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.
