2017-04-12erts: Introduce struct binary_internalsSverker Eriksson
to replace macro ERTS_INTERNAL_BINARY_FIELDS as header in Binary and friends.
2017-04-11erts: Init refc=1 in erts_bin_nrml_allocSverker Eriksson
Only term_to_binary needed some extra attention as it used to initialize refc as 0 instead of 1.
2017-04-05erts: Remove hipe_bifs:remove_refs_from/1Sverker Eriksson
which serves no purpose after all the hipe load&purge fixes merged at 32729cab75325de58bf127e6e8836348071b8682
2017-04-04Refactor hipe specific code to use ErtsCodeInfoSverker Eriksson
instead of ugly negative indexing.
2017-03-30Add a missing 0 to an address, which was suspiciously missingKostis Sagonas
2017-03-27Make hipe_bifs:alloc_data/3 pad addr to alignmentMagnus Lång
7814ec18b made hipe_bifs:alloc_data/3 expect alignments greater than 8 from erts_alloc(), which is not something that it guarantees. Fix it up so that it pads the allocation up to the required alignment, in case it does not initially satisfy the alignment requirement.

to long lived, short lived and native stack.

2017-02-19erts: Drop workarounds for ErLLVM w/ LLVM < 3.9Magnus Lång
2017-02-14erts: Add deallocation veto for magic destructorsSverker Eriksson
A magic destructor can return 0 and thereby take control and prolong the lifetime of a magic binary.

OTP-14202 * rickard/binary-refc: Atomic reference count of binaries also in non-SMP Conflicts: erts/emulator/beam/beam_bp.c
2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()

2016-12-06erts: Fix missing HiPE trampolines on armMagnus Lång
8bb80fe76f5b replaced the "__arm__" macro used to test for the arm architecture in hipe_bif0 with the "arm" macro, which is not universally available. As this replacement is not motivated in the commit message, nor replicated in any other file that uses the "__arm__" macro, this seems to be an accident, and this commit reverts the replacement. When compiled in an environment without the "arm" macro, upgrading hipe code would occasionally not patch relocations to the new module due to being out of range for a shortjump, and a trampoline not being provided to do a longjump. Since this type of relocation patches are not expected to be able to fail, there is no error handling, and aside from a "hipe_redirect_to_module: patch failed" message, code upgrade would proceed and lead to various incorrect behaviour.

2016-10-14erts: Remove dead alloc stats in hipe_amd64.cSverker Eriksson
erlang:system_info({allocator, exec_alloc}) have stats if we need it.
2016-10-14erts: Fix bug in stack walk on riscSverker Eriksson
Symptom: Got ra==NULL at nsp==nsp_end when running basic_SUITE:basic_arith on arm why has this not been detected before?
2016-10-14erts: Fix old leak for ppc hipe codeSverker Eriksson
* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_) * Each module has its own trampolines
2016-10-14erts: Fix old leak for arm hipe codeSverker Eriksson
* Use erts_alloc(ERTS_ALC_T_HIPE_EXEC,_) * Each module has its own trampolines * Stubs do not use trampolines, they do their own long jumps.

creation and destruction.
2016-10-14erts: Free hipe_refs and hipe_sdesc of a failed loadSverker Eriksson
2016-10-14erts: Refactor out hipe_purge_refs/sdescSverker Eriksson
from hipe_purge_module.
2016-10-14erts: Refactor hipe_loader_state_dtor into a true destructorSverker Eriksson
that is only called once. Basically switch hipe_free_loader_state and hipe_loader_state_dtor.
2016-10-14hipe,erts: Remove cached fun 'native_address'Sverker Eriksson
Did not work with purge and made worse by new purge strategy. Did yield terrible performance when fun thing is created *before* fun code is loaded. Like when receiving not yet loaded fun from other node. The cached 'native_address' in ErlFunThing will not be updated leading to mode switch and error_handler being called for every call to the fun from native code.
2016-10-14erts: Fix early hipe patch loadingSverker Eriksson
by introducing hipe_bifs:commit_patch_load/1 that creates the HipeModule.
2016-10-14erts: Move new hipe ref and sdesc lists to loader stateSverker Eriksson
2016-10-14erts: Use hipe_free_moduleSverker Eriksson
2016-10-14erts: Check hipe stack in check_process_codeMagnus Lång
This is part of commit 1bd508921dd93086b05e7d0038b816b36c421d86. I did not include the fun-checking as we have a new purge strategy for funs in OTP 20. That remains to be solved some other way for hipe.
2016-10-14Add a loader state for HiPE code loadingMagnus Lång
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.
2016-10-12erts: Refactor find_function_from_pc to return MFALukas Larsson
2016-10-12erts: Refactor out func_info into structLukas Larsson
This commit adds two new structs to be used to represent erlang code in erts. ErtsCodeInfo is used to describe the i_func_info header that is part of all Export entries and the prelude of each function. This replaces all the BeamInstr * that were previously used to point to these locations. After this change the code should never use BeamInstr * with offsets to figure out different parts of the func_info header. ErtsCodeMFA is a struct that is used to descripe a MFA in code. It is used within ErtsCodeInfo and also in Process->current. All function that previously took Eterm * or BeamInstr * to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo where appropriate. The code has been tested to work when adding a new field to the ErtsCodeInfo struct, but some updates are needed in ops.tab to make it work.
2016-10-10erts: Remove unused hipe_bifs:code_sizeSverker Eriksson
and hipe_bifs:update_code_size
2016-10-10erts: Improve hipe load/upgrade/purge machinerySverker Eriksson
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.
