Everybody,
I'd followed common opinion and turn off tracking of variable assignment for vmStructs file only.
Updated webrev is here:

Everybody,
Please review: http://cr.openjdk.java.net/~dsamersoff/JDK-8114853/webrev.01/ Story: VTA fails on huge VMStructs::init() so this method is being compiled twice. VTA[1] allows compiler to emit DWARF-3 debugging information for local variable ever if this variable is optimized out at the cost of compilation time and compiler memory consumption. So I decided to turn it off for entire hotspot build to reduce memory footprint/increase compilation speed. 1. https://gcc.gnu.org/wiki/VarTrackingAssignments -Dmitry
