They were wrongly relying on `Z3_INCLUDE_DIR` being passed through from LLVM, which is not the case for a standalone build. Instead, perform `find_package(Z3)` again to find Z3 development files and set `Z3_INCLUDE_DIR`. While at it, handle the possibility that Z3 development package is no longer installed -- run the tests only if both LLVM has been built against Z3, and the headers are still available. https://github.com/llvm/llvm-project/pull/145731#issuecomment-3009487525 Signed-off-by: Michał Górny <mgo...@gentoo.org> Added: Modified: clang/CMakeLists.txt clang/test/Analysis/z3-crosscheck-max-attempts.cpp clang/test/Analysis/z3/D83660.c clang/test/CMakeLists.txt clang/test/lit.cfg.py clang/test/lit.site.cfg.py.in Removed: ################################################################################ diff --git a/clang/CMakeLists.txt b/clang/CMakeLists.txt index 94607a8e8473c..1bb73599970c1 100644 --- a/clang/CMakeLists.txt +++ b/clang/CMakeLists.txt @@ -150,6 +150,12 @@ if(CLANG_BUILT_STANDALONE) endif() umbrella_lit_testsuite_begin(check-all) + + # If LLVM was built with Z3, check if we still have the headers around. + # They are used by a few tests. + if (LLVM_WITH_Z3) + find_package(Z3 4.8.9) + endif() endif() # LLVM_INCLUDE_TESTS endif() # standalone diff --git a/clang/test/Analysis/z3-crosscheck-max-attempts.cpp b/clang/test/Analysis/z3-crosscheck-max-attempts.cpp index 572e452fdcac2..312e442f23f4f 100644 --- a/clang/test/Analysis/z3-crosscheck-max-attempts.cpp +++ b/clang/test/Analysis/z3-crosscheck-max-attempts.cpp @@ -32,7 +32,7 @@ // RUN: Z3_SOLVER_RESULTS="UNDEF,UNDEF,SAT" %{mocked_clang} %{attempts}=3 -verify=accepted -// REQUIRES: z3, asserts, shell, system-linux +// REQUIRES: z3, z3-devel, asserts, shell, system-linux // refuted-no-diagnostics diff --git a/clang/test/Analysis/z3/D83660.c b/clang/test/Analysis/z3/D83660.c index 0a7c8bab8e345..2ca4a4d0b53e9 100644 --- a/clang/test/Analysis/z3/D83660.c +++ b/clang/test/Analysis/z3/D83660.c @@ -8,7 +8,7 @@ // RUN: %clang_cc1 -analyze -analyzer-constraints=z3 -setup-static-analyzer \ // RUN: -analyzer-checker=core %s -verify // -// REQUIRES: z3, asserts, shell, system-linux +// REQUIRES: z3, z3-devel, asserts, shell, system-linux // // Works only with the z3 constraint manager. // expected-no-diagnostics diff --git a/clang/test/CMakeLists.txt b/clang/test/CMakeLists.txt index e5b4a3bb84645..8baea5b0ca937 100644 --- a/clang/test/CMakeLists.txt +++ b/clang/test/CMakeLists.txt @@ -29,6 +29,14 @@ llvm_canonicalize_cmake_booleans( LLVM_EXPERIMENTAL_KEY_INSTRUCTIONS ) +# Run tests requiring Z3 headers only if LLVM was built with Z3 +# and the headers are available while building Clang -- the latter may +# not be the case when building standalone against installed LLVM. +set(TEST_WITH_Z3_DEVEL 0) +if(LLVM_WITH_Z3 AND Z3_FOUND) + set(TEST_WITH_Z3_DEVEL 1) +endif() + configure_lit_site_cfg( ${CMAKE_CURRENT_SOURCE_DIR}/lit.site.cfg.py.in ${CMAKE_CURRENT_BINARY_DIR}/lit.site.cfg.py diff --git a/clang/test/lit.cfg.py b/clang/test/lit.cfg.py index bbd95ef4b77de..6375e73f5df82 100644 --- a/clang/test/lit.cfg.py +++ b/clang/test/lit.cfg.py @@ -201,9 +201,11 @@ def have_host_clang_repl_cuda(): if config.clang_staticanalyzer_z3: config.available_features.add("z3") - config.substitutions.append( - ("%z3_include_dir", config.clang_staticanalyzer_z3_include_dir) - ) + if config.clang_staticanalyzer_z3_devel: + config.available_features.add("z3-devel") + config.substitutions.append( + ("%z3_include_dir", config.clang_staticanalyzer_z3_include_dir) + ) else: config.available_features.add("no-z3") diff --git a/clang/test/lit.site.cfg.py.in b/clang/test/lit.site.cfg.py.in index 00480d34852da..ec0e4aa10ed79 100644 --- a/clang/test/lit.site.cfg.py.in +++ b/clang/test/lit.site.cfg.py.in @@ -27,6 +27,7 @@ config.clang_default_pie_on_linux = @CLANG_DEFAULT_PIE_ON_LINUX@ config.clang_default_cxx_stdlib = "@CLANG_DEFAULT_CXX_STDLIB@" config.clang_staticanalyzer = @CLANG_ENABLE_STATIC_ANALYZER@ config.clang_staticanalyzer_z3 = @LLVM_WITH_Z3@ +config.clang_staticanalyzer_z3_devel = @TEST_WITH_Z3_DEVEL@ config.clang_staticanalyzer_z3_include_dir = "@Z3_INCLUDE_DIR@" config.clang_enable_cir = @CLANG_ENABLE_CIR@ config.clang_examples = @CLANG_BUILD_EXAMPLES@ _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
