Subject [jira] Commented: (HARMONY-3126) [drlvm] VMMagic: migration to new interfaces
Date Thu, 08 Feb 2007 08:12:05 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12471221
] 

Alexey Varlamov commented on HARMONY-3126:
------------------------------------------

Mikhail, I noticed the following issues:
1) Seems that newly exported function "field_is_magic_type_reference()" has no direct use.
The only current usecase is (and I could not invent any other): 
-            if (field_is_reference(fh)) {
+            if (field_is_reference(fh) && !field_is_magic_type_reference(fh)) {
I believe we should just replace  field_is_reference() with field_is_enumerable(), like this:
-            if (field_is_reference(fh)) {
+            if (field_is_enumerable(fh)) {
Or simply change the semantics of field_is_reference() - though this might be confusing in
regards to internal Field API.
2) An assert is commented out in Ia32Inst.cpp due to warning - let's just fix this.

> This patch contains:
> 1) all VMmagics methods updated to use annotations-like pragmas instead of obsolete exception-like
> 2) vmmagic.jar location is updated to point to the new version. Run 'build update' before
building drlvm
> 3) method_has_annotation was added to VM interfaces
> 4) magic types were removed from VM/GC enumeration
> 5) some refactoting was done to simplefy EM64T port (I hope it were all VM/GC changes
needed)
> 6) minor bugfixes and improvements
