# Regression test based on https://github.com/llvm/llvm-project/issues/54386
|
|
# Test that that linker synthetic functions such as __wasm_tls_init and
|
|
# __wasm_apply_global_tls_relocs can be created successfully in programs
|
|
# that don't reference __tls_base or __wasm_tls_init. These function both
|
|
# reference __tls_base which need to be marks as alive if they are generated.
|
|
|
|
# This is very basic TLS-using program that doesn't reference any of the
|
|
# linker-generated symbols.
