build error

[Venkatachalam, Vasanth]

Hi Thomas,

Thanks for the fast response. I checked out the latest copy of the repo and am able to build the code.

What I would like to do now is run a small Java program (say one that just adds two integers) and see PTX code being emitted for the addition.

You mention that you're refactoring the backend. Is the code that I've checked out currently in a state where I will be able to do the above?
If so, can you provide some details on what I need to do to get there?

Thanks,
Vasanth

Vasanth,

I've just pushed a new version to http://hg.openjdk.java.net/graal/graal/ that contains Christian's changes provisionally integrated. You should be able to pull and build. I'm currently working on refactoring our backend to fit the needs of PTX in terms of register allocation and assembly output.

Hi,

I'm trying to build the following patch which adds PTX ISA support to GRAAL.

http://cr.openjdk.java.net/~twisti/0000000/

I applied the patch successfully, but when I tried to build it (using mx build) I got errors such as:




AbstractPTXAssembler.java: 27: error: package com.oracle.graal.lir.ptx


does not exist



Import com.oracle.graal.lir.ptx.*






Apparently the build process is not able to find the above package in question, even though it has been added to the source tree (as a result of applying this patch). It looks like the build scripts may need to be updated so that they know where to find the source file for the above newly added package.

Can someone explain what configuration change needs to be made here so that I will  be able to do an mx build?
