the final target (eg accessing "foo" would create a DLT entry
8387 with the address of "foo").
8388
8389 Unfortunately, the HP linker doesn't take into account any addend
8390 when generating the DLT; so accessing $LIT$+8 puts the address of
8391 $LIT$ into the DLT rather than the address of $LIT$+8.
8392
8393 The end result is we can't perform relocation symbol reductions for
8394 any fixup which creates entries in the DLT (eg they use "T" field
8395 selectors).

8463 If a symbol is reduced to a section symbol, the assembler will
8464 adjust the addend unless the symbol happens to reside right at
8465 the start of the section. Additionally, the linker has no choice
8466 but to manipulate the addends when coalescing input sections for
8467 "ld -r". Since an LR% field selector is defined to round the
8468 addend, we can't change the addend without risking that a LR% and
8469 it's corresponding (possible multiple) RR% field will no longer
8470 sum to the right value.
8471
8472 eg. Suppose we have
8473 . ldil LR%foo+0,%r21
8474 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8475 . ldw RR%foo+4(%r21),%r25
8476
8477 If foo is at address 4092 (decimal) in section `sect', then after
8478 reducing to the section symbol we get
8479 . LR%sect+4092 == (L%sect)+0
8480 . RR%sect+4092 == (R%sect)+4092
8481 . RR%sect+4096 == (R%sect)-4096
8482 and the last address loses because rounding the addend to 8k
0234cb7c 8483 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8484
8485 In cases where the LR% expression is identical to the RR% one we
8486 will never have a problem, but is so happens that gcc rounds
8487 addends involved in LR% field selectors to work around a HP
8488 linker bug. ie. We often have addresses like the last case
1cd1c99b
