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-bi.c | 53 +++++++++++++++++++++++++ 1 file changed, 53 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/memcpy-bi.c (limited to 'gcc/testsuite/gcc.c-torture/execute/memcpy-bi.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/memcpy-bi.c b/gcc/testsuite/gcc.c-torture/execute/memcpy-bi.c new file mode 100644 index 000000000..40b103080 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/memcpy-bi.c @@ -0,0 +1,53 @@ +/* Test builtin-memcpy (which may emit different code for different N). */ +#include + +#define TESTSIZE 80 + +char src[TESTSIZE] __attribute__ ((aligned)); +char dst[TESTSIZE] __attribute__ ((aligned)); + +void +check (char *test, char *match, int n) +{ + if (memcmp (test, match, n)) + abort (); +} + +#define TN(n) \ +{ memset (dst, 0, n); memcpy (dst, src, n); check (dst, src, n); } +#define T(n) \ +TN (n) \ +TN ((n) + 1) \ +TN ((n) + 2) \ +TN ((n) + 3) + +main () +{ + int i,j; + + for (i = 0; i < sizeof (src); ++i) + src[i] = 'a' + i % 26; + + T (0); + T (4); + T (8); + T (12); + T (16); + T (20); + T (24); + T (28); + T (32); + T (36); + T (40); + T (44); + T (48); + T (52); + T (56); + T (60); + T (64); + T (68); + T (72); + T (76); + + return 0; +} -- cgit v1.2.3
