Furthermore, all Index -%% values are constant positive integers, and the first call to -%% 'setelement' will have the greatest index. Thus all the following -%% calls do not actually need to test at run-time whether Tuple has type -%% tuple, nor that the index is within the tuple bounds. -%% -%% Since this introduces destructive updates in the Core Erlang code, it -%% must be done as a last stage before going to lower-level code. -%% -%% NOTE: Because there are currently no write barriers in the system, -%% this kind of optimization can only be done when we are sure that -%% garbage collection will not be triggered between the creation of the -%% tuple and the destructive updates - otherwise we might insert -%% pointers from an older generation to a newer. -%% -%% The rewriting is done as follows: -%% -%% let X1 = call 'erlang':'setelement(5, Tuple, Value1) -%% in call 'erlang':'setelement(3, X1, Value2) -%% => -%% let X1 = call 'erlang':'setelement(5, Tuple, Value1) -%% in do primop dsetelement(3, X1, Value2) -%% X1 -%% and -%% let X1 = call 'erlang':'setelement(5, Tuple, Value1) -%% in let X2 = call 'erlang':'setelement(3, X1, Value2) -%% in ... -%% => -%% let X2 = call 'erlang':'setelement(5, Tuple, Value1) -%% in do primop 'dsetelement(3, X2, Value2) -%% ... -%% if X1 is used exactly once. -%% Thus, we need to track variable usage. -%% - --module(sys_core_dsetel). - --export([module/2]). - --include("core_parse.hrl"). - --spec module(cerl:c_module(), [compile:option()]) -> {'ok', cerl:c_module()}. - -module(M0, _Options) -> - M = visit_module(M0), - {ok,M}. - -visit_module(#c_module{defs=Ds0}=R) -> - Env = #{}, - Ds = visit_module_1(Ds0, Env, []), - R#c_module{defs=Ds}. - -visit_module_1([{Name,F0}|Fs], Env, Acc) -> - try visit(Env, F0) of - {F,_} -> - visit_module_1(Fs, Env, [{Name,F}|Acc]) - catch - Class:Error:Stack -> - #c_var{name={Func,Arity}} = Name, - io:fwrite("Function: ~w/~w\n", [Func,Arity]), - erlang:raise(Class, Error, Stack) - end; -visit_module_1([], _, Acc) -> - lists:reverse(Acc). - -visit(Env, #c_var{name={_,_}}=R) -> - %% Ignore local function name. - {R, Env}; -visit(Env0, #c_var{name=X}=R) -> - %% There should not be any free variables.
