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/memcmp.c | 41 ++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/memcmp.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/memcmp.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/memcmp.c b/gcc/testsuite/gcc.c-torture/execute/builtins/memcmp.c new file mode 100644 index 000000000..5489048f5 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/memcmp.c @@ -0,0 +1,41 @@ +/* Copyright (C) 2001 Free Software Foundation. + + Ensure that short builtin memcmp are optimized and perform correctly. + On architectures with a cmpstrsi instruction, this test doesn't determine + which optimization is being performed, but it does check for correctness. + + Written by Roger Sayle, 12/02/2001. + Additional tests by Roger Sayle after PR 3508, 12/26/2001. */ + +extern void abort (void); +typedef __SIZE_TYPE__ size_t; +extern int memcmp (const void *, const void *, size_t); +extern char *strcpy (char *, const char *); +extern void link_error (void); + +void +main_test (void) +{ + char str[8]; + + strcpy (str, "3141"); + + if ( memcmp (str, str+2, 0) != 0 ) + abort (); + if ( memcmp (str+1, str+3, 0) != 0 ) + abort (); + + if ( memcmp (str+1, str+3, 1) != 0 ) + abort (); + if ( memcmp (str, str+2, 1) >= 0 ) + abort (); + if ( memcmp (str+2, str, 1) <= 0 ) + abort (); + + if (memcmp ("abcd", "efgh", 4) >= 0) + link_error (); + if (memcmp ("abcd", "abcd", 4) != 0) + link_error (); + if (memcmp ("efgh", "abcd", 4) <= 0) + link_error (); +} -- cgit v1.2.3
