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.dg/Wstrict-aliasing-bogus-ref-all-2.c | 26 ++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c (limited to 'gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c') diff --git a/gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c b/gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c new file mode 100644 index 000000000..29b1e98ba --- /dev/null +++ b/gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all-2.c @@ -0,0 +1,26 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -Wall" } */ + +typedef long long __m128i __attribute__ ((__vector_size__ (16), __may_alias__)); + +extern __inline __m128i __attribute__((__gnu_inline__, __always_inline__, __artificial__)) +_mm_load_si128 (__m128i const *__P) +{ + return *__P; +} + +static const short __attribute__((__aligned__(16))) tbl[8] = +{ 1, 2, 3, 4, 5, 6, 7, 8}; + + +__m128i get_vec(void) +{ + __m128i ret; + + ret = _mm_load_si128((__m128i *)tbl); /* { dg-bogus "type-punning" } */ + + return ret; +} + +/* Ignore a warning that is irrelevant to the purpose of this test. */ +/* { dg-prune-output ".*GCC vector returned by reference.*" } */ -- cgit v1.2.3
