	* pan/otp_8332_halfword: Teach testcase in driver_suite the new prototype for driver_async wx: Correct usage of driver callbacks from wx thread Adopt the new (R13B04) Nif functionality to the halfword codebase Support monitoring and demonitoring from driver threads Fix further test-suite problems Correct the VM to work for more test suites Teach {wordsize,internal\|external} to system_info/1 Make tracing and distribution work Turn on instruction packing in the loader and virtual machine Add the BeamInstr data type for loaded BEAM code Fix the BEAM dissambler for the half-word emulator Store pointers to heap data in 32-bit words Add a custom mmap wrapper to force heaps into the lower address range Fit all heap data into the 32-bit address range
2010-03-10	Fit all heap data into the 32-bit address range	Patrik Nyblom
	This is the first step in the implementation of the half-word emulator, a 64-bit emulator where all pointers to heap data will be stored in 32-bit words. Code specific for this emulator variant is conditionally compiled when the HALFWORD_HEAP define has a non-zero value. First force all pointers to heap data to fall into a single 32-bit range, but still store them in 64-bit words. Temporary term data stored on C stack is moved into scheduler specific storage (allocated as heaps) and macros are added to make this happen only in emulators where this is needed. For a vanilla VM the temporary terms are still stored on the C stack.
