Correct webrev link:


Hi Nils,

Indention of changed code is incorrect in compileBroker.cpp.

Output parser should not relay on particular spacing in output. Is it 
hard to fix? I am not comfortable that you changing output of non-tiered 
code just to workaround a problem in a tool.

Do you think we should also test only C1 compilation when Tiered is 

  -XX:+TieredCompilation -XX:TieredStopAtLevel=1
