<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang @llvm/pr-subscribers-clang-driver Author: dong jianqiang (dongjianqiang2) <details> <summary>Changes</summary> clang splits -export-dynamic into "-e" and "xport-dynamic", and gets ld warning: cannot find entry symbol xport-dynamic; defaulting to XXXX, which is unexpected from user. Adjust the driver to support -export-dynamic, which can match GCC behavior. --- Full diff: https://github.com/llvm/llvm-project/pull/72781.diff 2 Files Affected: - (modified) clang/include/clang/Driver/Options.td (+1) - (modified) clang/test/Driver/dynamic-linker.c (+6) ``````````diff diff --git a/clang/include/clang/Driver/Options.td b/clang/include/clang/Driver/Options.td index df12ba8fbcb296a..3bb764a1e46ab8a 100644 --- a/clang/include/clang/Driver/Options.td +++ b/clang/include/clang/Driver/Options.td @@ -1453,6 +1453,7 @@ def extract_api_ignores_EQ: CommaJoined<["--"], "extract-api-ignores=">, HelpText<"Comma separated list of files containing a new line separated list of API symbols to ignore when extracting API information.">, MarshallingInfoStringVector<FrontendOpts<"ExtractAPIIgnoresFileList">>; def e : JoinedOrSeparate<["-"], "e">, Flags<[LinkerInput]>, Group<Link_Group>; +def export_dynamic : Flag<["-"], "export-dynamic">, Flags<[LinkerInput]>, Group<Link_Group>; def fmax_tokens_EQ : Joined<["-"], "fmax-tokens=">, Group<f_Group>, Visibility<[ClangOption, CC1Option]>, HelpText<"Max total number of preprocessed tokens for -Wmax-tokens.">, diff --git a/clang/test/Driver/dynamic-linker.c b/clang/test/Driver/dynamic-linker.c index 978907e0adee697..d202f537b44fb98 100644 --- a/clang/test/Driver/dynamic-linker.c +++ b/clang/test/Driver/dynamic-linker.c @@ -23,6 +23,12 @@ // RUN: %clang -target powerpc64-unknown-linux-gnu -### -static /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-STATIC %s // RUN: %clang -target x86_64-unknown-linux-gnu -### -static /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-STATIC %s +// RUN: %clang -target armv7-unknown-linux-gnueabi -### -export-dynamic /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-RDYNAMIC %s +// RUN: %clang -target i386-unknown-linux-gnu -### -export-dynamic /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-RDYNAMIC %s +// RUN: %clang -target mips64-unknown-linux-gnu -### -export-dynamic /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-RDYNAMIC %s +// RUN: %clang -target powerpc64-unknown-linux-gnu -### -export-dynamic /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-RDYNAMIC %s +// RUN: %clang -target x86_64-unknown-linux-gnu -### -export-dynamic /dev/null -o /dev/null 2>&1 | FileCheck -check-prefix CHECK-RDYNAMIC %s + // CHECK-SHARED: "-shared" // CHECK-RDYNAMIC: "-export-dynamic" // CHECK-STATIC: "-{{B?}}static" `````````` </details> https://github.com/llvm/llvm-project/pull/72781 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
