From 099c60de4033d7b397d4b3fb47f183b52fcba855 Mon Sep 17 00:00:00 2001 From: Sverker Eriksson Date: Thu, 15 Sep 2016 21:21:10 +0200 Subject: erts: Improve hipe load/upgrade/purge machinery A step toward better integration of hipe load and purge Highlights: * code_server no longer needs to call hipe_unified_loader:post_beam_load/1 Instead new internal function hipe_redirect_to_module() is called by loading BIFs to patch native call sites if needed. * hipe_purge_module() is called by erts_internal:purge_module/2 to purge any native code. * struct hipe_mfa_info redesigned and only used for exported functions that are called from or implemented by native code. A list of native call sites (struct hipe_ref) are kept for each hipe_mfa_info. * struct hipe_sdesc used by hipe_find_mfa_from_ra() to build native stack traces. --- bootstrap/lib/kernel/ebin/hipe_unified_loader.beam | Bin 13800 -> 12548 bytes 1 file changed, 0 insertions(+), 0 deletions(-) (limited to 'bootstrap/lib/kernel/ebin/hipe_unified_loader.beam') diff --git a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam index 2e639db331..f560389756 100644 Binary files a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam and b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam differ -- cgit v1.2.3 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. --- bootstrap/lib/kernel/ebin/hipe_unified_loader.beam | Bin 12548 -> 12528 bytes 1 file changed, 0 insertions(+), 0 deletions(-) (limited to 'bootstrap/lib/kernel/ebin/hipe_unified_loader.beam') diff --git a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam index f560389756..9877283cd2 100644 Binary files a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam and b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam differ -- cgit v1.2.3 From 966098ceb9dd9d18e9bcd37cd06b96045903e320 Mon Sep 17 00:00:00 2001 From: Sverker Eriksson Date: Tue, 20 Sep 2016 16:16:50 +0200 Subject: erts: Move new hipe ref and sdesc lists to loader state --- bootstrap/lib/kernel/ebin/hipe_unified_loader.beam | Bin 12528 -> 12596 bytes 1 file changed, 0 insertions(+), 0 deletions(-) (limited to 'bootstrap/lib/kernel/ebin/hipe_unified_loader.beam') diff --git a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam index 9877283cd2..876407a6d6 100644 Binary files a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam and b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam differ -- cgit v1.2.3 From e77d7a8417368617c4c228af9556a7f6a8f3e84c Mon Sep 17 00:00:00 2001 From: Sverker Eriksson Date: Wed, 28 Sep 2016 20:55:40 +0200 Subject: erts: Fix early hipe patch loading by introducing hipe_bifs:commit_patch_load/1 that creates the HipeModule. --- bootstrap/lib/kernel/ebin/hipe_unified_loader.beam | Bin 12596 -> 12624 bytes 1 file changed, 0 insertions(+), 0 deletions(-) (limited to 'bootstrap/lib/kernel/ebin/hipe_unified_loader.beam') diff --git a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam index 876407a6d6..73e95b03c7 100644 Binary files a/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam and b/bootstrap/lib/kernel/ebin/hipe_unified_loader.beam differ -- cgit v1.2.3
