Build hotspot only in IcedTea after a complete build.

[Nagy Mostafa]

So I read the instructions on Volker's blog (
http://weblogs.java.net/blog/simonis/archive/2008/01/hotspot_develop.html#HotSpotBuild)
and I managed to build hotspot only successfully. The problem now is
enabling Zero. I am running on AMD64 and the build fail with CC_INTERP=1.
Why does this happen and why is Zero built correctly when I do a full build
of IcedTea ?

Anyway to enable Zero on AMD64 when building hotspot only ? The command I
use is:

CC_INTERP=true LP64=1 LANG=C ALT_BOOTDIR=/usr/lib/jvm/java-6-sun/
HOTSPOT_BUILD_JOBS=5 ALT_OUTPUT_DIR=../../build/hotspot-debug make jvmg

The build error is:
/home/nagy/research/icedtea6-debug/openjdk/hotspot/src/cpu/x86/vm/bytecodeInterpreter_x86.hpp:

SharedRuntime::generate_deopt_blob()':
