Remove dwarf_decode_lines argumewant_line_info
Hi,
dwarf_decode_lines is called in two functions,
dwarf2_build_include_psymtabs and handle_DW_AT_stmt_list, in which, 1
is passed to argument 'want_line_info' and 'want_line_info' is a
conditional variable in dwarf_decode_lines. We can simplify it by
removing 'want_line_info' and propagating the constant 1 into
dwarf_decode_lines. This is what this patch does. This patch also
remove one line comment about WANT_LINE_INFO in
handle_DW_AT_stmt_list, as handle_DW_AT_stmt_list doesn't have such
argument.
gdb:
2014-08-28 Yao Qi <yao@codesourcery.com>
* dwarf2read.c (dwarf_decode_lines): Update declaration.
(handle_DW_AT_stmt_list): Remove comment about WANT_LINE_INFO.
(dwarf_decode_lines): Remove argument
want_line_info. Remove condition check on want_line_info.
Callers update.
