+
+     If a symbol is reduced to a section symbol, the assembler will
+     adjust the addend unless the symbol happens to reside right at
+     the start of the section.  Additionally, the linker has no choice
+     but to manipulate the addends when coalescing input sections for
+     "ld -r".  Since an LR% field selector is defined to round the
+     addend, we can't change the addend without risking that a LR% and
+     it's corresponding (possible multiple) RR% field will no longer
+     sum to the right value.
+
+     eg. Suppose we have
+     .         ldil    LR%foo+0,%r21
+     .         ldw     RR%foo+0(%r21),%r26
+     .         ldw     RR%foo+4(%r21),%r25
+
+     If foo is at address 4092 (decimal) in section `sect', then after
+     reducing to the section symbol we get
+     .                 LR%sect+4092 == (L%sect)+0
+     .                 RR%sect+4092 == (R%sect)+4092
+     .                 RR%sect+4096 == (R%sect)-4096
+     and the last address loses because rounding the addend to 8k
+     multiples takes us up to 8192 with an offset of -4096.
+
+     In cases where the LR% expression is identical to the RR% one we
+     will never have a problem, but is so happens that gcc rounds
+     addends involved in LR% field selectors to work around a HP
+     linker bug.  ie. We often have addresses like the last case
+     above where the LR% expression is offset from the RR% one.  */
