2016-10-14erts: Remove code_SUITE:make_stub and make_stub_many_funsSverker Eriksson
Hard to unit test now when it takes a magic HipeLoaderState as argument. All hipe testing should be enough exercise for code:make_stub_module.
2016-10-14erts: Let code:make_stub_module raise 'notsup'Sverker Eriksson
if hipe is disabled. Makes the code simpler to just ifdef away a lot of hipe stuff.
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.
2016-10-14erts: Fix old leak of sparc hipe codeSverker Eriksson
2016-10-14erts: Fix old leak of hipe code on x86 32-bitSverker Eriksson
2016-10-14erts: Enable exec_alloc for all hipe architecturesSverker Eriksson
For non-amd64 it's a "normal" allocator with a wrapper around mseg_alloc to call mprotect(PROT_EXEC).
2016-10-14erts: Remove debug printout for hipe loader stateSverker Eriksson
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: Fill freed EXEC memory with illegal instructions on DEBUGSverker Eriksson
to get a nice SIGILL crash. For x86 and x86_64 only.
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.
2016-10-10erts: 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.
2016-10-10erts: Refactor module_start_stagingSverker Eriksson
with a copy_module() function.

2016-09-19Use more correct delimiters for erl_nif.h includeTuncer Ayaz
Anywhere but the beam sources we shouldn't #include "erl_nif.h", because what "erl_nif.h" does is: (1) fail to find it outside of -I dirs, (2) then treat it as if it was written like <erl_nif.h>. Using <erl_nif.h> skips (1). More information can be found in 6.10.2 of the C standard. Because the examples use "erl_nif.h", NIF projects in the Erlang ecosystem copy this verbatim and make the same mistake.
