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/obj-c++.dg/method-conflict-2.mm | 34 +++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 gcc/testsuite/obj-c++.dg/method-conflict-2.mm (limited to 'gcc/testsuite/obj-c++.dg/method-conflict-2.mm') diff --git a/gcc/testsuite/obj-c++.dg/method-conflict-2.mm b/gcc/testsuite/obj-c++.dg/method-conflict-2.mm new file mode 100644 index 000000000..0b0612d77 --- /dev/null +++ b/gcc/testsuite/obj-c++.dg/method-conflict-2.mm @@ -0,0 +1,34 @@ +/* Contributed by Nicola Pero , December 2010. */ +/* { dg-do compile } */ + +#include + +/* Test that you can not declare two methods, in the same protocol, + with the same name and method signature, but one as @required and + once as @optional. */ + +/* First, @required conflicting with @optional. */ +@protocol MyProtocol + +@optional ++ (void) method1: (id)x; /* { dg-message "previous declaration" } */ +- (id) method2: (long)x; /* { dg-message "previous declaration" } */ + +@required ++ (void) method1: (id)x; /* { dg-error "declared .@optional. and .@required. at the same time" } */ +- (id) method2: (long)x; /* { dg-error "declared .@optional. and .@required. at the same time" } */ + +@end + +/* Second, @optional conflicting with @required. */ +@protocol MyProtocol2 + +@required ++ (void) method3: (Class)x; /* { dg-message "previous declaration" } */ +- (id *) method4: (long)x; /* { dg-message "previous declaration" } */ + +@optional ++ (void) method3: (Class)x; /* { dg-error "declared .@optional. and .@required. at the same time" } */ +- (id *) method4: (long)x; /* { dg-error "declared .@optional. and .@required. at the same time" } */ + +@end -- cgit v1.2.3
