Eventually, we will separate HiPE loading into a prepare and a finalise phase, like the BEAM loader, where the prepare phase will be implemented by hipe_unified_loader and the finalise phase be implemented in C by hipe_load.c and beam_load.c, making prepare side-effect free and finalise atomic. The finalise phase will be exposed through the erlang:finish_loading/1 API, just like the BEAM loader, as this will allow HiPE and BEAM modules to be mixed in the same atomic "commit". The usage of a loader state makes it easier to keep track of all resources allocated during loading, and will not only make it easy to prevent leaks when hipe_unified_loader crashes, but also paves the way for proper, leak-free, unloading of HiPE modules. --- lib/hipe/cerl/erl_bif_types.erl | 21 +++++++++++++-------- 1 file changed, 13 insertions(+), 8 deletions(-) (limited to 'lib/hipe/cerl') diff --git a/lib/hipe/cerl/erl_bif_types.erl b/lib/hipe/cerl/erl_bif_types.erl index 3e5d8e7b90..9a08305686 100644 --- a/lib/hipe/cerl/erl_bif_types.erl +++ b/lib/hipe/cerl/erl_bif_types.erl @@ -1004,8 +1004,8 @@ type(erlang, tuple_to_list, 1, Xs, Opaques) -> %%-- hipe_bifs ---------------------------------------------------------------- type(hipe_bifs, add_ref, 2, Xs, Opaques) -> strict(hipe_bifs, add_ref, 2, Xs, fun (_) -> t_nil() end, Opaques);

For tuples we have `element/2` and for lists `hd/1` and `tl/1`. Maps are completely opaque to guards. This means matching on maps can't be abstracted into macros, which is often done with repetitive guards. It also means that maps have to be always selected whole from ETS tables, even when only one field would be enough, which creates a potential efficiency issue. This PR introduces an `erlang:map_get/2` guard-safe function that allows extracting a map field in guard. An alternative to this function would be to introduce the syntax for extracting a value from a map that was planned in the original EEP: `Map#{Key}`. Even outside of guards, since this function is a guard-BIF it is more efficient than using `maps:get/2` (since it does not need to set up the stack), and more convenient from pattern matching on the map (compare: `#{key := Value} = Map, Value` to `map_get(key, Map)`). Performance considerations A common concern against adding this function is the notion that "guards have to be fast" and ideally execute in constant time. While there are some counterexamples (`length/1`), what is more important is the fact that adding those functions does not change in any way the time complexity of pattern matching - it's already possible to match on map fields today directly in patterns - adding this ability to guards will niether slow down or speed up the execution, it will only make certain programs more convenient to write. This first version is very naive and does not perform any optimizations. --- lib/hipe/cerl/erl_bif_types.erl | 6 ++++++ lib/hipe/cerl/erl_types.erl | 2 +- 2 files changed, 7 insertions(+), 1 deletion(-) (limited to 'lib/hipe/cerl') diff --git a/lib/hipe/cerl/erl_bif_types.erl b/lib/hipe/cerl/erl_bif_types.erl index bfffb8db41..fe6ab0659c 100644 --- a/lib/hipe/cerl/erl_bif_types.erl +++ b/lib/hipe/cerl/erl_bif_types.erl @@ -770,6 +770,9 @@ type(erlang, length, 1, Xs, Opaques) -> %% Guard bif, needs to be here. type(erlang, map_size, 1, Xs, Opaques) -> type(maps, size, 1, Xs, Opaques); +%% Guard bif, needs to be here. +type(erlang, map_get, 2, Xs, Opaques) -> + type(maps, get, 2, Xs, Opaques); type(erlang, make_fun, 3, Xs, Opaques) -> strict(erlang, make_fun, 3, Xs, fun ([_, _, Arity]) -> @@ -2391,6 +2394,9 @@ arg_types(erlang, length, 1) -> %% Guard bif, needs to be here. arg_types(erlang, map_size, 1) -> [t_map()]; +%% Guard bif, needs to be here. +arg_types(erlang, map_get, 2) -> + [t_map(), t_any()]; arg_types(erlang, make_fun, 3) -> [t_atom(), t_atom(), t_arity()]; arg_types(erlang, make_tuple, 2) -> diff --git a/lib/hipe/cerl/erl_types.erl b/lib/hipe/cerl/erl_types.erl index 8a609ef911..a91da97f93 100644 --- a/lib/hipe/cerl/erl_types.erl +++ b/lib/hipe/cerl/erl_types.erl @@ -217,7 +217,7 @@ ]). %%-define(DO_ERL_TYPES_TEST, true). --compile({no_auto_import,[min/2,max/2]}). +-compile({no_auto_import,[min/2,max/2,map_get/2]}). -ifdef(DO_ERL_TYPES_TEST). -export([test/0]). -- cgit v1.2.3 From e92eb8f4bd35c603b5a1b4c24beca01c93d17fe8 Mon Sep 17 00:00:00 2001 From: Sean Cribbs Date: Tue, 3 Apr 2018 11:01:42 -0500 Subject: Move erl_types test into a common_test suite The existing test/0 function in erl_types was not being run in the OTP test suite, and it had not been updated to match the implementation in the module (maps vs. dict).

