From 6a8673038b0c7e20962d732515cd2cd4812f52ef Mon Sep 17 00:00:00 2001 From: David Tenty Date: Tue, 10 May 2022 11:39:58 -0400 Subject: [PATCH] Reland [clang][AIX] add option mdefault-visibility-export-mapping The option mdefault-visibility-export-mapping is created to allow mapping default visibility to an explicit shared library export (e.g. dllexport). Exactly how and if this is manifested is target dependent (since it depends on how they map dllexport in the IR). Three values are provided for the option: * none: the default and behavior without the option, no additional export linkage information is created. * explicit: add the export for entities with explict default visibility from the source, including RTTI * all: add the export for all entities with default visibility This option is useful for targets which do not export symbols as part of their usual default linkage behaviour (e.g. AIX), such targets traditionally specified such information in external files (e.g. export lists), but this mapping allows them to use the visibility information typically used for this purpose on other (e.g. ELF) platforms. This relands commit: 8c8a2679a20f621994fa904bcfc68775e7345edc with fixes for the compile time and assert problems that were reported by: * making shouldMapVisibilityToDLLExport inline and provide an early return in the case where no mapping is in effect (aka non-AIX platforms) * don't try to export RTTI types which we will give internal linkage to Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D126340 --- clang/docs/UsersManual.rst | 17 + clang/include/clang/Basic/LangOptions.def | 1 + clang/include/clang/Basic/LangOptions.h | 23 + clang/include/clang/Driver/Options.td | 7 + clang/lib/CodeGen/CodeGenModule.cpp | 10 +- clang/lib/CodeGen/CodeGenModule.h | 8 + clang/lib/CodeGen/ItaniumCXXABI.cpp | 16 +- clang/lib/CodeGen/MicrosoftCXXABI.cpp | 6 +- clang/lib/Driver/ToolChains/Clang.cpp | 8 + .../CodeGen/mdefault-visibility-export-mapping.c | 29 + .../mdefault-visibility-export-mapping-alias.cpp | 41 ++ .../mdefault-visibility-export-mapping-rtti.cpp | 596 +++++++++++++++++++++ .../mdefault-visibility-export-mapping.cpp | 119 ++++ 13 files changed, 870 insertions(+), 11 deletions(-) create mode 100644 clang/test/CodeGen/mdefault-visibility-export-mapping.c create mode 100644 clang/test/CodeGenCXX/mdefault-visibility-export-mapping-alias.cpp create mode 100644 clang/test/CodeGenCXX/mdefault-visibility-export-mapping-rtti.cpp create mode 100644 clang/test/CodeGenCXX/mdefault-visibility-export-mapping.cpp diff --git a/clang/docs/UsersManual.rst b/clang/docs/UsersManual.rst index b8c4683..e12dc72 100644 --- a/clang/docs/UsersManual.rst +++ b/clang/docs/UsersManual.rst @@ -3626,6 +3626,23 @@ Clang expects the GCC executable "gcc.exe" compiled for `Some tests might fail `_ on ``x86_64-w64-mingw32``. +AIX +^^^ + +The ``-mdefault-visibility-export-mapping=`` option can be used to control +mapping of default visibility to an explicit shared object export +(i.e. XCOFF exported visibility).
