2014-02-19compiler: Transform list of Args to exact literal typeBjörn-Egil Dahlberg
2014-02-13compiler: Change map instructions for fetching valuesBjörn-Egil Dahlberg
* Combine multiple get values with one instruction * Combine multiple check keys with one instruction
2014-01-28compiler: Implement different instructions for => and :=Björn Gustavsson
2012-10-10Break apart tail-recursive call instructionsBjörn Gustavsson
Somewhat reduce the code bloat by eliminating special cases.
2012-10-10Represent the 'send' instruction as a call_ext/2 instructionBjörn Gustavsson
Somewhat reduce code bloat.
2012-10-10Rewrite select_val and select_tuple_arity to a select instructionBjörn Gustavsson
Eliminate some code bloat.
2012-10-09Rewrite binary creation instructions to bs_init instructionsBjörn Gustavsson
Rewrite the five binary creation instructions to a bs_init instruction, in order to somewhat reduce code bloat.
2012-10-09Rewrite bs_add, bs_utf*_size to BIF instructions in optimizationsBjörn Gustavsson
We can remove some code bloat by handling the special instructions as BIF instructions in the optimization passes. Also note that bs_utf*_size was not handled by beam_utils:check_liveness/3 (meaning the conservative answer instead of the correct answer would be returned).
2012-10-09Rewrite bs_put* instructions to a generic bs_put instructionBjörn Gustavsson
Seven bs_put_* instructions can be combined into one generic bs_put instruction to avoid some code bloat. That will also improve some optimizations (such as beam_trim) that did not handle all bs_put* variants.
2012-10-09Introduce the mandatory beam_a and beam_z passesBjörn Gustavsson
Introduce the mandary beam_a pass that will be run directly after code generation, and the mandatory beam_z pass that will be run just before beam_asm. Since these passes surround the optimizations, beam_a can (for example) do instruction renaming to simplify the optimization passes and beam_z can undo those renamings.
