Hi everyone,

Sending this to hotspot-dev since it is a GC change but it touches compiler code in macroAssemblersparc.cpp. https://bugs.openjdk.java.net/browse/JDK-8077873 http://cr.openjdk.java.net/~brutisso/8077873/webrev.00/ The develop flag G1SATBPrintStubs prints out the generated assembly for the SATB stubs. This is has been around since G1 was integrated in the the hotspot repo. But it was only ever implemented for Sparc and it looks much like debugging code that has just been left in the code base. I have not heard of anyone using this flag lately so rather than generalizing it to all platforms I propose that we remove it. If we need to debug the SATB write barrier generation we can easily add back similar logging.

looks good.

Thomas
