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/struct-cpy-1.c | 43 ++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/struct-cpy-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/struct-cpy-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/struct-cpy-1.c b/gcc/testsuite/gcc.c-torture/execute/struct-cpy-1.c new file mode 100644 index 000000000..52886feee --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/struct-cpy-1.c @@ -0,0 +1,43 @@ +/* powerpc64-linux gcc miscompiled this due to rs6000.c:expand_block_move + not setting mem aliasing info correctly for the code implementing the + structure assignment. */ + +struct termios +{ + unsigned int a; + unsigned int b; + unsigned int c; + unsigned int d; + unsigned char pad[28]; +}; + +struct tty_driver +{ + unsigned char pad1[38]; + struct termios t __attribute__ ((aligned (8))); +}; + +static struct termios zero_t; +static struct tty_driver pty; + +void ini (void) +{ + pty.t = zero_t; + pty.t.a = 1; + pty.t.b = 2; + pty.t.c = 3; + pty.t.d = 4; +} + +int main (void) +{ + extern void abort (void); + + ini (); + if (pty.t.a != 1 + || pty.t.b != 2 + || pty.t.c != 3 + || pty.t.d != 4) + abort (); + return 0; +} -- cgit v1.2.3
