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++.robertl/eb75.C | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 gcc/testsuite/g++.old-deja/g++.robertl/eb75.C (limited to 'gcc/testsuite/g++.old-deja/g++.robertl/eb75.C') diff --git a/gcc/testsuite/g++.old-deja/g++.robertl/eb75.C b/gcc/testsuite/g++.old-deja/g++.robertl/eb75.C new file mode 100644 index 000000000..c032c2a78 --- /dev/null +++ b/gcc/testsuite/g++.old-deja/g++.robertl/eb75.C @@ -0,0 +1,19 @@ +// { dg-do assemble } +int*& foo (int const *& x) +{ + return const_cast (x); +} + +/* +If the references in this example are changed to pointers (change +all `&''s to `*'), no warnings result. + +I think this is incorrect according to CD2 5.2.11, para 4: + +4 An lvalue of type T1 can be explicitly converted to an lvalue of type + T2 using the cast const_cast (where T1 and T2 are object types) + if a pointer to T1 can be explicitly converted to the type pointer to + T2 using a const_cast.
