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/g++.old-deja/g++.ext/namedret2.C | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.ext/namedret2.C (limited to 'gcc/testsuite/g++.old-deja/g++.ext/namedret2.C') diff --git a/gcc/testsuite/g++.old-deja/g++.ext/namedret2.C b/gcc/testsuite/g++.old-deja/g++.ext/namedret2.C new file mode 100644 index 000000000..339fc11e2 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.ext/namedret2.C @@ -0,0 +1,20 @@ +// { dg-do assemble { target alpha*-*-* } } +// { dg-options "-Wno-deprecated" } + +// This test verifies that return type promotion is working correctly. +// The Alpha ABI specifies that 32-bit return values have bit 31 propagated, +// i.e. the value is sign-extended even if the unpromoted type is unsigned. + +unsigned int f(unsigned int x) return y(x) { } // { dg-error "" } + +extern "C" void abort (); + +int main() +{ + typedef long (*long_func)(long); + long_func g = reinterpret_cast(f); + + if (g(-1L) != -1L) + abort (); + return 0; +} -- cgit v1.2.3
