8390 but to manipulate the addends when coalescing input sections for
8391 "ld -r". Since an LR% field selector is defined to round the
8392 addend, we can't change the addend without risking that a LR% and
8393 it's corresponding (possible multiple) RR% field will no longer
8394 sum to the right value.
8395
8396 eg. Suppose we have
8397 . ldil LR%foo+0,%r21
8398 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8399 . ldw RR%foo+4(%r21),%r25
8400
8401 If foo is at address 4092 (decimal) in section `sect', then after
8402 reducing to the section symbol we get
8403 . LR%sect+4092 == (L%sect)+0
8404 . RR%sect+4092 == (R%sect)+4092
8405 . RR%sect+4096 == (R%sect)-4096
8406 and the last address loses because rounding the addend to 8k
0234cb7c 8407 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8408
8409 In cases where the LR% expression is identical to the RR% one we
8410 will never have a problem, but is so happens that gcc rounds
8411 addends involved in LR% field selectors to work around a HP
8412 linker bug. ie. We often have addresses like the last case
1cd1c99b
AM		 8413 above where the LR% expression is offset from the RR% one. */
