# RUN: ld.lld --dynamic-list %t.list %t.o %t2.so -o %t
# RUN: llvm-nm -D %t | FileCheck %s --implicit-check-not=foo

## And now using quoted strings (the output is the same since it does not
## use any wildcard character).
# RUN: echo '{ "foo1"; };' > %t.list
# RUN: ld.lld --dynamic-list %t.list %t.o %t2.so -o %t2
# RUN: cmp %t %t2

## And now using --export-dynamic-symbol.
# RUN: ld.lld --export-dynamic-symbol foo1 %t.o %t2.so -o %t2
# RUN: cmp %t %t2
# RUN: ld.lld --export-dynamic-symbol=foo1 %t.o %t2.so -o %t2
# RUN: cmp %t %t2

# CHECK: foo1

## Now export all the foo1, foo2, and foo31 symbols
# RUN: echo "{ foo1; foo2; foo31; };" > %t.list

## --export-dynamic is similar to --dynamic-list with '{ * }'

# RUN: ld.lld --dynamic-list %t.list --export-dynamic %t.o %t2.so -o %t
# RUN: llvm-nm -D %t | FileCheck --check-prefix=CHECK3 %s --implicit-check-not=foo

## The same with --export-dynamic-symbol.
# RUN: ld.lld --export-dynamic-symbol=foo2 --export-dynamic %t.o %t2.so -o %t2
# RUN: cmp %t %t2
