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/PCH/block-helpers.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/PCH/block-helpers.cpp#8e57b07f Distinguish `__block` variables that are captured by escaping blocksfrom those that aren't.This patch changes the way __block variables that aren't captured byescaping blocks are handled:- Since non-escaping blocks on the stack never get copied to the heap (see https://reviews.llvm.org/D49303), Sema shouldn't error out when the type of a non-escaping __block variable doesn't have an accessible copy constructor.- IRGen doesn't have to use the specialized byref structure (see https://clang.llvm.org/docs/Block-ABI-Apple.html#id8) for a non-escaping __block variable anymore.

Often these functions are equivalent for different blocks.This commit makes changes to merge equivalent copy and dispose helperfunctions and reduce code size.To enable merging equivalent copy/dispose functions, the captured objectinfomation is encoded into the helper function name. This allows IRGento check whether an equivalent helper function has already been emittedand reuse the function instead of generating a new helper functionwhenever a block is defined. In addition, the helper functions aremarked as linkonce_odr to enable merging helper functions that have thesame name across translation units and marked as unnamed_addr to enablethe linker's deduplication pass to merge functions that have differentnames but the same content.rdar://problem/42640608Differential Revision: https://reviews.llvm.org/D50152llvm-svn: 339438 List of files: /llvm-project-15.0.7/clang/test/PCH/block-helpers.cpp Fri, 10 Aug 2018 15:09:24 +0000 Akira Hatanaka <ahatanaka@apple.com>
