AM		 8424
8425 If a symbol is reduced to a section symbol, the assembler will
8426 adjust the addend unless the symbol happens to reside right at
8427 the start of the section. Additionally, the linker has no choice
8428 but to manipulate the addends when coalescing input sections for
8429 "ld -r". Since an LR% field selector is defined to round the
8430 addend, we can't change the addend without risking that a LR% and
8431 it's corresponding (possible multiple) RR% field will no longer
8432 sum to the right value.
8433
8434 eg. Suppose we have
8435 . ldil LR%foo+0,%r21
8436 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8437 . ldw RR%foo+4(%r21),%r25
8438
8439 If foo is at address 4092 (decimal) in section `sect', then after
8440 reducing to the section symbol we get
8441 . LR%sect+4092 == (L%sect)+0
8442 . RR%sect+4092 == (R%sect)+4092
8443 . RR%sect+4096 == (R%sect)-4096
8444 and the last address loses because rounding the addend to 8k
0234cb7c 8445 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8446
8447 In cases where the LR% expression is identical to the RR% one we
8448 will never have a problem, but is so happens that gcc rounds
8449 addends involved in LR% field selectors to work around a HP
8450 linker bug. ie. We often have addresses like the last case
1cd1c99b
AM		 8451 above where the LR% expression is offset from the RR% one. */
