When the doubly-linked list tests were introduced, the tests were printing the content of the list forward and backward. However, this printing is not needed outside of debugging, and confuses people because the output is not only composed of PASS: lines. This patch disables the printing of the list content by default. If one wants to re-enable it for debugging, he can set the macro DUMP_LIST to 1. libiberty/ChangeLog: * testsuite/test-doubly-linked-list.c: disable debug logging on stdout.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
