The following fixes the issue of ignoring side-effects on memory from overloaded global new/delete operators by not marking them as effectively 'const' apart from other explicitely specified side-effects. This will cause FAIL: g++.dg/warn/Warray-bounds-16.C -std=gnu++1? (test for excess errors) because we now no longer statically see the initialization loop never executes because the call to operator new can now clobber 'a.m'. This seems to be an issue with the warning code and/or ranger so I'm leaving this FAIL to be addressed as followup. 2021-10-11 Richard Biener <rguenther@suse.de> PR middle-end/101480 * gimple.c (gimple_call_fnspec): Do not mark operator new/delete as const. * g++.dg/torture/pr10148.C: 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.
