The resulting function would be globally declared asextern int func(); -- a function without a prototype which accepts zeroor more arguments.C99 removed support for this questionable feature due to severesecurity concerns. However, there was no deprecation period; C89 hadthe feature, C99 didn't. So Clang (and GCC) both supported thefunctionality as an extension in C99 and later modes.C2x no longer supports that function signature as it now requires allfunctions to have a prototype, and given the known security issues withthe feature, continuing to support it as an extension is not tenable.This patch changes the diagnostic behavior for the-Wimplicit-function-declaration warning group depending on the languagemode in effect. We continue to warn by default in C89 mode (due to thefeature being dangerous to use). However, because this feature will notbe supported in C2x mode, we've diagnosed it as being invalid for solong, the security concerns with the feature, and the trivialworkaround for users (declare the function), we now default theextension warning to an error in C99-C17 mode. This still gives usersan easy workaround if they are extensively using the extension in thosemodes (they can disable the warning or use -Wno-error to downgrade theerror), but the new diagnostic makes it more clear that this feature isnot supported and should be avoided. In C2x mode, we no longer allow animplicit function to be defined and treat the situation the same as anyother lookup failure.Differential Revision: https://reviews.llvm.org/D122983 List of files: /llvm-project-15.0.7/clang/test/CodeGen/decl.c Wed, 20 Apr 2022 15:25:35 +0000 Aaron Ballman <aaron@aaronballman.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGen/decl.c#532dc62b [OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)This adds -no-opaque-pointers to clang tests whose output willchange when opaque pointers are enabled by default. 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/CodeGen/decl.c 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/CodeGen/decl.c#adc402bf Use functions with prototypes when appropriate; NFCA significant number of our tests in C accidentally use functionswithout prototypes. This patch converts the function signatures to havea prototype for the situations where the test is not specific to K&R Cdeclarations. e.g., void func();becomes void func(void);This is the eleventh batch of tests being updated (there are asignificant number of other tests left to be updated).
