Into this: +%%% +%%% <<0,1,D,_/bits>>=A, +%%% D. +%%% +%%% Which is much faster as it avoids the creation of intermediate terms.

For example, the binary matching +%% instructions are transformed from the optimization-friendly +%% internal format to instruction more similar to the actual BEAM +%% instructions. +%% +%% * Blocks that will need an instruction for allocating a stack frame +%% are annotated with a {frame_size,Size} annotation. +%% +%% * 'copy' instructions are added for all variables that need +%% to be saved to the stack frame. Additional 'copy' instructions +%% can be added as an optimization to reuse y registers (see +%% the copy_retval sub pass). +%% +%% * Each function is annotated with a {register,RegisterMap} +%% annotation that maps each variable to a BEAM register. The linear +%% scan algorithm is used to allocate registers. +%% +%% There are four kind of registers. x, y, fr (floating point register), +%% and z. A variable will be allocated to a z register if it is only +%% used by the instruction following the instruction that defines the +%% the variable. The code generator will typically combine those +%% instructions to a test instruction. z registers are also used for +%% some instructions that don't have a return value. +%% +%% References: +%% +%% [1] H.
