trouble building mlvm

[Iulian Dragos]

I'm trying to build a version of JDK7 with invoke dynamic support. So
far, I managed to build the 'base' jdk7, but had no success applying
the required patches to get mlvm. I've been trying for 2 days before
giving up and seeking help.

I followed the instructions found in the patches/README file. The
applied patches fail:

dragos at lamppc8 OpenJDK $ sh patches/make/each-patch-repo.sh hg qpush -a
+ (cd sources/hotspot; hg qpush -a)
patch series already fully applied
+ (cd sources/jdk; hg qpush -a)
patch series already fully applied
+ (cd sources/langtools; hg qpush -a)

What's more, none of the patches that are reported as 'already
applied' are actually applied. For instance, looking for
'CallSite.java' in the jdk repository yields nothing.

So I changed the guards to be more permissive (the current release is
jdk7-b41, but patches expect b34 or b38), and I added more tags using
qselect. This triggers patches under jdk/ and they actually succeed.
Unfortunately, the patches under hotspot/ fail miserably:

dragos at lamppc8 hotspot $ hg qpush -a

BTW, in the build instructions, these are the only directories that
appear as being 'patchable'. However, running
patches/make/each-patch-repo.sh touches a third one: langtools. Are
the instructions outdated, or langtools shouldn't be touched?

Thanks for any help,
Iulian
PS. I am a complete novice in Mercurial.
