bool Global_Env.use_common_jar_cache

If set to true, DLRVM will store JARs which are adjacent in boot class path into single jar entry cache.

This will optimize lookups on class loading with bootstrap class loader.

bool Global_Env.compact_fields

If set to true by the -compact_fields command-line option, the VM will not pad out fields of less than 32 bits to four bytes.

However, fields will still be aligned to a natural boundary, and the num_field_padding_bytes field will reflect those alignment padding bytes.

bool Global_Env.sort_fields

If set to true by the -sort_fields command line option, the VM will sort fields by size before assigning their offset during class preparation.

Byte* Global_Env.heap_base

Note:

We assume Java heap uses one continuous memory block.
