* final.c (output_addr_const) [LABEL_REF]: Simplify.
[MINUS]: Enclose non-CONST_INTs in parentheses.
[default]: Try OUTPUT_ADDR_CONST_EXTRA.
* tm.texi (OUTPUT_ADDR_CONST_EXTRA): Document it.
* varasm.c (decode_rtx_const) [CONST]: If it's not something
PLUS or MINUS a CONST_INT, use the whole CONST with offset 0
instead of abort()ing.
* sh.c (output_pic_addr_const): Removed. Fixed all callers.
* sh.h (OUTPUT_ADDR_CONST_EXTRA): New. Handle the UNSPECs
formerly handled in output_pic_addr_const.
* sh.md (sym_label2reg, symPLT_label2reg): Enclose UNSPEC
operands of MINUS in CONSTs so that decode_rtx_const() will
accept them.
