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.c-torture/execute/builtins/strcpy.c | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/strcpy.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/strcpy.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/strcpy.c b/gcc/testsuite/gcc.c-torture/execute/builtins/strcpy.c new file mode 100644 index 000000000..0ca62b3a2 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/strcpy.c @@ -0,0 +1,41 @@ +/* Copyright (C) 2000 Free Software Foundation. + + Ensure builtin memcpy and strcpy perform correctly. + + Written by Jakub Jelinek, 11/24/2000. */ + +extern void abort (void); +extern char *strcpy (char *, const char *); +typedef __SIZE_TYPE__ size_t; +extern void *memcpy (void *, const void *, size_t); +extern int memcmp (const void *, const void *, size_t); + +char p[32] = ""; + +void +main_test (void) +{ + if (strcpy (p, "abcde") != p || memcmp (p, "abcde", 6)) + abort (); + if (strcpy (p + 16, "vwxyz" + 1) != p + 16 || memcmp (p + 16, "wxyz", 5)) + abort (); + if (strcpy (p + 1, "") != p + 1 || memcmp (p, "a\0cde", 6)) + abort (); + if (strcpy (p + 3, "fghij") != p + 3 || memcmp (p, "a\0cfghij", 9)) + abort (); + if (memcpy (p, "ABCDE", 6) != p || memcmp (p, "ABCDE", 6)) + abort (); + if (memcpy (p + 16, "VWX" + 1, 2) != p + 16 || memcmp (p + 16, "WXyz", 5)) + abort (); + if (memcpy (p + 1, "", 1) != p + 1 || memcmp (p, "A\0CDE", 6)) + abort (); + if (memcpy (p + 3, "FGHI", 4) != p + 3 || memcmp (p, "A\0CFGHIj", 9)) + abort (); + + /* Test at least one instance of the __builtin_ style.
