Subject: VMThrowable.java (getStackTrace): Pass trace as-is to modified lookup().
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=84264cb69e412b6626c2b24cd89592220f08474d;p=gcc.git

VMThrowable.java (getStackTrace): Pass trace as-is to modified lookup().

	* java/lang/VMThrowable.java (getStackTrace): Pass trace as-is to
	modified lookup().
	* gnu/gcj/runtime/NameFinder.java (lookup): Change to take in a
	StackTraceElement directly.
	(newElement): New native helper method to create StackTraceElement
	bypassing Java access control.
	(createStackTraceElement): Use newElement() instead of directly
	calling StackTraceElement's constructor.
	* gnu/gcj/runtime/natNameFinder.cc (newElement): New method.
