AM		 8432
8433 If a symbol is reduced to a section symbol, the assembler will
8434 adjust the addend unless the symbol happens to reside right at
8435 the start of the section. Additionally, the linker has no choice
8436 but to manipulate the addends when coalescing input sections for
8437 "ld -r". Since an LR% field selector is defined to round the
8438 addend, we can't change the addend without risking that a LR% and
8439 it's corresponding (possible multiple) RR% field will no longer
8440 sum to the right value.
8441
8442 eg. Suppose we have
8443 . ldil LR%foo+0,%r21
8444 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8445 . ldw RR%foo+4(%r21),%r25
8446
8447 If foo is at address 4092 (decimal) in section `sect', then after
8448 reducing to the section symbol we get
8449 . LR%sect+4092 == (L%sect)+0
8450 . RR%sect+4092 == (R%sect)+4092
8451 . RR%sect+4096 == (R%sect)-4096
8452 and the last address loses because rounding the addend to 8k
0234cb7c 8453 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8454
8455 In cases where the LR% expression is identical to the RR% one we
8456 will never have a problem, but is so happens that gcc rounds
8457 addends involved in LR% field selectors to work around a HP
8458 linker bug. ie. We often have addresses like the last case
1cd1c99b
AM		 8459 above where the LR% expression is offset from the RR% one. */
