This test 4 // checks such arguments are removed from the command-lines: '-include', 5 // '-dwarf-debug-flag' and '-main-file-name'. Similarly, several arguments 6 // such as '-fmodules-cache-path=' are only relevant for implicit modules, and 7 // are removed to better-canonicalize the compilation. 8 9 // RUN: rm -rf %t && mkdir %t 10 // RUN: cp %S/Inputs/removed-args/* %t 11 // RUN: touch %t/build-session 12 13 // RUN: sed "s|DIR|%/t|g" %S/Inputs/removed-args/cdb.json.template > %t/cdb.json 14 // RUN: clang-scan-deps -compilation-database %t/cdb.json -format experimental-full > %t/result.json 15 // RUN: cat %t/result.json | sed 's:\\\\\?:/:g' | FileCheck %s -DPREFIX=%/t 16 // 17 // CHECK: { 18 // CHECK-NEXT: "modules": [ 19 // CHECK-NEXT: { 20 // CHECK-NEXT: "clang-module-deps": [], 21 // CHECK-NEXT: "clang-modulemap-file": "[[PREFIX]]/module.modulemap", 22 // CHECK-NEXT: "command-line": [ 23 // CHECK-NEXT: "-cc1" 24 // CHECK-NOT: "-dwarf-debug-flags" 25 // CHECK-NOT: "-main-file-name" 26 // CHECK-NOT: "-include" 27 // CHECK-NOT: "-fmodules-cache-path= 28 // CHECK-NOT: "-fmodules-validate-once-per-build-session" 29 // CHECK-NOT: "-fbuild-session-timestamp= 30 // CHECK-NOT: "-fmodules-prune-interval= 31 // CHECK-NOT: "-fmodules-prune-after= 32 // CHECK-NOT: "-dependency-file" 33 // CHECK-NOT: "-MT" 34 // CHECK-NOT: "-serialize-diagnostic-file" 35 // CHECK: ], 36 // CHECK-NEXT: "context-hash": "[[HASH_MOD_HEADER:.*]]", 37 // CHECK-NEXT: "file-deps": [ 38 // CHECK-NEXT: "[[PREFIX]]/mod_header.h", 39 // CHECK-NEXT: "[[PREFIX]]/module.modulemap" 40 // CHECK-NEXT: ], 41 // CHECK-NEXT: "name": "ModHeader" 42 // CHECK-NEXT: }, 43 // CHECK-NEXT: { 44 // CHECK-NEXT: "clang-module-deps": [], 45 // CHECK-NEXT: "clang-modulemap-file": "[[PREFIX]]/module.modulemap", 46 // CHECK-NEXT: "command-line": [ 47 // CHECK-NEXT: "-cc1" 48 // CHECK-NOT: "-dwarf-debug-flags" 49 // CHECK-NOT: "-main-file-name" 50 // CHECK-NOT: "-include" 51 // CHECK-NOT: "-fmodules-cache-path= 52 // CHECK-NOT: "-fmodules-validate-once-per-build-session" 53 // CHECK-NOT: "-fbuild-session-timestamp= 54 // CHECK-NOT: "-fmodules-prune-interval= 55 // CHECK-NOT: "-fmodules-prune-after= 56 // CHECK-NOT: "-dependency-file" 57 // CHECK-NOT: "-MT" 58 // CHECK-NOT: "-serialize-diagnostic-file" 59 // CHECK: ], 60 // CHECK-NEXT: "context-hash": "[[HASH_MOD_TU:.*]]", 61 // CHECK-NEXT: "file-deps": [ 62 // CHECK-NEXT: "[[PREFIX]]/mod_tu.h", 63 // CHECK-NEXT: "[[PREFIX]]/module.modulemap" 64 // CHECK-NEXT: ], 65 // CHECK-NEXT: "name": "ModTU" 66 // CHECK-NEXT: } 67 // CHECK-NEXT: ], 68 // CHECK-NEXT: "translation-units": [ 69 // CHECK-NEXT: { 70 // CHECK-NEXT: "clang-context-hash": "[[HASH_TU:.*]]", 71 // CHECK-NEXT: "clang-module-deps": [ 72 // CHECK-NEXT: { 73 // CHECK-NEXT: "context-hash": "[[HASH_MOD_HEADER]]", 74 // CHECK-NEXT: "module-name": "ModHeader" 75 // CHECK-NEXT: }, 76 // CHECK-NEXT: { 77 // CHECK-NEXT: "context-hash": "[[HASH_MOD_TU]]", 78 // CHECK-NEXT: "module-name": "ModTU" 79 // CHECK-NEXT: } 80 // CHECK-NEXT: ] 81 // CHECK-NEXT: "command-line": [ 82 // CHECK-NEXT: "-fsyntax-only", 83 // CHECK-NOT: "-fmodules-cache-path= 84 // CHECK-NOT: "-fmodules-validate-once-per-build-session" 85 // CHECK-NOT: "-fbuild-session-file= 86 // CHECK-NOT: "-fmodules-prune-interval= 87 // CHECK-NOT: "-fmodules-prune-after= 88 // CHECK: ], 89 // CHECK: } 90 // CHECK-NEXT: ] 91 // CHECK-NEXT: } 92
