A testcase

I got

address@hidden cref]$ make
gcc -fPIC   -c -o x.o x.c
gcc -fPIC   -c -o y.o y.c
./ld -shared -o liby.so y.o
./ld --cref -shared -o libx1.so x.o -L. \
        --as-needed -ly --no-as-needed

Cross Reference Table

Symbol                                            File
_DYNAMIC                                          x.o
_GLOBAL_OFFSET_TABLE_                             x.o
__bss_start                                       ./liby.so
_edata                                            ./liby.so
_end                                              ./liby.so
_start                                            x.o
./ld: symbol `bar' missing from main hash table
bar                                               ./liby.so
./ld --cref -shared -o libx2.so x.o -L. -ly

Cross Reference Table

Symbol                                            File
_DYNAMIC                                          x.o
_GLOBAL_OFFSET_TABLE_                             x.o
__bss_start                                       ./liby.so
_edata                                            ./liby.so
_end                                              ./liby.so
_start                                            x.o
address@hidden cref]$

The error is

./ld: symbol `bar' missing from main hash table

since bar has been freed because liby.so isn't needed.
