rtl.texi (RTX_FRAME_RELATED_P): Add documentation.
d Thu Mar 25 14:04:54 EST 1999 Andrew MacLeod <amacleod@cygnus.com> * rtl.texi (RTX_FRAME_RELATED_P): Add documentation. * rtl.h (struct rtx_def): Update comment for frame_related field. (set_unique_reg_note): Declare prototype. * dwarf2out.c (dwarf2out_frame_debug_expr): Split out from 'dwarf2out_frame_debug' to handle only expressions, and process component parts of a PARALLEL expression. (dwarf2out_frame_debug): Process insns only, and call new function 'dwarf2out_frame_debug_expr' for patterns. * emit-rtl.c (set_unique_reg_note): New function to add a reg note, but if there is an existingone, deletes it first. * expmed.c (expand_mult, expand_divmod): Use set_unique_reg_note. * optabs.c (add_equal_note, expand_binop): Use set_unique_reg_note. (emit_no_conflict_block, emit_libcall_block): Use set_unique_reg_note. (expand_fix): Use set_unique_reg_note. From-SVN: r25979
