OpenMP 5.1 introduces the new env variable OMP_TOOL_VERBOSE_INIT=(disabled|stdout|stderr|<filename>) to enable verbose loading and initialization of OMPT tools. This env variable helps to understand the cause when loading of a tool fails (e.g., undefined symbols or dependency not in LD_LIBRARY_PATH) Output of OMP_TOOL_VERBOSE_INIT is added for OMP_DISPLAY_ENV Tests for this patch are integrated into the different existing tool loading tests, making these tests more verbose. An Archer specific verbose test is integrated into an existing Archer test. Patch prepared by: Isabel Thärigen Differential Revision: https://reviews.llvm.org/D91464

// 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 && env OMP_TOOL_VERBOSE_INIT=stdout \
|
||
// RUN: %libomp-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 | FileCheck %s \
|
||
// RUN: --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 | FileCheck %s \
|
||
// RUN: --check-prefixes CHECK,ADDRSPACE
|
||
|
||
// 2.3 Inject tool via the dynamic loader
|
||
|
||
// RUN: %libomp-compile -DCODE && env OMP_TOOL_VERBOSE_INIT=stdout \
|
||
// RUN: %preload-tool %libomp-run | FileCheck %s \
|
||
// RUN: --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"
|
||
|
||
// 3.1 OMP_TOOL_VERBOSE_INIT not set

||
// 3.4 OMP_TOOL_VERBOSE_INIT to stderr, check merged stdout and stderr
|
||
|
||
// RUN: env OMP_TOOL_LIBRARIES=%T/tool.so OMP_TOOL_VERBOSE_INIT=stderr \
|
||
// RUN: %libomp-run 2>&1 | \

// 3.6 OMP_TOOL_VERBOSE_INIT to file "init.log"
|
