c3fe8ddd - Allow -Wno-gnu to silence GNU extensions related to pointer arithmetic

Tue, 22 Mar 2022 17:14:16 +0000

Allow -Wno-gnu to silence GNU extensions related to pointer arithmeticThese diagnostics were added to a diagnostic group, but that diagnosticgroup was not under -Wgnu. I've now split them into their owndiagnostic group that is added both to the original group (so user'scurrently opting in or out of these should not see a change) and underthe -Wgnu group so that -Wno-gnu can be used to disable all GNUextension diagnostics. This fixes Issue 54444. List of files: /llvm-project-15.0.7/clang/test/Sema/pointer-addition.c

c9332218 - Factor out (some of) the checking for invalid forms of pointer

Mon, 27 Jun 2011 08:02:19 +0000

Factor out (some of) the checking for invalid forms of pointerarithmetic into a couple of common routines. Use these to make themessages more consistent in the various contexts, especially in terms ofconsistently diagnosing binary operators with invalid types on both theleft- and right-hand side. Also, improve the grammar and wording of themessages some, handling both two pointers and two (different) types.The wording of function pointer arithmetic diagnostics still strikes meas poorly phrased, and I worry this makes them slightly more awkward ifmore consistent. I'm hoping to fix that with a follow-on patch and testcase that will also make them more helpful when a typedef or templatetype parameter makes the type completely opaque.Suggestions on better wording are very welcome, thanks to Richard Smithfor some initial help on that front.llvm-svn: 133906 List of files: /llvm-project-15.0.7/clang/test/Sema/pointer-addition.c

8fbe78f6 - Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.

Tue, 15 Dec 2009 20:14:24 +0000

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/Sema/pointer-addition.c
