2017-10-01	Move out variables from the head of combined instructions	Björn Gustavsson
	Move out from the head the variables that are only used in the excute phase.
2017-10-01	instrs.tab: Add missing -no_next directives	Björn Gustavsson

2017-09-13	Refactor instructions to support relative jumps	Björn Gustavsson
	Introduce new macros that can be used for relative jumps and use them consistently. Test that everything works by using a non-zero constant JUMP_OFFSET. The loader subtracts JUMP_OFFSET from loaded labels, and all instructions that use 'f' operands add it back.
2017-09-11	Avoid using $Src more than once	Björn Gustavsson
	The C compiler will probably optimize this, but just to be sure...
2017-09-04	Don't allow macros to assign to hard-coded variables	Björn Gustavsson
	It's bad style. Pass the name of the variable as an extra argument to the macro.
2017-09-04	Eliminate unecessary instruction macro i_move_call_only()	Björn Gustavsson

2017-08-31	Add missing -no_next directives	Björn Gustavsson

2017-08-31	Eliminate three arguments for the apply() helper	Björn Gustavsson
	We don't need to pass x(0), x(1), and x(2) because they can already be found in the register array.
2017-08-31	Add annotations for likely/unlikely	Björn Gustavsson
	In a correct Erlang programs, we can expect that: * A GC test instruction (such as test_heap) is more likely not to do the GC. * A BIF is more likely to succeed than to fail. * A BIF is more likely to fail in a guard than in a body. * An apply or fun call is likely to succeed. Annotate conditions accordingly.
2017-08-22	Add missing -no_next for badarg instruction	Björn Gustavsson

2017-08-11	Break out most instructions from beam_emu.c	Björn Gustavsson

2017-08-08	Simplify specifying implementation of instructions	Björn Gustavsson
	Eliminate the need to write pre-processor macros for each instruction. Instead allow the implementation of instruction to be written in C directly in the .tab files. Rewrite all existing macros in this way and remove the %macro directive.
