From 39072836944d00c288beebfd98b14593f9609006 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Magnus=20L=C3=A5ng?= Date: Thu, 19 May 2016 17:38:54 +0200 Subject: Add a loader state for HiPE code loading Just like the BEAM loader state (as returned by erlang:prepare_loading/2), the HiPE loader state is contained in a magic binary. 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. --- erts/emulator/hipe/hipe_bif0.tab | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'erts/emulator/hipe/hipe_bif0.tab') diff --git a/erts/emulator/hipe/hipe_bif0.tab b/erts/emulator/hipe/hipe_bif0.tab index ff9c1d06fb..1e4bde5ef2 100644 --- a/erts/emulator/hipe/hipe_bif0.tab +++ b/erts/emulator/hipe/hipe_bif0.tab @@ -44,8 +44,8 @@ bif hipe_bifs:ref/1 bif hipe_bifs:ref_get/1 bif hipe_bifs:ref_set/2 -bif hipe_bifs:enter_code/2 -bif hipe_bifs:alloc_data/2 +bif hipe_bifs:enter_code/3 +bif hipe_bifs:alloc_data/3 bif hipe_bifs:constants_size/0 bif hipe_bifs:merge_term/1 @@ -83,6 +83,8 @@ bif hipe_bifs:patch_call/3 bif hipe_bifs:add_ref/2 bif hipe_bifs:remove_refs_from/1 +bif hipe_bifs:alloc_loader_state/1 + # atoms used by add_ref/2 atom call atom load_mfa -- cgit v1.2.3
