[jira] Updated: (HARMONY-5037) [drlvm][jit][opt] improper opcode
group lookup
[ https://issues.apache.org/jira/browse/HARMONY-5037?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexey Varlamov updated HARMONY-5037:
-------------------------------------
Attachment: enc64.diff
An updated patch: includes fixes for x86-64 platform.
George, I had to revert that workaround with Boolean size - in fact it is 8 bits in heap and AFAIU we have no other uses for this type.
Remained problem is with spillgen, it fails to handle some operands (assert(fails == 0); at vm\jitrino\src\codegenerator\ia32\Ia32SpillGen.cpp:669). Fortunately turning off global regalloc helps to bypass the issue and almost all tests and scenarios work.
