8292 "T" field selectors create DLT relative fixups for accessing
8293 globals and statics in PIC code; each DLT relative fixup creates
8294 an entry in the DLT table. The entries contain the address of
8295 the final target (eg accessing "foo" would create a DLT entry
8296 with the address of "foo").
8297
8298 Unfortunately, the HP linker doesn't take into account any addend
8299 when generating the DLT; so accessing $LIT$+8 puts the address of
8300 $LIT$ into the DLT rather than the address of $LIT$+8.
8301

8372 If a symbol is reduced to a section symbol, the assembler will
8373 adjust the addend unless the symbol happens to reside right at
8374 the start of the section. Additionally, the linker has no choice
8375 but to manipulate the addends when coalescing input sections for
8376 "ld -r". Since an LR% field selector is defined to round the
8377 addend, we can't change the addend without risking that a LR% and
8378 it's corresponding (possible multiple) RR% field will no longer
8379 sum to the right value.
8380
8381 eg. Suppose we have
8382 . ldil LR%foo+0,%r21
8383 . ldw RR%foo+0(%r21),%r26
25a8b250
AM		 8384 . ldw RR%foo+4(%r21),%r25
8385
8386 If foo is at address 4092 (decimal) in section `sect', then after
8387 reducing to the section symbol we get
8388 . LR%sect+4092 == (L%sect)+0
8389 . RR%sect+4092 == (R%sect)+4092
8390 . RR%sect+4096 == (R%sect)-4096
8391 and the last address loses because rounding the addend to 8k
0234cb7c 8392 multiples takes us up to 8192 with an offset of -4096.
25a8b250
AM		 8393
8394 In cases where the LR% expression is identical to the RR% one we
8395 will never have a problem, but is so happens that gcc rounds
8396 addends involved in LR% field selectors to work around a HP
8397 linker bug. ie. We often have addresses like the last case
1cd1c99b
