Well there's the reason (mentioned in my previous mails but not
emphasized). Suppose we have following Makefile:

Target:	Subtarget1 Subtarget2 Subtarget3
	echo "Body of Target is executed"

Subtarget1:
	echo "Body of Subtarget1 is executed"
	exit 0

Subtarget2:
	echo "Body of Subtarget2 is executed"
	exit 1

Subtarget3:
	echo "Body of Subtarget3 is executed"
	exit 0

If you start build by typing "make" it only run the bodies of Subtarget1
and Subtarget2, as usual.

If you start it by "make -k", ALL three subtargets' bodies are executed
BUT the body of Target is not executed due to error in Subtarget2.

Now slightly modified Makefile:

Target:	Subtarget1 Subtarget2 Subtarget3 TargetRealBody

TargetRealBody:
	echo "Body of Target is executed"

Subtarget1:
	echo "Body of Subtarget1 is executed"
	exit 0

Subtarget2:
	echo "Body of Subtarget2 is executed"
	exit 1

Subtarget3:
	echo "Body of Subtarget3 is executed"
	exit 0

Then this Makefile is started by "make -k", ALL subtarget's bodies are
executed AND also body of TargetRealBody is executed. In our real
example it means that summary is always generated even if for example
hotspot regression test(s) fail.
