System Information
Win7 x64, AMD HD 7770, Catalyst 15.4 beta

Blender Version
Broken: 2.75.5 33a7b72 (after ecd4ee75af)
Worked: 2.75 testbuild1

Short description of error
On HD 7770, most scene are 15% slower with the patch than with the testbuild1, although it should bring better performance (was 25% better with selective nodes compilation from original patch) so in the end it's 35% less performance than original selective nodes compilation implementation.

Exact steps for others to reproduce the error
Render the Barcelona Pavillon from https://www.blender.org/download/demo-files/ with testbuild1 and with latest buildbot.

update: actually with today's build, it is back to testbuild1 speed. Was the patch removed ? Their is really 0 difference between the 2 builds (time memory usage and picture). I also didn't had the bug reported yesterday by some about bump mapping node making black materials. Do wa have to do something to activate selective nodes compilation?

Memory usage is also the same in testbuild1 and latest buildbot. So something makes that the selective node compilation doesn't work.

No, the patch was not removed. Maybe it was the Black Bump Node bug, that has been fixed. Closing as this is resolved, according to your comments.

yes the speed regression is solved, but the fact that the patch should have brought speed enhancement and better memory management is still there. Those enhancement are not there. Should I open a new ticket?
