601 | # How to link against libgcc. Some libgcc functions, such as those |
602 | # for "long long" arithmetic or software floating point, can always be | |
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. | |
606 | # Other functions, relating to exception handling, may require C | |
607 | # library headers to build and it may not be safe to have more than | |
608 | # one copy of them in a process; these functions are only in | |
609 | # libgcc_s.so and libgcc_eh.a. | |
610 | # | |
611 | # To avoid circular dependencies when bootstrapping, it is desirable | |
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. | |
618 | # | |
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. | |
