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/c90-const-expr-10.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c90-const-expr-10.c (limited to 'gcc/testsuite/gcc.dg/c90-const-expr-10.c') diff --git a/gcc/testsuite/gcc.dg/c90-const-expr-10.c b/gcc/testsuite/gcc.dg/c90-const-expr-10.c new file mode 100644 index 000000000..30c60e31f --- /dev/null +++ b/gcc/testsuite/gcc.dg/c90-const-expr-10.c @@ -0,0 +1,30 @@ +/* Test for constant expressions: invalid null pointer constants in + various contexts (make sure NOPs are not inappropriately + stripped). */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1990 -pedantic-errors" } */ + +__extension__ typedef __SIZE_TYPE__ size_t; + +void *p = (size_t)(void *)0; /* { dg-error "without a cast" } */ +struct s { void *a; } q = { (size_t)(void *)0 }; /* { dg-error "without a cast|near initialization" } */ +void * +f (void) +{ + void *r; + r = (size_t)(void *)0; /* { dg-error "without a cast" } */ + return (size_t)(void *)0; /* { dg-error "without a cast" } */ +} +void g (void *); /* { dg-message "but argument is of type" } */ +void +h (void) +{ + g ((size_t)(void *)0); /* { dg-error "without a cast" } */ +} +void g2 (int, void *); /* { dg-message "but argument is of type" } */ +void +h2 (void) +{ + g2 (0, (size_t)(void *)0); /* { dg-error "without a cast" } */ +} -- cgit v1.2.3
