## There is some bad quoting interaction between lit's internal shell, which is
## implemented in Python, and the Cygwin implementations of the Unix utilities.
## Avoid running these tests on Windows for now by requiring a real shell.

# REQUIRES: shell

# REQUIRES: x86

# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %p/Inputs/shared.s -o %t2.o
# RUN: ld.lld -shared %t2.o -soname shared -o %t2.so
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t

## Check exporting only one symbol.
# RUN: echo "{ foo1; };" > %t.list
# RUN: ld.lld --dynamic-list %t.list %t %t2.so -o %t.exe
# RUN: llvm-readobj -dyn-symbols %t.exe | FileCheck %s

## And now using quoted strings (the output is the same since it does
## use any wildcard character).
# RUN: echo "{ \"foo1\"; };" > %t.list
# RUN: ld.lld --dynamic-list %t.list %t %t2.so -o %t.exe
# RUN: llvm-readobj -dyn-symbols %t.exe | FileCheck %s

## And now using --export-dynamic-symbol.
# RUN: ld.lld --export-dynamic-symbol foo1 %t %t2.so -o %t.exe
# RUN: llvm-readobj -dyn-symbols %t.exe | FileCheck %s
# RUN: ld.lld --export-dynamic-symbol=foo1 %t %t2.so -o %t.exe
