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/gcc.dg/builtin-object-size-7.c | 71 ++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtin-object-size-7.c (limited to 'gcc/testsuite/gcc.dg/builtin-object-size-7.c') diff --git a/gcc/testsuite/gcc.dg/builtin-object-size-7.c b/gcc/testsuite/gcc.dg/builtin-object-size-7.c new file mode 100644 index 000000000..41742b974 --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtin-object-size-7.c @@ -0,0 +1,71 @@ +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +typedef __SIZE_TYPE__ size_t; +extern void *malloc (size_t); +extern void abort (void); + +struct A +{ + int i, j, k; + char buf[255]; + int l, m, n, o; +}; + +int +main (void) +{ + const size_t s = sizeof (struct A); + const size_t o = __builtin_offsetof (struct A, buf); + struct A *a = malloc (s); + struct A *b = malloc (o + 212); + if (__builtin_object_size (a->buf, 0) != s - o) + abort (); + if (__builtin_object_size (a->buf, 1) != sizeof (a->buf)) + abort (); + if (__builtin_object_size (a->buf, 2) != s - o) + abort (); + if (__builtin_object_size (a->buf, 3) != sizeof (a->buf)) + abort (); + if (__builtin_object_size (&a->buf[0], 0) != s - o) + abort (); + if (__builtin_object_size (&a->buf[0], 1) != sizeof (a->buf)) + abort (); + if (__builtin_object_size (&a->buf[0], 2) != s - o) + abort (); + if (__builtin_object_size (&a->buf[0], 3) != sizeof (a->buf)) + abort (); + if (__builtin_object_size (&a->buf[6], 0) != s - o - 6) + abort (); + if (__builtin_object_size (&a->buf[6], 1) != sizeof (a->buf) - 6) + abort (); + if (__builtin_object_size (&a->buf[6], 2) != s - o - 6) + abort (); + if (__builtin_object_size (&a->buf[6], 3) != sizeof (a->buf) - 6) + abort (); + if (__builtin_object_size (b->buf, 0) != 212) + abort (); + if (__builtin_object_size (b->buf, 1) != 212) + abort (); + if (__builtin_object_size (b->buf, 2) != 212) + abort (); + if (__builtin_object_size (b->buf, 3) != 212) + abort (); + if (__builtin_object_size (&b->buf[0], 0) != 212) + abort (); + if (__builtin_object_size (&b->buf[0], 1) != 212) + abort (); + if (__builtin_object_size (&b->buf[0], 2) != 212) + abort (); + if (__builtin_object_size (&b->buf[0], 3) != 212) + abort (); + if (__builtin_object_size (&b->buf[28], 0) != 212 - 28) + abort (); + if (__builtin_object_size (&b->buf[28], 1) != 212 - 28) + abort (); + if (__builtin_object_size (&b->buf[28], 2) != 212 - 28) + abort (); + if (__builtin_object_size (&b->buf[28], 3) != 212 - 28) + abort (); + return 0; +} -- cgit v1.2.3
