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/zero-link-2.m | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 gcc/testsuite/objc.dg/zero-link-2.m (limited to 'gcc/testsuite/objc.dg/zero-link-2.m') diff --git a/gcc/testsuite/objc.dg/zero-link-2.m b/gcc/testsuite/objc.dg/zero-link-2.m new file mode 100644 index 000000000..ff82e5ed6 --- /dev/null +++ b/gcc/testsuite/objc.dg/zero-link-2.m @@ -0,0 +1,29 @@ +/* Check if the '-fno-zero-link' flag correctly _omits_ an objc_getClass() call. */ +/* Contributed by Ziemowit Laski . */ + +/* { dg-do compile { target *-*-darwin* } } */ +/* { dg-skip-if "" { *-*-* } { "-fgnu-runtime" } { "" } } */ +/* { dg-options "-fno-zero-link" } */ + +#include + +extern void abort(void); +#define CHECK_IF(expr) if(!(expr)) abort(); + +@interface Base: Object ++ (int) getValue; +@end + +@implementation Base ++ (int) getValue { return 1593; } +@end + +int main(void) { + int val = [Base getValue]; + CHECK_IF(val == 1593); + return 0; +} + +/* { dg-final { scan-assembler "_OBJC_ClassRefs_0" { target { *-*-darwin* && { ! lp64 } } } } } */ +/* { dg-final { scan-assembler "_OBJC_ClassRef_Base" { target { *-*-darwin* && { lp64 } } } } } */ +/* { dg-final { scan-assembler-not "objc_getClass" } } */ -- cgit v1.2.3
