13629
        (LEGITIMATE_PIC_OPERAND_P): Don't normally accept anything that
13630
        contains a SYMBOL_REF.  Relax this constraint during reload, since
13631

13632
        valid memory address, to control what insns need reloading.

        (nonimmediate_src_operand): Similar, for nonimmediate_operands.
13642

13645
        * m68k.md (many patterns): Rewrite common SImode, HImode, and
13646
        QImode insns to accept *_src_operand instead of *_operand where
13647
        pc-relative operands can fit.  For example, a pc-relative operand
13648
        can be used as a memory source operand for addsi3, but not as a
13649
        memory destination.
13650

17676
        (cpp_get_token): Break out string parsing code to
17677
        parse_string.  Use skip_comment for CHILL comments too.  Use
17678
        copy_comment for put_out_comments instead of dinking with
17679
        marks.  Remove stale code.  Don't call output_line_command
17680
        unless it's necessary.
17681
 
17682
        * cpplib.h (parse_marker): Removed.
17683
        (struct cpp_buffer): Line_base is now an unsigned char *; add
17684
        `mark' [long], remove `marks' [struct parse_marker *].
17685
        (parse_set_mark, parse_clear_mark, parse_goto_mark): Update

17744
        pending block.  Use head and tail pointers so we don't ever

17757
        dir is dropped from the include path because it doesn't
17758
        exist.  Fix memory leak: this function is not supposed to copy
17759

17774
        opts->verbose, print a notice when a duplicate dir is detected
17775
        and dropped from the include path.
17776
        (finclude): Fix excessive cleverness in setting
17777
        fp->system_header_p.
17778
        (actual_directory): Set x->sysp from
17779
        CPP_BUFFER (pfile)->system_header_p so that one system header
17780
        may include another with "".
17781
        (deps_output): Fix double adjustment of deps_size which would
17782
