This change refines VXWORKS_LIBGCC_SPEC wrt the inclusion of -lgcc_eh. Unless the compiler features support for dual sjlj and table based eh, libgcc_eh.a is available only with multilib variants for which we build a shared lib (mrtp on VxWorks). Rework logic to handle absence of libgcc_s for -mrtp -mcmodel=large, using a conditional expr kind of spec. The gthread support in libgcc_eh might resort to libgcc functions on some targets, e.g. cas synchronisation routines on aarch64. Arrange to append -lgcc also after -lgcc_eh in VXWORKS_LIBGCC_SPEC. 2022-10-09 Olivier Hainque <hainque@adacore.com> gcc/ * config/vxworks.h (VX_LGCC_EH_SO0, VX_LGCC_EH_SO1): New internal macros. (VXWORKS_LIBGCC_SPEC): Use them and document.
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.
