[jira] Created: (HARMONY-1005) [classlib] initial port to x86_64 platform

[classlib] initial port to x86_64 platform
------------------------------------------

                 Key: HARMONY-1005
                 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 platform.

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 it.

[jira] Commented: (HARMONY-1005) [classlib] initial port to x86_64 platform

Marina V. Goldburt commented on HARMONY-1005:
---------------------------------------------

the 'drlvm_port_patch.txt' was done only for testing purposes,
I don't propose it to be commited. Of course, DRLV porting has to be done more carefully and correctly.

[jira] Commented: (HARMONY-1005) [classlib] initial port to x86_64 platform

Posted by "Mikhail Fursov (JIRA)" <ji...@apache.org>.
    [ 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.
