From 2e72da947c48005ed14ca78f61f7a43abf4c58e9 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Tue, 1 Mar 2011 00:03:48 +0000 Subject: -fwrapv should turn off the inbounds markers from geps used for pointer arithmetic. This is part of PR9256, it would be great if someone else wired up -fno-strict-overflow in the driver to -fwrapv. llvm-svn: 126718 --- clang/test/CodeGen/integer-overflow.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'clang/test/CodeGen/integer-overflow.c') diff --git a/clang/test/CodeGen/integer-overflow.c b/clang/test/CodeGen/integer-overflow.c index 103cc842..066ef89 100644 --- a/clang/test/CodeGen/integer-overflow.c +++ b/clang/test/CodeGen/integer-overflow.c @@ -49,4 +49,12 @@ void test1() { // TRAPV: llvm.sadd.with.overflow.i32({{.*}}, i32 -1) // TRAPV_HANDLER: foo( --a; + + + // -fwrapv should turn off inbounds for GEP's, PR9256 + extern int* P; + ++P; + // DEFAULT: getelementptr inbounds i32* + // WRAPV: getelementptr i32* + // TRAPV: getelementptr inbounds i32* } -- cgit v1.1
