realincubus added a comment. @bkramer I can verify that after building this with clang 3.9 in release mode it does not work anymore like expected. everything is fine in debug mode
if i look at the output generated from llvm::sys::DynamicLibrary::LoadLibraryPermanently in 1761 CompilerInstance::loadPlugins() i get errors like /home/incubus/llvm_patch_test/build/lib/ClangPlugin.so /home/incubus/llvm_patch_test/build/lib/ClangPlugin.so: undefined symbol: _ZN5clang17ASTFrontendAction13ExecuteActionEv In my original patch http://reviews.llvm.org/D5611 I added a list of symbols that had to be exported in order to make libclang work with plugins like expected. After adding the symbols from the original patch and 2 additional ones it is ok now with clang version 3.9 in release mode. Symbols needed: _ZN5clang15PluginASTAction6anchorEv _ZN4llvm11raw_ostream5writeEPKcm _ZN4llvm4errsEv _ZN5clang11ASTConsumer33HandleTopLevelDeclInObjCContainerENS_12DeclGroupRefE _ZN5clang14FrontendActionD2Ev _ZN5clang13DiagnosticIDs15getCustomDiagIDENS0_5LevelEN4llvm9StringRefE _ZN5clang17ASTFrontendAction13ExecuteActionEv _ZN5clang11ASTConsumer24HandleImplicitImportDeclEPNS_10ImportDeclE _ZN5clang14FrontendAction22shouldEraseOutputFilesEv _ZNK5clang15DeclarationName11getAsStringEv _ZN5clang17DiagnosticsEngine21EmitCurrentDiagnosticEb _ZN5clang11ASTConsumer21HandleInterestingDeclENS_12DeclGroupRefE _ZN5clang14FrontendActionC2Ev _ZN4llvm8RegistryIN5clang15PluginASTActionENS_14RegistryTraitsIS2_EEE4nodeC1ERKNS_19SimpleRegistryEntryIS2_EE _ZTVN5clang15PluginASTActionE _ZTVN5clang17ASTFrontendActionE _ZTVN5clang11ASTConsumerE _ZN4llvm8RegistryIN5clang15PluginASTActionEE4HeadE _ZN4llvm8RegistryIN5clang15PluginASTActionEE4TailE Please tell me if I am wrong, but "tools/libclang/libclang.exports" is kind of a filter. Everything that is not listed in this file is not exported as a symbol in the resulting libclang.so file. Is there a way to automatically add the needed symbols to the exports file ? http://reviews.llvm.org/D15729 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
