I'm studying H5022 - incorrect codegeneration of compressed obj arithmetics[1]. In my understanding, the problem is that current JIT casts heap base address from 64-bit to 32-bit compulsorily in IA32 but that address must be in 64-bit even in a 32-bit platform. If I catch the point of this jira correctly, I'll try to delete the casts in Ia32InstCodeSelector.cpp recently. Any comment? Thanks.
