Sema: Accept pointers to any address space for builtin functions As long as they don't have an address space explicitly defined. This allows builtins with pointer arguments to be used with OpenCL. llvm-svn: 233706 2015-03-31 16:39:02 +00:00			`// RUN: %clang_cc1 %s -fsyntax-only -verify -pedantic`

[Sema] Handle errors during rewriteBuiltinFunctionDecl rewriteBuiltinFunctionDecl can encounter errors when performing DefaultFunctionArrayLvalueConversion. These errors were not handled which led to a null pointer dereference. This fixes PR28651. llvm-svn: 276352 2016-07-21 23:03:43 +00:00
Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); 2022-03-31 13:43:53 -04:00			`void pr28651(void) {`
