Introduce a couple of new CET intrinsics for reading and updating a shadow stack pointer (_get_ssp and _inc_ssp). They replace the existing _rdssp[d|q] and _incssp[d|q] instrinsics. PR target/84239 * gcc/config/i386/cetintrin.h: Remove _rdssp[d|q] and add _get_ssp intrinsics. Remove argument from __builtin_ia32_rdssp[d|q]. * gcc/config/i386/i386-builtin-types.def: Add UINT_FTYPE_VOID. * gcc/config/i386/i386-builtin.def: Remove argument from __builtin_ia32_rdssp[d|q]. * gcc/config/i386/i386.c: Use UINT_FTYPE_VOID. Use ix86_expand_special_args_builtin for _rdssp[d|q]. * gcc/config/i386/i386.md: Remove argument from rdssp[si|di] insn. Clear register before usage. * doc/extend.texi: Remove argument from __builtin_ia32_rdssp[d|q]. Add documentation for new _get_ssp and _inc_ssp intrinsics. * testsuite/gcc.target/i386/cet-intrin-3.c: Use new _get_ssp and _inc_ssp intrinsics. * testsuite/gcc.target/i386/cet-intrin-4.c: Likewise. * testsuite/gcc.target/i386/cet-rdssp-1.c: Remove argument from __builtin_ia32_rdssp[d|q]. * libgcc/config/i386/shadow-stack-unwind.hi (_Unwind_Frames_Extra): Use new _get_ssp and _inc_ssp intrinsics.

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.
