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/testsuite/gcc.dg/cpp/strify2.c | 56 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/cpp/strify2.c (limited to 'gcc/testsuite/gcc.dg/cpp/strify2.c') diff --git a/gcc/testsuite/gcc.dg/cpp/strify2.c b/gcc/testsuite/gcc.dg/cpp/strify2.c new file mode 100644 index 000000000..c24220c70 --- /dev/null +++ b/gcc/testsuite/gcc.dg/cpp/strify2.c @@ -0,0 +1,56 @@ +/* Copyright (C) 2000 Free Software Foundation, Inc. */ + +/* { dg-do run } */ +/* { dg-options "-std=c99 -pedantic-errors" } */ + +/* Tests a whole bunch of things are correctly stringified. */ + +extern int strcmp (const char *, const char *); +extern int puts (const char *); +extern void abort (void); +#define err(str) do { puts(str); abort(); } while (0) + +#define str(x) #x +#define xstr(x) str(x) +#define strvar(...) #__VA_ARGS__ + +#define glibc_str(x) glibc_str2 (w, x) +#define glibc_str2(w, x) #x +#define ver GLIBC_2.2 + +int main (int argc, char *argv[]) +{ + str (\); /* { dg-warning "valid string" "str(\\)" } */ + str (\\); /* OK. */ + str (\\\); /* { dg-warning "valid string" "str(\\\\\\)" } */ + + /* This also serves as a useful test of the value of __INCLUDE_LEVEL. */ + if (strcmp (xstr (__INCLUDE_LEVEL__), "0")) + err ("macro expansion"); + + if (strcmp(str (__INCLUDE_LEVEL__), "__INCLUDE_LEVEL__")) + err ("macro name"); + + if (strcmp(str(), "") || strcmp(str( ), "")) + err ("empty string"); + + if (strcmp(str ("s\n"), "\"s\\n\"")) + err ("quoted string"); + + if (strcmp (str (a € b), "a \200 b")) + err ("unprintable char"); + + if (strcmp (str ( a b@ c ), "a b@ c")) + err ("internal whitespace"); + + if (strcmp (str(a \n), "a \n")) + err ("backslash token"); + + if (strcmp (strvar (foo, bar), "foo, bar")) + err ("variable arguments"); + + if (strcmp (glibc_str (ver), "GLIBC_2.2")) + err ("whitespace"); + + return 0; +} -- cgit v1.2.3
