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/objc.dg/gnu-api-2-objc_msg_lookup.m | 77 +++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 gcc/testsuite/objc.dg/gnu-api-2-objc_msg_lookup.m (limited to 'gcc/testsuite/objc.dg/gnu-api-2-objc_msg_lookup.m') diff --git a/gcc/testsuite/objc.dg/gnu-api-2-objc_msg_lookup.m b/gcc/testsuite/objc.dg/gnu-api-2-objc_msg_lookup.m new file mode 100644 index 000000000..5751f3fd2 --- /dev/null +++ b/gcc/testsuite/objc.dg/gnu-api-2-objc_msg_lookup.m @@ -0,0 +1,77 @@ +/* Test the Modern GNU Objective-C Runtime API. + + This is test 'objc_msg_lookup', covering objc_msg_lookup(), + objc_msg_lookup_super() and struct objc_super. */ + +/* { dg-do run } */ +/* { dg-skip-if "" { *-*-* } { "-fnext-runtime" } { "" } } */ + +/* To get the modern GNU Objective-C Runtime API, you include + objc/runtime.h. */ +#include + +/* For objc_msg_lookup(), objc_msg_lookup_super() and struct + objc_super. */ +#include + +#include +#include +#include + +@interface MyRootClass +{ Class isa; } ++ alloc; +- init; +- (int) test; +@end + +@implementation MyRootClass ++ alloc { return class_createInstance (self, 0); } +- init { return self; } +- (int) test { return 20; } +@end + +@interface MySubClass : MyRootClass +- (int) test; +@end + +@implementation MySubClass +- (int) test { return 11; } +@end + +int main (int argc, void **args) +{ + /* Functions are tested in alphabetical order. */ + + printf ("Testing objc_msg_lookup ()...\n"); + { + MySubClass *object = [[MySubClass alloc] init]; + int (* test_IMP) (id receiver, SEL selector); + + test_IMP = (int (*)(id, SEL))objc_msg_lookup (object, @selector (test)); + + if (test_IMP (object, @selector (test)) != 11) + abort (); + } + + printf ("Testing objc_msg_lookup_super ()...\n"); + { + MySubClass *object = [[MySubClass alloc] init]; + struct objc_super super = { 0, 0 }; + int (* test_IMP) (id receiver, SEL selector); + + /* Get the implementation of -test for the superclass of object - + as if we were calling [super test] inside a method + implementation of object. */ + super.self = object; + super.super_class = class_getSuperclass (object_getClass (object)); + test_IMP = (int (*)(id, SEL))objc_msg_lookup_super (&super, @selector (test)); + + /* Invoke it.
