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-array-lval-7.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c99-array-lval-7.c (limited to 'gcc/testsuite/gcc.dg/c99-array-lval-7.c') diff --git a/gcc/testsuite/gcc.dg/c99-array-lval-7.c b/gcc/testsuite/gcc.dg/c99-array-lval-7.c new file mode 100644 index 000000000..3d70ed07b --- /dev/null +++ b/gcc/testsuite/gcc.dg/c99-array-lval-7.c @@ -0,0 +1,21 @@ +/* Test for non-lvalue arrays: test that C90 does not allow them in + conditional expressions, while in C99 they decay and are + allowed. */ + +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1999 -pedantic-errors" } */ + +struct s { char c[1]; }; +struct s a, b, c; +int d; +int e; + +void +bar (void) +{ + /* In C90, the non-lvalue arrays do not decay to pointers, and + 6.3.15 does not permit conditional expressions between arrays. + In C99, they decay to pointers. */ + (e ?
