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/pr48335-5.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr48335-5.c (limited to 'gcc/testsuite/gcc.dg/pr48335-5.c') diff --git a/gcc/testsuite/gcc.dg/pr48335-5.c b/gcc/testsuite/gcc.dg/pr48335-5.c new file mode 100644 index 000000000..b1895484d --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr48335-5.c @@ -0,0 +1,38 @@ +/* PR middle-end/48335 */ +/* { dg-do compile } */ +/* { dg-options "-O2 -fno-tree-sra" } */ + +typedef long long T __attribute__((may_alias)); + +struct S +{ + _Complex float d __attribute__((aligned (8))); +}; + +int +f1 (struct S x) +{ + struct S s = x; + return *(T *) &s.d; +} + +int +f2 (struct S x) +{ + struct S s = x; + return *(char *) &s.d; +} + +int +f3 (struct S x) +{ + struct S s = x; + return ((char *) &s.d)[2]; +} + +int +f4 (struct S x, int y) +{ + struct S s = x; + return ((char *) &s.d)[y]; +} -- cgit v1.2.3
