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

8361
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.
8365

8445 If a symbol is reduced to a section symbol, the assembler will
8446 adjust the addend unless the symbol happens to reside right at
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
8450 addend, we can't change the addend without risking that a LR% and
8451 it's corresponding (possible multiple) RR% field will no longer
8452 sum to the right value.
8453
8454 eg. Suppose we have
8455 . ldil LR%foo+0,%r21
8456 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8457 . ldw RR%foo+4(%r21),%r25
8458
8459 If foo is at address 4092 (decimal) in section `sect', then after
8460 reducing to the section symbol we get
8461 . LR%sect+4092 == (L%sect)+0
8462 . RR%sect+4092 == (R%sect)+4092
8463 . RR%sect+4096 == (R%sect)-4096
8464 and the last address loses because rounding the addend to 8k
0234cb7c 8465 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8466
8467 In cases where the LR% expression is identical to the RR% one we
8468 will never have a problem, but is so happens that gcc rounds
8469 addends involved in LR% field selectors to work around a HP
8470 linker bug. ie. We often have addresses like the last case
