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/torture/va-arg-25.c | 44 ++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/va-arg-25.c (limited to 'gcc/testsuite/gcc.dg/torture/va-arg-25.c') diff --git a/gcc/testsuite/gcc.dg/torture/va-arg-25.c b/gcc/testsuite/gcc.dg/torture/va-arg-25.c new file mode 100644 index 000000000..8c0da549d --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/va-arg-25.c @@ -0,0 +1,44 @@ +/* Varargs and vectors! */ + +/* { dg-do run } */ +/* { dg-options "-msse" { target { i?86-*-* x86_64-*-* } } } */ +/* { dg-require-effective-target sse_runtime { target { i?86-*-* x86_64-*-* } } } */ +/* { dg-options "-mabi=altivec -maltivec" { target { powerpc-*-* powerpc64-*-* } } } */ +/* { dg-require-effective-target vmx_hw { target { powerpc-*-* powerpc64--*-* } } } */ + +#include +#include +#include + +#define vector __attribute__((vector_size(16))) + +const vector unsigned int v1 = {10,11,12,13}; +const vector unsigned int v2 = {20,21,22,23}; + +void foo(int a, ...) +{ + va_list args; + vector unsigned int v; + + va_start (args, a); + v = va_arg (args, vector unsigned int); + if (a != 1 || memcmp (&v, &v1, sizeof (v)) != 0) + abort (); + a = va_arg (args, int); + if (a != 2) + abort (); + v = va_arg (args, vector unsigned int); + if (memcmp (&v, &v2, sizeof (v)) != 0) + abort (); + va_end (args); +} + +int main(void) +{ +#if INT_MAX == 2147483647 + foo (1, (vector unsigned int){10,11,12,13}, 2, + (vector unsigned int){20,21,22,23}); +#endif + return 0; +} + -- cgit v1.2.3
