RFR (M) Close alignment gaps in InstanceKlass
Summary: moved fields around and some constant fields into ConstantPool This is a simple change except that I moved some constant fields from InstanceKlass into the constant pool so they can be shared read-only in the CDS archive. There are associated repercussions in SA and JVMCI, so please look at these changes. Also moved similarly sized fields together in the class so there's less likelihood of introducing gaps in future InstanceKlass changes.

Re: RFR (M) Close alignment gaps in InstanceKlass
Hi Coleen,
The SA changes look good. BTW, I've already made the
TestIntConstant.java change in the Loom project.
InstanceKlass::_misc_is_unsafe_anonymous was already changed to "8" in
loom. You might want to sync up with Ron to make sure you aren't making
conflicting changes in this area. Your code looks like:
249 enum {
250 _misc_rewritten = 1 << 0, //
methods rewritten.
251 _misc_has_nonstatic_fields = 1 << 1, // for
sizing with UseCompressedOops
252 _misc_should_verify_class = 1 << 2, // allow
caching of preverification
253 _misc_is_unsafe_anonymous = 1 << 3, // has
embedded _unsafe_anonymous_host field
254 _misc_is_contended = 1 << 4, // marked
with contended annotation
Loom looks like:
static const unsigned _misc_kind_field_size = 0;
...
// Start after _misc_kind field.
enum {
_misc_rewritten = 1 <<
(_misc_kind_field_size + 0), // methods rewritten.
_misc_has_nonstatic_fields = 1 <<
(_misc_kind_field_size + 1), // for sizing with UseCompressedOops
_misc_should_verify_class = 1 <<
(_misc_kind_field_size + 2), // allow caching of preverification
_misc_is_unsafe_anonymous = 1 <<
(_misc_kind_field_size + 3), // has embedded _unsafe_anonymous_host field
_misc_is_contended = 1 <<
(_misc_kind_field_size + 4), // marked with contended annotation
...
At the very least this is a merge conflict that loom will need to deal
with and it would help to know about in advance (Alan normally does the
merges).
thanks,
Chris

It looks like there are other changes in loom that motivated changing it
like this. Why is misc_kind_field_size = 0?
Did loom add more misc_flags ? It turns out that there are plenty of
available flags in the access_flags if more are needed.
Thank you for looking at the SA changes.

Actually I just had a look at the loom instanceKlass.hpp and this change
helps that. Loom adds a kind of InstanceKlass, so changed the field to a
u1 as I have done. This will clean up loom too.

Re: RFR (M) Close alignment gaps in InstanceKlass
Hi Coleen. The JVMCI changes look OK. It looks like there is a Graal unittest that covers getSourceFileName, but those tests don't always get run. If it's not too much trouble, could you look into enabling getSourceFileName() testing in test/hotspot/jtreg/compiler/jvmci/jdk.vm.ci.runtime.test/src/jdk/vm/ci/runtime/test/TestResolvedJavaType.java ? It's currently on the "untested" list. thanks, dl On 4/21/20 1:12 PM, coleen.phillim...@oracle.com wrote: Summary: moved fields around and some constant fields into ConstantPool This is a simple change except that I moved some constant fields from InstanceKlass into the constant pool so they can be shared read-only in the CDS archive.

Re: RFR (M) Close alignment gaps in InstanceKlass
Hi Dean, Thank you for looking at the JVMCI changes and the suggestion to add the test. I did this and found a bug. The new test is quite limited because there's no good test to see if a source file name can assertNotNull(type.getSourceFileName()), so I couldn't iterate through the list of loaded classes like the other tests in that file. http://cr.openjdk.java.net/~coleenp/2020/8238048.02.incr/webrev/index.html Thanks, Coleen On 4/21/20 9:51 PM, Dean Long wrote: Hi Coleen.

Re: RFR (M) Close alignment gaps in InstanceKlass
It looks like calling the JVMCI getSourceFileName() on an array would have accessed random memory because it was expecting an InstanceKlass.

It was never called, except when I tried to call it on an array in the

Something else in that file throws JVMCIError with a similar message.
