This isintended to be part of the migration approach described inhttps://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.The patch has been produced by replacing %clang_cc1 with%clang_cc1 -no-opaque-pointers for tests that fail with opaquepointers enabled. Worth noting that this doesn't cover all tests,there's a remaining ~40 tests not using %clang_cc1 that will needa followup change.Differential Revision: https://reviews.llvm.org/D123115 List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/attr-retain.cpp Thu, 07 Apr 2022 10:03:55 +0000 Nikita Popov <npopov@redhat.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGenCXX/attr-retain.cpp#2e2ee430 [test] Add -triple x86_64 to attr-retain.cpp List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/attr-retain.cpp Sat, 27 Feb 2021 03:35:53 +0000 Fangrui Song <i@maskray.me> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGenCXX/attr-retain.cpp#8afdacba Add GNU attribute 'retain'For ELF targets, GCC 11 will set SHF_GNU_RETAIN on the section of a`__attribute__((retain))` function/variable to prevent linker garbagecollection. (See AttrDocs.td for the linker support).This patch adds `retain` functions/variables to the `llvm.used` list, which hasthe desired linker GC semantics. Note: `retain` does not imply `used`,so an unused function/variable can be dropped by Sema.Before 'retain' was introduced, previous ELF solutions require inline asm orlinker tricks, e.g. `asm volatile(".reloc 0, R_X86_64_NONE, target");`(architecture dependent) or define a non-local symbol in the section and use`ld -u`. There was no elegant source-level solution.With D97448, `__attribute__((retain))` will set `SHF_GNU_RETAIN` on ELF targets.Differential Revision: https://reviews.llvm.org/D97447 List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/attr-retain.cpp Fri, 26 Feb 2021 19:59:53 +0000 Fangrui Song <i@maskray.me>
