# REQUIRES: x86, aarch64
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux /dev/null -o %t.o
# RUN: ld.lld -o %t.so --script %s %t.o -shared
# RUN: llvm-readobj --symbols %t.so | FileCheck %s

## Test that the script creates a non absolute symbol with value
## 0 I.E., a symbol that refers to the load address.

# CHECK:      Symbol {
# CHECK:        Name: foo
# CHECK-NEXT:   Value: 0x0
# CHECK-NEXT:   Size: 0
# CHECK-NEXT:   Binding: Global
# CHECK-NEXT:   Type: None
# CHECK-NEXT:   Other: 0
# CHECK-NEXT:   Section: .text
# CHECK-NEXT: }

## Because of a bug we had a different behavior (different symbol 'foo' value)
## on a platforms that might use thunks, like AArch64. Check that issue is fixed.
# RUN: llvm-mc -filetype=obj -triple=aarch64-linux-gnu /dev/null -o %t.o
