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.c-torture/execute/20011113-1.c | 55 ++++++++++++++++++++++++ 1 file changed, 55 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20011113-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20011113-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20011113-1.c b/gcc/testsuite/gcc.c-torture/execute/20011113-1.c new file mode 100644 index 000000000..a2eb86b6d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20011113-1.c @@ -0,0 +1,55 @@ +typedef __SIZE_TYPE__ size_t; +extern void *memcpy (void *__restrict, const void *__restrict, size_t); +extern void abort (void); +extern void exit (int); + +typedef struct t +{ + unsigned a : 16; + unsigned b : 8; + unsigned c : 8; + long d[4]; +} *T; + +typedef struct { + long r[3]; +} U; + +T bar (U, unsigned int); + +T foo (T x) +{ + U d, u; + + memcpy (&u, &x->d[1], sizeof u); + d = u; + return bar (d, x->b); +} + +T baz (T x) +{ + U d, u; + + d.r[0] = 0x123456789; + d.r[1] = 0xfedcba987; + d.r[2] = 0xabcdef123; + memcpy (&u, &x->d[1], sizeof u); + d = u; + return bar (d, x->b); +} + +T bar (U d, unsigned int m) +{ + if (d.r[0] != 21 || d.r[1] != 22 || d.r[2] != 23) + abort (); + return 0; +} + +struct t t = { 26, 0, 0, { 0, 21, 22, 23 }}; + +int main (void) +{ + baz (&t); + foo (&t); + exit (0); +} -- cgit v1.2.3
