From 2cb4222338669a3e70b546ef264fbd5d3f96aef5 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126718 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/integer-overflow.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'test/CodeGen/integer-overflow.c') diff --git a/test/CodeGen/integer-overflow.c b/test/CodeGen/integer-overflow.c index 103cc8427b..066ef89574 100644 --- a/test/CodeGen/integer-overflow.c +++ b/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 v1.2.3-18-g5258
