# How to link against libgcc.  Some libgcc functions, such as those
# for "long long" arithmetic or software floating point, can always be
# built without use of C library headers and do not have any global
# state so can safely be linked statically into any executable or
# shared library requiring them; these functions are in libgcc.a.
# Other functions, relating to exception handling, may require C
# library headers to build and it may not be safe to have more than
# one copy of them in a process; these functions are only in
# libgcc_s.so and libgcc_eh.a.
#
# To avoid circular dependencies when bootstrapping, it is desirable
# to avoid use of libgcc_s and libgcc_eh in building glibc.  Where any
# glibc functionality (in particular, thread cancellation) requires
# exception handling, this is implemented through dlopen of libgcc_s
# to avoid unnecessary dependencies on libgcc_s by programs not using
# that functionality; executables built with glibc do not use
# exception handling other than through thread cancellation.
#
# Undefined references to functions from libgcc_eh or libgcc_s may
# arise for code built with -fexceptions.  In the case of statically
# linked programs installed by glibc, unwinding will never actually
# occur at runtime and the use of elf/static-stubs.c to resolve these
# references is safe.  In the case of statically linked test programs
# and test programs built with -fexceptions, unwinding may occur in
# some cases and it is preferable to link with libgcc_eh or libgcc_s
# so that the testing is as similar as possible to how programs will
# be built with the installed glibc.
#
# Some architectures have architecture-specific systems for exception
# handling that may involve undefined references to
# architecture-specific functions.  On those architectures,
# gnulib-arch and static-gnulib-arch may be defined in sysdeps
# makefiles to use additional libraries for linking executables and
