Add a testcase that checks wheter the runtime can handle an ompt_start_tool method that returns NULL indicating that no tool shall be loaded. All tool_available testcases need a separate folder to avoid file conflicts for the generated tools. Differential Revision: https://reviews.llvm.org/D41904 llvm-svn: 324587

// 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 && %libomp-run | FileCheck %s
|
||
|
||
// 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 -Wl,--no-as-needed %T/tool.so && %libomp-run | FileCheck %s
|
||
// 2.2 Link with tool during compilation, but AFTER the runtime
|
||
// RUN: %libomp-compile -DCODE -lomp -Wl,--no-as-needed %T/tool.so && %libomp-run | FileCheck %s
|
||
// 2.3 Inject tool via the dynamic loader
|
||
// RUN: %libomp-compile -DCODE && %preload-tool %libomp-run | FileCheck %s
|
||
|
||
// 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 %libomp-run | FileCheck %s
|
||
|
||
// REQUIRES: ompt
