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/array-init-2.c | 51 +++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/array-init-2.c (limited to 'gcc/testsuite/gcc.dg/array-init-2.c') diff --git a/gcc/testsuite/gcc.dg/array-init-2.c b/gcc/testsuite/gcc.dg/array-init-2.c new file mode 100644 index 000000000..9c425818f --- /dev/null +++ b/gcc/testsuite/gcc.dg/array-init-2.c @@ -0,0 +1,51 @@ +/* Test array initializion by store_by_pieces. */ +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +struct A { char c[10]; }; +extern void abort (void); + +void +__attribute__((noinline)) +check (struct A * a, int b) +{ + const char *p; + switch (b) + { + case 0: + p = "abcdefghi"; + break; + case 1: + p = "j\0\0\0\0\0\0\0\0"; + break; + case 2: + p = "kl\0\0\0\0\0\0\0"; + break; + case 3: + p = "mnop\0\0\0\0\0"; + break; + case 4: + p = "qrstuvwx\0"; + break; + default: + abort (); + } + if (__builtin_memcmp (a->c, p, 10) != 0) + abort (); +} + +int +main (void) +{ + struct A a = { "abcdefghi" }; + check (&a, 0); + struct A b = { "j" }; + check (&b, 1); + struct A c = { "kl" }; + check (&c, 2); + struct A d = { "mnop" }; + check (&d, 3); + struct A e = { "qrstuvwx" }; + check (&e, 4); + return 0; +} -- cgit v1.2.3
