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.dg/fixed-point/func-vararg-size0.c | 46 ++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/fixed-point/func-vararg-size0.c (limited to 'gcc/testsuite/gcc.dg/fixed-point/func-vararg-size0.c') diff --git a/gcc/testsuite/gcc.dg/fixed-point/func-vararg-size0.c b/gcc/testsuite/gcc.dg/fixed-point/func-vararg-size0.c new file mode 100644 index 000000000..7c54e91b2 --- /dev/null +++ b/gcc/testsuite/gcc.dg/fixed-point/func-vararg-size0.c @@ -0,0 +1,46 @@ +/* { dg-do run } */ +/* { dg-options "-std=gnu99" } */ + +/* C99 6.5.2.2 Function calls. + Based on the test from ../dfp/. */ + +#include + +extern void abort (void); + +struct S1 +{ + struct + { + _Fract e; + } b[0]; +}; + +/* Test handling vararg parameters whose size is 0. */ + +int check_var(int z,...) +{ + double d; + struct S1 s1; + long long result; + va_list ap; + va_start (ap, z); + d = va_arg (ap, double); + s1 = va_arg (ap, struct S1); + result = va_arg (ap, long long); + va_end (ap); + return (result == 2LL); + +} + +int +main () +{ + struct S1 s1; + struct S1 a1[5]; + + if (check_var(5, 1.0, s1, 2LL, a1[2], a1[2]) == 0) + abort (); + + return 0; +} -- cgit v1.2.3
