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/string-opt-17.c | 45 ++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/string-opt-17.c (limited to 'gcc/testsuite/gcc.c-torture/execute/string-opt-17.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/string-opt-17.c b/gcc/testsuite/gcc.c-torture/execute/string-opt-17.c new file mode 100644 index 000000000..76a351bfb --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/string-opt-17.c @@ -0,0 +1,45 @@ +/* Copyright (C) 2003 Free Software Foundation. + + Test strcpy optimizations don't evaluate side-effects twice. + + Written by Jakub Jelinek, June 23, 2003. */ + +typedef __SIZE_TYPE__ size_t; +extern char *strcpy (char *, const char *); +extern int memcmp (const void *, const void *, size_t); +extern void abort (void); +extern void exit (int); + +size_t +test1 (char *s, size_t i) +{ + strcpy (s, "foobarbaz" + i++); + return i; +} + +size_t +check2 (void) +{ + static size_t r = 5; + if (r != 5) + abort (); + return ++r; +} + +void +test2 (char *s) +{ + strcpy (s, "foobarbaz" + check2 ()); +} + +int +main (void) +{ + char buf[10]; + if (test1 (buf, 7) != 8 || memcmp (buf, "az", 3)) + abort (); + test2 (buf); + if (memcmp (buf, "baz", 4)) + abort (); + exit (0); +} -- cgit v1.2.3
