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.c-torture/execute/builtins/pr22237.c | 44 ++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/pr22237.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/pr22237.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/pr22237.c b/gcc/testsuite/gcc.c-torture/execute/builtins/pr22237.c new file mode 100644 index 000000000..957a47c0f --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/pr22237.c @@ -0,0 +1,44 @@ +extern void abort (void); +extern void exit (int); +struct s { unsigned char a[256]; }; +union u { struct { struct s b; int c; } d; struct { int c; struct s b; } e; }; +static union u v; +static union u v0; +static struct s *p = &v.d.b; +static struct s *q = &v.e.b; + +static inline struct s rp (void) { return *p; } +static inline struct s rq (void) { return *q; } +static void pq (void) { *p = rq(); } +static void qp (void) { *q = rp(); } + +static void +init (struct s *sp) +{ + int i; + for (i = 0; i < 256; i++) + sp->a[i] = i; +} + +static void +check (struct s *sp) +{ + int i; + for (i = 0; i < 256; i++) + if (sp->a[i] != i) + abort (); +} + +void +main_test (void) +{ + v = v0; + init (p); + qp (); + check (q); + v = v0; + init (q); + pq (); + check (p); + exit (0); +} -- cgit v1.2.3
