Subject [jira] Commented: (HARMONY-1005) [classlib] initial port to x86_64 platform
Date Mon, 31 Jul 2006 08:58:14 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1005?page=comments#action_12424500 ] 
Mikhail Fursov commented on HARMONY-1005:

Some comments on 'drlvm_port_patch.txt' patch:

1) Why do we need new UDATA/IDATA defines in header file UDATA stacksize, UDATA priority,
UDATA suspend ?
Looks like all these values could have the same type for any platform

2) I propose not to remove usages of check_available_stack_size() from EM64T version but fix
this method to do nothing if it's not ready for EM64T today.

>                 URL: http://issues.apache.org/jira/browse/HARMONY-1005
>             Project: Harmony
>          Issue Type: Improvement
>          Components: Classlib
>         Environment: Linux, X86_64
>            Reporter: Marina V. Goldburt
>         Attachments: classlib_em64t_patch.txt, drlvm_port_patch.txt
> the classlib_em64t_patch.txt patch allows the classlib to be compiled and run under Linux/x86_64
> the drlvm_port_patch.txt was done only for testing purposes, it allows the DRLVM to be
compiled and run Linux/x86_64 platform in the interpreter mode.
> to test the patch:
> 1. checkout classlib under Linux/x86_64 environment
> 2. apply patch classlib_em64t_patch.txt
> 3. create depends/libs/linux.x86_64 directory 
> 4. build and copy there x86_64 version of icu* libraries
> 5. download dependencies
> 6. build classlib: ant -Dos.arch=x86_64
>     Note: setting os.arch manually is necessary as Ant doesn't set os.arch correctly
> 7. checkout DRLVM
> 8. apply patch  drlvm_port_patch.txt
> 9. change remote.ECLIPSE.location in the build/make/lnx.properties to point it to the
x86_64 eclipse build
>     or set ECLIPSE_HOME to the appropriate location
> 10. build DRLVM
> 11. Run eclipse.sh script under deploy/jre/bin directory to test the build.
> As jitrino doesn't support x86_64 platform, use java -Xint  <some class> to test
