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/memchr.c | 38 ++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/memchr.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/memchr.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/memchr.c b/gcc/testsuite/gcc.c-torture/execute/builtins/memchr.c new file mode 100644 index 000000000..88e731128 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/memchr.c @@ -0,0 +1,38 @@ +/* Copyright (C) 2007 Free Software Foundation. + + Ensure all expected transformations of builtin memchr occur + and perform correctly. + + Written by Paolo Carlini, 10/5/2007. */ + +extern void abort (void); +typedef __SIZE_TYPE__ size_t; +extern void *memchr (const void *, int, size_t); + +void +main_test (void) +{ + const char* const foo1 = "hello world"; + + if (memchr (foo1, 'x', 11)) + abort (); + if (memchr (foo1, 'o', 11) != foo1 + 4) + abort (); + if (memchr (foo1, 'w', 2)) + abort (); + if (memchr (foo1 + 5, 'o', 6) != foo1 + 7) + abort (); + if (memchr (foo1, 'd', 11) != foo1 + 10) + abort (); + if (memchr (foo1, 'd', 10)) + abort (); + if (memchr (foo1, '\0', 11)) + abort (); + if (memchr (foo1, '\0', 12) != foo1 + 11) + abort (); + + /* Test at least one instance of the __builtin_ style.
