Checkout the C2 branch

  [adinn jdk8]$ hg -R hotspot update -r aarch64_c2

Configure for c2

  [adinn jdk8]$ sh ./configure --with-debug-level=slowdebug
--with-boot-jdk=/usr/lib/jvm/java-1.7.0-openjdk.x86_64
--with-jvm-variants=server --with-sys-root=/
--openjdk-target=aarch64-oe-linux --disable-zip-debug-info

Compile C2

  [adinn jdk8]$ make STRIP_POLICY=no_strip LOG="debug" JOBS=4
BUILTIN_SIM=true CONF=linux-aarch64-normal-server-slowdebug images

Execute with tiered compilation

  [adinn jdk8]$
build/linux-aarch64-normal-server-slowdebug/images/j2sdk-image/bin/java
-server -XX:+TieredCompilation -XComp -XX:CompileThreshold=150
-XX:+CIPrintCompileQueue -XX:+CIPrintRequests -XX:-UseCompressedOops
HelloWorld

You don't actually need to have a HelloWorld.class in your classpath as
you should hit the Unimplemented during bootstrap

n.b. once you have configured
build/linux-aarch64-normal-server-slowdebug your sim_compile script will
no longer know which VM to run. You can either delete the server build
after you finish debugging or else modify sim_compile to include
CONF=linux-aarch64-normal-client-slowdebug
