603 # built without use of C library headers and do not have any global
604 # state so can safely be linked statically into any executable or
605 # shared library requiring them; these functions are in libgcc.a.

607 # library headers to build and it may not be safe to have more than

612 # to avoid use of libgcc_s and libgcc_eh in building glibc. Where any
613 # glibc functionality (in particular, thread cancellation) requires
614 # exception handling, this is implemented through dlopen of libgcc_s
615 # to avoid unnecessary dependencies on libgcc_s by programs not using
616 # that functionality; executables built with glibc do not use
617 # exception handling other than through thread cancellation.
619 # Undefined references to functions from libgcc_eh or libgcc_s may
620 # arise for code built with -fexceptions. In the case of statically
621 # linked programs installed by glibc, unwinding will never actually
622 # occur at runtime and the use of elf/static-stubs.c to resolve these
623 # references is safe. In the case of statically linked test programs
624 # and test programs built with -fexceptions, unwinding may occur in
625 # some cases and it is preferable to link with libgcc_eh or libgcc_s
626 # so that the testing is as similar as possible to how programs will
627 # be built with the installed glibc.