Rationale. `map_get/2` allows accessing map fields in guards, but it might be problematic in more complex guard expressions, for example: foo(X) when map_get(a, X) =:= 1 or is_list(X) -> ... The `is_list/1` part of the guard could never succeed since the `map_get/2` guard would fail the whole guard expression. In this situation, this could be solved by using `;` instead of `or` to separate the guards, but it is not possible in every case. To solve this situation, this PR proposes a `is_map_key/2` guard that allows to check if a map has key inside a guard before trying to access that key. When combined with `is_map/1` this allows to construct a purely boolean guard expression testing a value of a key in a map. Implementation. Given the use case motivating the introduction of this function, the PR contains compiler optimisations that produce optimial code for the following guard expression: foo(X) when is_map(X) and is_map_key(a, X) and map_get(a, X) =:= 1 -> ok; foo(_) -> error. Given all three tests share the failure label, the `is_map_key/2` and `is_map/2` tests are optimised away. As with `map_get/2` the `is_map_key/2` BIF is allowed in match specs. --- lib/hipe/cerl/erl_bif_types.erl | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'lib/hipe/cerl') diff --git a/lib/hipe/cerl/erl_bif_types.erl b/lib/hipe/cerl/erl_bif_types.erl index fe6ab0659c..48ce641ab9 100644 --- a/lib/hipe/cerl/erl_bif_types.erl +++ b/lib/hipe/cerl/erl_bif_types.erl @@ -665,6 +665,8 @@ type(erlang, is_map, 1, Xs, Opaques) -> check_guard(X, fun (Y) -> t_is_map(Y, Opaques) end, t_map(), Opaques) end, strict(erlang, is_map, 1, Xs, Fun, Opaques); +type(erlang, is_map_key, 2, Xs, Opaques) -> + type(maps, is_key, 2, Xs, Opaques); type(erlang, is_number, 1, Xs, Opaques) -> Fun = fun (X) -> check_guard(X, fun (Y) -> t_is_number(Y, Opaques) end, @@ -2374,6 +2376,8 @@ arg_types(erlang, is_list, 1) -> [t_any()]; arg_types(erlang, is_map, 1) -> [t_any()]; +arg_types(erlang, is_map_key, 2) -> + [t_any(), t_map()]; arg_types(erlang, is_number, 1) -> [t_any()]; arg_types(erlang, is_pid, 1) -> @@ -2396,7 +2400,7 @@ arg_types(erlang, map_size, 1) -> [t_map()]; %% Guard bif, needs to be here. arg_types(erlang, map_get, 2) -> - [t_map(), t_any()]; + [t_any(), t_map()]; arg_types(erlang, make_fun, 3) -> [t_atom(), t_atom(), t_arity()]; arg_types(erlang, make_tuple, 2) -> -- cgit v1.2.3 From 5ca92e2eac1e84fd22f60e7abc3aa2b0ff1cb42b Mon Sep 17 00:00:00 2001 From: Henrik Nord Date: Mon, 18 Jun 2018 14:51:18 +0200 Subject: Update copyright year --- lib/hipe/cerl/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/hipe/cerl') diff --git a/lib/hipe/cerl/Makefile b/lib/hipe/cerl/Makefile index b6116c4276..f653dce36f 100644 --- a/lib/hipe/cerl/Makefile +++ b/lib/hipe/cerl/Makefile @@ -1,7 +1,7 @@ # # %CopyrightBegin% # -# Copyright Ericsson AB 2003-2016.
