Since ld is Intel CET enabled on Intel CET enabled host, dlopen fails on liblto_plugin.so if it isn't Intel CET enabled. Add GCC_CET_HOST_FLAGS to cet.m4, use it in libiberty and lto-plugin to always enable Intel CET in liblto_plugin.so on Intel CET enabled host. On Linux/x86 host, enable Intel CET by default if assembler and compiler support Intel CET so that the generated liblto_plugin.so can be used on both CET and non-CET machines. It is an error to disable Intel CET in liblto_plugin.so on Intel CET enabled host. config/ PR bootstrap/94739 * cet.m4 (GCC_CET_HOST_FLAGS): New. libiberty/ PR bootstrap/94739 * Makefile.in (COMPILE.c): Add @CET_HOST_FLAGS@.

README
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.
