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/memcpy-1.c | 63 ++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/memcpy-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/memcpy-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/memcpy-1.c b/gcc/testsuite/gcc.c-torture/execute/memcpy-1.c new file mode 100644 index 000000000..684854b66 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/memcpy-1.c @@ -0,0 +1,63 @@ +#include + +#if defined (STACK_SIZE) +#define MEMCPY_SIZE (STACK_SIZE / 3) +#else +#define MEMCPY_SIZE (1 << 17) +#endif + + +void *copy (void *o, const void *i, unsigned l) +{ + return memcpy (o, i, l); +} + +main () +{ + unsigned i; + unsigned char src[MEMCPY_SIZE]; + unsigned char dst[MEMCPY_SIZE]; + + for (i = 0; i < MEMCPY_SIZE; i++) + src[i] = (unsigned char) i, dst[i] = 0; + + (void) memcpy (dst, src, MEMCPY_SIZE / 128); + + for (i = 0; i < MEMCPY_SIZE / 128; i++) + if (dst[i] != (unsigned char) i) + abort (); + + (void) memset (dst, 1, MEMCPY_SIZE / 128); + + for (i = 0; i < MEMCPY_SIZE / 128; i++) + if (dst[i] != 1) + abort (); + + (void) memcpy (dst, src, MEMCPY_SIZE); + + for (i = 0; i < MEMCPY_SIZE; i++) + if (dst[i] != (unsigned char) i) + abort (); + + (void) memset (dst, 0, MEMCPY_SIZE); + + for (i = 0; i < MEMCPY_SIZE; i++) + if (dst[i] != 0) + abort (); + + (void) copy (dst, src, MEMCPY_SIZE / 128); + + for (i = 0; i < MEMCPY_SIZE / 128; i++) + if (dst[i] != (unsigned char) i) + abort (); + + (void) memset (dst, 0, MEMCPY_SIZE); + + (void) copy (dst, src, MEMCPY_SIZE); + + for (i = 0; i < MEMCPY_SIZE; i++) + if (dst[i] != (unsigned char) i) + abort (); + + exit (0); +} -- cgit v1.2.3
