No compiler other than Clang seems to allow this,and it doesn't seem like a useful thing to accept as an extension in general.The current behavior was added for PR5957, where the problem was specificallyrelated to mismatches of the exception specification on the implicitly-declaredglobal operator new and delete. To retain that workaround, we downgrade theerror to an ExtWarn when the declaration is of a replaceable global allocationfunction.Now that this is an error, stop trying (and failing) to recover from a missingcomputed noexcept specification. That recovery didn't work, and led to crashesin code like the added testcase.llvm-svn: 248867 List of files: /llvm-project-15.0.7/clang/test/CXX/except/except.spec/p4.cpp Wed, 30 Sep 2015 00:48:50 +0000 Richard Smith <richard-llvm@metafoo.co.uk> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CXX/except/except.spec/p4.cpp#e934af8e Preserve exception specs in function decl merging.Exception specs are not part of the canonical type, but we shouldn'tdrop them just because we merged a noreturn attribute.Fixes PR17110.llvm-svn: 190206 List of files: /llvm-project-15.0.7/clang/test/CXX/except/except.spec/p4.cpp Fri, 06 Sep 2013 21:09:09 +0000 Eli Friedman <eli.friedman@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CXX/except/except.spec/p4.cpp#66f3ac9d Rework implementation of DR1492: Apply the resolution to operator delete too,since it also has an implicit exception specification. Downgrade the error toan extwarn, since at least for operator delete, system headers like to declareit as 'noexcept' whereas the implicit definition does not have an explicitexception specification. Move the exception specification for user-declared'operator delete' functions from the type-as-written into the type, to reflectreality and to allow us to detect whether there was an implicit exception specor not.llvm-svn: 166372 List of files: /llvm-project-15.0.7/clang/test/CXX/except/except.spec/p4.cpp Sat, 20 Oct 2012 08:26:51 +0000 Richard Smith <richard-llvm@metafoo.co.uk>
