AM		 8446
8447 If a symbol is reduced to a section symbol, the assembler will
8448 adjust the addend unless the symbol happens to reside right at
8449 the start of the section. Additionally, the linker has no choice
8450 but to manipulate the addends when coalescing input sections for
8451 "ld -r". Since an LR% field selector is defined to round the
8452 addend, we can't change the addend without risking that a LR% and
8453 it's corresponding (possible multiple) RR% field will no longer
8454 sum to the right value.
8455
8456 eg. Suppose we have
8457 . ldil LR%foo+0,%r21
8458 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8459 . ldw RR%foo+4(%r21),%r25
8460
8461 If foo is at address 4092 (decimal) in section `sect', then after
8462 reducing to the section symbol we get
8463 . LR%sect+4092 == (L%sect)+0
8464 . RR%sect+4092 == (R%sect)+4092
8465 . RR%sect+4096 == (R%sect)-4096
8466 and the last address loses because rounding the addend to 8k
0234cb7c 8467 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8468
8469 In cases where the LR% expression is identical to the RR% one we
8470 will never have a problem, but is so happens that gcc rounds
8471 addends involved in LR% field selectors to work around a HP
8472 linker bug. ie. We often have addresses like the last case
1cd1c99b
AM		 8473 above where the LR% expression is offset from the RR% one. */
