/// This test validates that modules that depend on prebuilt modules /// resolve `is-in-stable-directories` correctly. /// The steps are: /// 1. Scan dependencies to build the PCH. One of the module's depend on header /// that is seemingly from the sysroot. However, it depends on a local header that is overlaid. /// 2. Build the PCH & dependency PCMs. /// 3. Scan a source file that transitively depends on the same modules as the pcm. // REQUIRES: shell // RUN: rm -rf %t // RUN: split-file %s %t // RUN: sed -e "s|DIR|%/t|g" %t/overlay.json.template > %t/overlay.json // RUN: sed -e "s|DIR|%/t|g" %t/compile-pch.json.in > %t/compile-pch.json // RUN: clang-scan-deps -compilation-database %t/compile-pch.json \ // RUN: -j 1 -format experimental-full > %t/deps_pch.db // RUN: %clang -x c-header -c %t/prebuild.h -isysroot %t/MacOSX.sdk \ // RUN: -I%t/BuildDir -ivfsoverlay %t/overlay.json \ // RUN: -I %t/MacOSX.sdk/usr/include -fmodules -fmodules-cache-path=%t/module-cache \ // RUN: -fimplicit-module-maps -o %t/prebuild.pch // RUN: sed -e "s|DIR|%/t|g" %t/compile-commands.json.in > %t/compile-commands.json // RUN: clang-scan-deps -compilation-database %t/compile-commands.json \ // RUN: -j 1 -format experimental-full > %t/deps.db // RUN: cat %t/deps_pch.db | sed 's:\\\\\?:/:g' | FileCheck %s -DPREFIX=%/t --check-prefix PCH_DEP // RUN: cat %t/deps.db | sed 's:\\\\\?:/:g' | FileCheck %s -DPREFIX=%/t --check-prefix CLIENT // PCH_DEP: "is-in-stable-directories": true // PCH_DEP: "name": "A" // PCH_DEP-NOT: "is-in-stable-directories": true // Verify is-in-stable-directories is only assigned to the module that only depends on A. // CLIENT-NOT: "is-in-stable-directories": true // CLIENT: "name": "D" // CLIENT: "is-in-stable-directories": true // CLIENT: "name": "sys" // CLIENT-NOT: "is-in-stable-directories": true //--- compile-pch.json.in [ { "directory": "DIR", "command": "clang -x c-header -c DIR/prebuild.h -isysroot DIR/MacOSX.sdk -IDIR/BuildDir -ivfsoverlay DIR/overlay.json -IDIR/MacOSX.sdk/usr/include -fmodules -fmodules-cache-path=DIR/module-cache -fimplicit-module-maps -o DIR/prebuild.pch", "file": "DIR/prebuild.h" } ] //--- compile-commands.json.in [ { "directory": "DIR", "command": "clang -c DIR/client.c -isysroot DIR/MacOSX.sdk -IDIR/BuildDir -ivfsoverlay DIR/overlay.json -IDIR/MacOSX.sdk/usr/include -fmodules -fmodules-cache-path=DIR/module-cache -fimplicit-module-maps -include-pch DIR/prebuild.pch", "file": "DIR/client.c" } ] //--- overlay.json.template { "version": 0, "case-sensitive": "false", "roots": [ { "external-contents": "DIR/BuildDir/B_vfs.h", "name": "DIR/MacOSX.sdk/usr/include/B/B_vfs.h", "type": "file" } ] } //--- MacOSX.sdk/usr/include/A/module.modulemap module A [system] { umbrella "." } //--- MacOSX.sdk/usr/include/A/A.h typedef int A_type; //--- MacOSX.sdk/usr/include/B/module.modulemap module B [system] { umbrella "." } //--- MacOSX.sdk/usr/include/B/B.h #include //--- BuildDir/B_vfs.h typedef int local_t; //--- MacOSX.sdk/usr/include/sys/sys.h #include typedef int sys_t_m; //--- MacOSX.sdk/usr/include/sys/module.modulemap module sys [system] { umbrella "." } //--- MacOSX.sdk/usr/include/B_transitive/B.h #include //--- MacOSX.sdk/usr/include/B_transitive/module.modulemap module B_transitive [system] { umbrella "." } //--- MacOSX.sdk/usr/include/C/module.modulemap module C [system] { umbrella "." } //--- MacOSX.sdk/usr/include/C/C.h #include //--- MacOSX.sdk/usr/include/D/module.modulemap module D [system] { umbrella "." } //--- MacOSX.sdk/usr/include/D/D.h #include //--- prebuild.h #include #include // This dependency transitively depends on a local header. //--- client.c #include #include // This dependency transitively depends on a local header.
