Subject: testsuite, Objective-C : Add initialize method to root class.
X-Git-Tag: basepoints/gcc-12~4466
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=40330e70770d1c42ca51f6d84b70b04537687bc5;p=thirdparty%2Fgcc.git

testsuite, Objective-C : Add initialize method to root class.

Older versions of the runtime don't like it when the root class
has a missing initialize method.  They try to forward to an non-
existent super class resulting in a crash.

TODO: maybe we can diagnose this.

gcc/testsuite/ChangeLog:

	* objc.dg/ivar-scope-4.m: Add inititialize method to the
	root class.
