2016-11-21erts: Mend broken checks in nif_SUITESverker Eriksson
Macro CHECK did not fail the test case just some nice logging that no one saw. One ignored failure fixed; a delayed unload after purge due to live resource with dtor.

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: 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.
2016-10-13Add system_info(atom_limit)Gabriele Santomaggio
Add system_info(atom_limit) to provide a way to retrieve the maximum number of atoms allowed. Add tests and documentation for it too. Also split system_info_SUITE:start_node/2 to start_node_ets/2 and start_node_atm/2 to avoid code duplication.
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.
2016-10-04erts: Do tracer liveness check on current tracerLukas Larsson
This fixes a fault introduced in 19.0 where an invalid tracer would block setting of a new tracer on a process.
2016-09-23Merge branch 'sverker/remove-nif-reload/OTP-13908'Sverker Eriksson
* sverker/remove-nif-reload: erts: Cuddle nif_SUITE:consume_timeslice erts: Remove old doc note for erlang:load_nif erts: Remove deprecated nif 'reload' feature erts: Fix trace_nif_SUITE to load nif lib only once
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.

2016-09-19erts: Remove deprecated nif 'reload' featureSverker Eriksson
and instead let erlang:load_nif/2 return {error, {reload, _}} before even trying to load the library if a NIF library has already been successfully loaded for the calling module instance.

2016-09-05Implement the new ceil/1 and floor/1 guard BIFsBjörn Gustavsson
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of Erlang language). They are guard BIFs because trunc/1 is a guard BIF. It would be strange to have trunc/1 as a part of the language, but not ceil/1 and floor/1.

2016-09-01compiler: Eliminate use of sys_pre_expandBjörn Gustavsson
sys_pre_expand previously did a lot more work, for example, translating records and funs, but now is merely a grab bag of small transformations. Move those transformations to v3_core.
2016-08-31Avoid selective receive in code-purger processRickard Green
The code purger process handles vast amounts of messages when there are lots of processes alive. A single message in the message queue that does not match will in such cases cause lots of extra work. The code purger process now always picks the first message in the message queue, and by this avoid this extra work.
