1919 into the shared library. However, if we are linking with
1920 -Bsymbolic, we do not need to copy a reloc against a
1921 global symbol which is defined in an object we are
1922 including in the link (i.e., DEF_REGULAR is set). At
1923 this point we have not seen all the input files, so it is
1924 possible that DEF_REGULAR is not set now but will be set
1925 later (it is never cleared). In case of a weak definition,
1926 DEF_REGULAR may be cleared later by a strong definition in
1927 a shared library. We account for that possibility below by
1928 storing information in the relocs_copied field of the hash
1929 table entry. A similar situation occurs when creating
1930 shared libraries and symbol visibility changes render the
1931 symbol local.
1932
1933 If on the other hand, we are creating an executable, we
1934 may need to keep relocations for symbols satisfied by a
1935 dynamic library if we manage to avoid copy relocs for the
1936 symbol. */
