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/strchr.c | 36 ++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/builtins/strchr.c (limited to 'gcc/testsuite/gcc.c-torture/execute/builtins/strchr.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/builtins/strchr.c b/gcc/testsuite/gcc.c-torture/execute/builtins/strchr.c new file mode 100644 index 000000000..08e87c63d --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/builtins/strchr.c @@ -0,0 +1,36 @@ +/* Copyright (C) 2000, 2003 Free Software Foundation. + + Ensure all expected transformations of builtin strchr and index + occur and perform correctly. + + Written by Jakub Jelinek, 11/7/2000. */ + +extern void abort (void); +extern char *strchr (const char *, int); +extern char *index (const char *, int); + +void +main_test (void) +{ + const char *const foo = "hello world"; + + if (strchr (foo, 'x')) + abort (); + if (strchr (foo, 'o') != foo + 4) + abort (); + if (strchr (foo + 5, 'o') != foo + 7) + abort (); + if (strchr (foo, '\0') != foo + 11) + abort (); + /* Test only one instance of index since the code path is the same + as that of strchr. */ + if (index ("hello", 'z') != 0) + abort (); + + /* Test at least one instance of the __builtin_ style.
