lld/test/wasm/lto/pic-empty.s

   1 ; Test that LTO objects with no function can still be linked as shared
   2 ; libraries.
   3 ; We had a bug where the mutable-globals feature was not being added
   4 ; so the linker-generated import of `__stack_pointer` (which is currently
   5 ; mandatory for ; shared libraries) was generating a linker error.
   6 ; See https://github.com/llvm/llvm-project/issues/51681.
