From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/c-c++-common/builtin-offsetof.c | 29 +++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/c-c++-common/builtin-offsetof.c (limited to 'gcc/testsuite/c-c++-common/builtin-offsetof.c') diff --git a/gcc/testsuite/c-c++-common/builtin-offsetof.c b/gcc/testsuite/c-c++-common/builtin-offsetof.c new file mode 100644 index 000000000..6d9777546 --- /dev/null +++ b/gcc/testsuite/c-c++-common/builtin-offsetof.c @@ -0,0 +1,29 @@ +// Contributed by Dodji Seketeli +// Origin PR c++/38699 +// { dg-options "-Warray-bounds" } +// { dg-do compile } + +struct A +{ + const char *p; +}; + +struct B +{ + char p[10]; + struct A a; +}; + +void +f0 () +{ + __builtin_offsetof(struct A, p); // OK + __builtin_offsetof(struct A, p[0]); // { dg-error "non constant address" } + __builtin_offsetof(struct B, p[0]); // OK + __builtin_offsetof(struct B, p[9]); // OK + __builtin_offsetof(struct B, p[10]); // OK + __builtin_offsetof(struct B, p[11]); // { dg-warning "greater than size" } + __builtin_offsetof(struct B, a.p); // OK + __builtin_offsetof(struct B, p[0]); // OK + __builtin_offsetof(struct B, a.p[0]); // { dg-error "non constant address" } +} -- cgit v1.2.3
