# Test that BOLT will instrument a statically linked PIE using entry point
# patching.

# REQUIRES: system-linux,bolt-runtime,target=x86_64-{{.*}}

# RUN: llvm-mc -triple x86_64 -filetype=obj %s -o %t.o
# Using lld directly and not specifying and interpreter effectlively generates a static pie.
# RUN: ld.lld -q -pie -o %t.exe %t.o
# RUN: llvm-bolt --instrument --instrumentation-sleep-time=1 \
# RUN:   -o %t.out %t.exe 2>&1 | FileCheck %s

# CHECK: static pie executable detected
# CHECK: runtime library initialization was hooked via ELF Header Entry Point
