From 66c5fd6c537269eaef0f630fa14360dcaff6a295 Mon Sep 17 00:00:00 2001 From: Jeff Cohen Date: Sun, 23 Oct 2005 04:37:20 +0000 Subject: When a function takes a variable number of pointer arguments, with a zero pointer marking the end of the list, the zero *must* be cast to the pointer type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will not extend the zero to 64 bits, thus allowing the upper 32 bits to be random junk. The new END_WITH_NULL macro may be used to annotate a such a function so that GCC (version 4 or newer) will detect the use of un-casted zero at compile time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23888 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Debugger/UnixLocalInferiorProcess.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'lib/Debugger') diff --git a/lib/Debugger/UnixLocalInferiorProcess.cpp b/lib/Debugger/UnixLocalInferiorProcess.cpp index 1731bea..6758e2d 100644 --- a/lib/Debugger/UnixLocalInferiorProcess.cpp +++ b/lib/Debugger/UnixLocalInferiorProcess.cpp @@ -924,7 +924,8 @@ static void runChild(Module *M, const std::vector &Arguments, // If the program didn't explicitly call exit, call exit now, for the program. // This ensures that any atexit handlers get called correctly. - Function *Exit = M->getOrInsertFunction("exit", Type::VoidTy, Type::IntTy, 0); + Function *Exit = M->getOrInsertFunction("exit", Type::VoidTy, Type::IntTy, + (Type *)0); std::vector Args; GenericValue ResultGV; -- cgit v1.1
