As reported, libgnat-12.so gets PT_GNU_STACK RWE, which means it doesn't work in some SELinux configurations. This is caused by the a-nbnbig.o file, which is a ghost unit and since r12-5670 the FE emits an object file for it, but exits before compile_file has a chance to finalize it e.g. with targetm.asm_out.file_end () that emits the .note.GNU-stack section on various linux targets. Fixed by not existing but instead returning early to the caller. 2022-01-14 Andrew Pinski <apinski@marvell.com> PR ada/104027 * gnat1drv.adb (Gnat1drv): After Back_End.Gen_Or_Update_Object_File goto End_Of_Program.
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.
