RFR(XXL): 8144019: PPC64 C1: Introduce Client Compiler

[Doerr, Martin]

Hi,

I also prefer to push it in one change.
However, we need a sponsor from Oracle.
Can anybody volunteer, please?

The only non-PPC64 file is make/linux/Makefile.
I just removed a small PPC64 part from it which prevented the C1 build.

The remaining files are maintained by us, anyway.

The current webrev is:
http://cr.openjdk.java.net/~mdoerr/8144019_ppc64_c1/webrev.01/

Thanks and best regards,
   Martin

Hi Christian,

I understand we need to follow the rules.
But then I would like to keep it as one change.
That's just cleaner.

Best regards,
  Goetz.

Hi,

could please someone from out of SAP review this?
This being a quite big change I would like to have someone
else to look over it to assure everything is formally correct.

Also, it contains the few lines needed to enable the C1 build on ppc64
in the shared linux makefiles.  May I push this despite this?
Else we would need a sponsor please.

The rules say we have to use JPRT.  We could also split it into two changes and you can push the C1 port directly.  I can piggyback the Makefile change with something else.


Thanks,
  Goetz.

Hi,

we would like to contribute our PPC64 port of the Client Compiler to support Tiered Compilation.
The change includes refactoring of some functionality which is shared between C1 and C2 and some updates.

The webrev is here:
http://cr.openjdk.java.net/~mdoerr/8144019_ppc64_c1/webrev.00

It only changes PPC64 files, with one minor exception: make/linux/Makefile

Please review. I will also need a sponsor, please.

Best regards,
  Martin
