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/vla-14.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vla-14.c (limited to 'gcc/testsuite/gcc.dg/vla-14.c') diff --git a/gcc/testsuite/gcc.dg/vla-14.c b/gcc/testsuite/gcc.dg/vla-14.c new file mode 100644 index 000000000..3dbb11ed1 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vla-14.c @@ -0,0 +1,33 @@ +/* Test for VLA size evaluation in va_arg. */ +/* Origin: Joseph Myers */ +/* { dg-do run } */ +/* { dg-options "-std=gnu99" } */ + +#include + +extern void exit (int); +extern void abort (void); + +int a[10]; +int i = 9; + +void +f (int n, ...) +{ + va_list ap; + void *p; + va_start (ap, n); + p = va_arg (ap, typeof (int (*)[++i])); + if (p != a) + abort (); + if (i != n) + abort (); + va_end (ap); +} + +int +main (void) +{ + f (10, &a); + exit (0); +} -- cgit v1.2.3
