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/pointer-arith-3.c | 41 ++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pointer-arith-3.c (limited to 'gcc/testsuite/gcc.dg/pointer-arith-3.c') diff --git a/gcc/testsuite/gcc.dg/pointer-arith-3.c b/gcc/testsuite/gcc.dg/pointer-arith-3.c new file mode 100644 index 000000000..bcfb2a4b5 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pointer-arith-3.c @@ -0,0 +1,41 @@ +/* Test diagnostics for arithmetic on void and function pointers. + Test with -pedantic. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-pedantic" } */ + +void *p; +void (*f)(void); + +void +g (void) +{ + p + 0; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p + 1; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + 0 + p; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + 1 + p; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p - 0; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p - 1; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p += 0; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p += 1; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p -= 0; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + p -= 1; /* { dg-warning "pointer of type 'void \\*' used in arithmetic" } */ + f + 0; /* { dg-warning "pointer to a function used in arithmetic" } */ + f + 1; /* { dg-warning "pointer to a function used in arithmetic" } */ + 0 + f; /* { dg-warning "pointer to a function used in arithmetic" } */ + 1 + f; /* { dg-warning "pointer to a function used in arithmetic" } */ + f - 0; /* { dg-warning "pointer to a function used in arithmetic" } */ + f - 1; /* { dg-warning "pointer to a function used in arithmetic" } */ + f += 0; /* { dg-warning "pointer to a function used in arithmetic" } */ + f += 1; /* { dg-warning "pointer to a function used in arithmetic" } */ + f -= 0; /* { dg-warning "pointer to a function used in arithmetic" } */ + f -= 1; /* { dg-warning "pointer to a function used in arithmetic" } */ + p[0]; /* { dg-warning "dereferencing 'void \\*' pointer" } */ + /* { dg-warning "pointer of type 'void \\*' used in arithmetic" "array 1" { target *-*-* } 33 } */ + 0[p]; /* { dg-warning "dereferencing 'void \\*' pointer" } */ + /* { dg-warning "pointer of type 'void \\*' used in arithmetic" "array 1" { target *-*-* } 35 } */ + f[0]; /* { dg-error "subscripted value is pointer to function" } */ + 0[f]; /* { dg-error "subscripted value is pointer to function" } */ + p - p; /* { dg-warning "pointer of type 'void \\*' used in subtraction" } */ + f - f; /* { dg-warning "pointer to a function used in subtraction" } */ +} -- cgit v1.2.3
