Building the Hotspot compiler team's Hotspot branch alone

build.sh

#!/bin/sh
# This script is for building the hsx/hotspot-comp branch in isolation.
#
# Prerequisites:
# * appropriate build tools
# * a working Sun Java 6 build (i.e. JDK6) is available at:
#     HOME/java/re/j2se/1.6.0/latest/binaries/linux-[i586/amd64]
# * a working Sun Java 7 build (i.e. JDK7) is available at:
#     HOME/java/re/j2se/1.7.0/latest/binaries/linux-[i586/amd64]
#     HOME/java/re/j2se/1.7.0/promoted/latest/binaries/linux-[i586/amd64]
#     HOME/java/re/jdk/7/latest/binaries/linux-[i586/amd64]
#     (symlinks are ok here)
# * Hotspot compiler team branch checked out:
#     hg clone http://hg.openjdk.java.net/hsx/hotspot-comp/hotspot [dirname]
#
# Usage:
#   (from within checked-out dir)
#   sh ./build.sh help        # for build help
#   sh ./build.sh docs        # run this once before create_jdk
#   sh ./build.sh product     # to build "product" hotspot
#   sh ./build.sh create_jdk  # to create a new jdk based on JDK7 and this build
#   sh ./build.sh update_jdk  # update already-assembled JDK with new hotspot build
# The _jdk targets will deposit a full JDK environment under:
#   build/linux/jdk-linux-[i586/amd64]
