* erts: Share printable_return_address with erl_bif_infoJohn Högberg2019-09-164-37/+9

* erts: Let call_bif/call_nif take arguments instead of hardcoding themJohn Högberg2019-09-168-23/+26
|
* erts: Use local trap exports for list functionsJohn Högberg2019-09-164-15/+59
| | | | | | | | | This prevents trapping from showing up in tracing, fixing certain tests that assume the old and erroneous trace behavior for BIFs. Note that this does not fix bogus arguments showing up on exceptions as many of these functions still pass the remainder of of the list to themselves when trapping.

* erts: Rename NifExport to ErtsNativeFuncJohn Högberg2019-09-1611-135/+138
| | | | | All it does is wrap a native function for scheduling, and it no longer has anything to do with exports.

* erts: Refactor BIF tracingJohn Högberg2019-09-1627-1078/+731
| | | | | | | | | | | | | | | This commit replaces our current BIF-specific tracing functionality with the general function/export tracing used for everything else, fixing a few longstanding issues: * BIFs that trapped to themselves, for example lists:reverse/2, would generate a call trace message for each trap but only a single return trace message. * BIFs that trapped elsewhere, like erlang:delete_module/1, would lose their return trace messages altogether. * Return/exception trace messages on tail calls would point at the function "above" the caller. * Call count tracing simply didn't work.
* erts: Replace ad-hoc export->beam[] wrangling with unionsJohn Högberg2019-09-1611-143/+227

* erts: Fix undefined behavior in $DISPATCHX()John Högberg2019-09-116-167/+137
| | | | | | | | | | | | | | | | Some call instructions kept the export entry outside of Arg(0) for better argument packing, so the $DISPATCHX() macro faked a new instruction pointer starting at "one behind" the given argument. Some of these saved the argument on the C stack and passed that onwards to this macro, which could provoke undefined behavior if we were to jump out of the block, for example if we needed to save_calls. This commit fixes the issue by letting the macro take an argument directly, and removing the jump on save_calls. I've also taken the opportunity to move all dispatch-related macros to macros.tab as it's a pinch cleaner to gather everything there.

* compiler: Honor stack frames when calling exit BIFsJohn Högberg2019-09-098-223/+311
| | | | | | | | | | | | Since exit BIFs were known not to return nor touch the stack, we allowed them to be called regardless of how the stack looked. This was a pretty small improvement which turned out to be a annoying hindrance to the new BIF tracing, as we'd overwrite the return address if we turned the specialized BIF call to an ordinary call. This commit removes that optimization. Modules compiled before OTP 23 will still work, but exit BIFs that are traced will produce incorrect stack traces.

Furthermore, if disk_log terminates BEFORE the shell starts, then the whole shell will fail to start, which will trigger another shell recursively, until the system finally shuts down. This can be reproduced with this command: $ erl -kernel shell_history true -s init restart
