// The OpenMP standard defines 3 ways of providing ompt_start_tool:
// 1. "statically-linking the tool’s definition of ompt_start_tool into an
// OpenMP application"
// RUN: %libomp-compile -DCODE -DTOOL && \
// RUN: env OMP_TOOL_VERBOSE_INIT=stdout %libomp-run | \
// RUN: FileCheck %s --check-prefixes CHECK,ADDRSPACE
// Note: We should compile the tool without -fopenmp as other tools developer
// would do. Otherwise this test may pass for the wrong reasons on Darwin.
// RUN: %clang %flags -DTOOL -shared -fPIC %s -o %T/tool.so
// 2. "introducing a dynamically-linked library that includes the tool’s
// definition of ompt_start_tool into the application’s address space"
// 2.1 Link with tool during compilation
// RUN: %libomp-compile -DCODE %no-as-needed-flag %T/tool.so && \
// RUN: env OMP_TOOL_VERBOSE_INIT=stdout %libomp-run | \
// RUN: FileCheck %s --check-prefixes CHECK,ADDRSPACE
// 2.2 Link with tool during compilation, but AFTER the runtime
// RUN: %libomp-compile -DCODE -lomp %no-as-needed-flag %T/tool.so && \
// RUN: env OMP_TOOL_VERBOSE_INIT=stdout %libomp-run | \
// RUN: FileCheck %s --check-prefixes CHECK,ADDRSPACE
// 2.3 Inject tool via the dynamic loader
// RUN: %libomp-compile -DCODE && \
// RUN: env OMP_TOOL_VERBOSE_INIT=stdout %preload-tool %libomp-run | \
// RUN: FileCheck %s --check-prefixes CHECK,ADDRSPACE
// 3. "providing the name of a dynamically-linked library appropriate for the
// architecture and operating system used by the application in the
// tool-libraries-var ICV"
// RUN: %libomp-compile -DCODE && env OMP_TOOL_LIBRARIES=%T/tool.so \
// RUN: OMP_TOOL_VERBOSE_INIT=stdout %libomp-run | \
// RUN: FileCheck %s -DPARENTPATH=%T --check-prefixes CHECK,TOOLLIB
// REQUIRES: ompt
