From 933f67887fcce41e73655b33da237e6bc61a46ea Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 12 Apr 2010 21:10:05 +0000 Subject: fix PR6660/6168: emit padding as zeros instead of undef. Because trailing fields may not be represented in initializer lists, they are being handled as padding and those fields *must* be zero initialized. llvm-svn: 101067 --- clang/test/CodeGen/union-init2.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'clang/test/CodeGen/union-init2.c') diff --git a/clang/test/CodeGen/union-init2.c b/clang/test/CodeGen/union-init2.c index ac469cd4b51..bd56f9e688a 100644 --- a/clang/test/CodeGen/union-init2.c +++ b/clang/test/CodeGen/union-init2.c @@ -1,4 +1,7 @@ -// RUN: %clang_cc1 -emit-llvm %s -o - -triple i686-pc-linux-gnu | grep "bitcast (%0\* @r to %union.x\*), \[4 x i8\] undef" +// RUN: %clang_cc1 -emit-llvm %s -o - -triple i686-pc-linux-gnu | FileCheck %s // Make sure we generate something sane instead of a ptrtoint union x {long long b;union x* a;} r = {.a = &r}; + + +// CHECK: bitcast (%0* @r to %union.x*), [4 x i8] zero \ No newline at end of file -- cgit v1.2.3
