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/c99-const-expr-9.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c99-const-expr-9.c (limited to 'gcc/testsuite/gcc.dg/c99-const-expr-9.c') diff --git a/gcc/testsuite/gcc.dg/c99-const-expr-9.c b/gcc/testsuite/gcc.dg/c99-const-expr-9.c new file mode 100644 index 000000000..48f43edec --- /dev/null +++ b/gcc/testsuite/gcc.dg/c99-const-expr-9.c @@ -0,0 +1,26 @@ +/* Test for constant expressions: __builtin_offsetof allowed in + integer constant expressions but not traditional offsetof + expansion. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1999 -pedantic-errors" } */ + +struct s { + int a; +}; + +struct t { + struct s a; + int b[2]; +}; + +#define old_offsetof(TYPE, MEMBER) ((__SIZE_TYPE__) &((TYPE *)0)->MEMBER) + +enum e { + E1 = old_offsetof (struct s, a), /* { dg-error "constant" } */ + E2 = old_offsetof (struct t, a.a), /* { dg-error "constant" } */ + E3 = old_offsetof (struct t, b[1]), /* { dg-error "constant" } */ + E4 = __builtin_offsetof (struct s, a), + E5 = __builtin_offsetof (struct t, a.a), + E6 = __builtin_offsetof (struct t, b[1]) +}; -- cgit v1.2.3
