Subject svn commit: r662811 - in /harmony/enhanced/classlib/trunk: make/ modules/portlib/src/main/native/port/unix/ modules/portlib/src/main/native/port/unix/stubs/
Date Tue, 03 Jun 2008 14:18:42 GMT
Author: hindessm
Date: Tue Jun  3 07:18:42 2008
New Revision: 662811

URL: http://svn.apache.org/viewvc?rev=662811&view=rev
Log:
A number of sets of portlib functions are not actually used (by classlib
today), in order to "lower the bar" for those wishing to do porting work
I've added some trivial stubs for these functions and a -Dhy.portlib.stubs=true
option to enable them.

We might even want to use them to reduce the hyprt dll footprint until
such time as this code is actually used - but this might not please
Ollie who has just written some tests to make sure this unused code
is working. ;-)
