This patch suppresses a spurious warning coming from the GCC backend, on an aggregate that cannot be built in place and for which a temporary variable must be created. If the type of the aggregate is a packed boolean array, the generated code may appear to use an uninitialized value for a component of the array, when in fact the code simply sets a single bit of that array. 2018-10-09 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_aggr.adb (Expand_Array_Aggregate): If it is not possible to build in place an aggregate with component associations, set the Warnings_Off flag on the generated temporary, to prevent spurious warnings from the backend when compiling with the -Wuninitialized gcc flag. gcc/testsuite/ * gnat.dg/warn18.adb: New testcase.

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.
