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/strings/const-str-5.mm | 28 +++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/obj-c++.dg/strings/const-str-5.mm (limited to 'gcc/testsuite/obj-c++.dg/strings/const-str-5.mm') diff --git a/gcc/testsuite/obj-c++.dg/strings/const-str-5.mm b/gcc/testsuite/obj-c++.dg/strings/const-str-5.mm new file mode 100644 index 000000000..8c12a0c11 --- /dev/null +++ b/gcc/testsuite/obj-c++.dg/strings/const-str-5.mm @@ -0,0 +1,28 @@ +/* Positive test case for constant string layout. */ +/* Contributed by Ziemowit Laski . */ + +/* { dg-do compile } */ +/* { dg-options "-fconstant-string-class=MyConstantString" } */ +/* { dg-options "-mno-constant-cfstrings -fconstant-string-class=MyConstantString" { target *-*-darwin* } } */ + +@interface MyBase { + const char *p; +} +@end + +@interface MyConstantString: MyBase { + union equiv_u { + void *u; + unsigned char *c; + } _contents; + unsigned int _count; +} +@end + +/* The NeXT runtime initializes the 'isa' pointer of string constants at + compile time. */ +#ifdef __NEXT_RUNTIME__ +extern void *_MyConstantStringClassReference; +#endif + +MyConstantString *str = @"Hello"; -- cgit v1.2.3
