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++.dg/init/init-ref1.C | 45 +++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 gcc/testsuite/g++.dg/init/init-ref1.C (limited to 'gcc/testsuite/g++.dg/init/init-ref1.C') diff --git a/gcc/testsuite/g++.dg/init/init-ref1.C b/gcc/testsuite/g++.dg/init/init-ref1.C new file mode 100644 index 000000000..d0170cd18 --- /dev/null +++ b/gcc/testsuite/g++.dg/init/init-ref1.C @@ -0,0 +1,45 @@ +// Submitted by Erik Rozendaal +// Test case for GNATS bug 787. +// { dg-do run } + +#include +#include + +static int calls; + +int &foo (int &arg) +{ + calls++; + arg=0; + return arg; +} + +int &identity (int &x) +{ + return x; +} + +int main() +{ + int a; + + calls = 0; + int &b = ++foo (a); + if (calls > 1) + abort (); + if (&a != &b) + abort (); + if (a != 1) + abort (); + + calls = 0; + int &c = ++identity (++foo (a)); + if (calls > 1) + abort (); + if (&a != &c) + abort (); + if (a != 2) + abort (); + + exit (0); +} -- cgit v1.2.3
