* erts: Keep literal lists in the line tableJohn Högberg2021-10-221-1/+1
| | | | | | | | | This saves us from having to convert them to lists on the fly at runtime, which is extremely annoying because of the special case for "module_name.erl" This also means that file paths can be arbitrarily long in the future.
* erts: Statically allocate trap export entries againJohn Högberg2020-11-131-4/+4
| | | | | Now that we no longer execute code inside them, they no longer need to be allocated at runtime.

* jit: Make all code read-only, dual-mapping writable pagesJohn Högberg2020-11-051-1/+1
| | | | | | | | This allows the JIT to be used on systems that enforce a W^X policy. To help catch related errors at compile time, all code pointers have been marked `const`.

* erts: Refactor bif exports to be allocated at start-timeLukas Larsson2020-09-211-10/+10
| | | | | | | | This is needed as BeamAsm needs the export entries to be executable, which means that we need to allocate them. Co-authored-by: John Högberg <john@erlang.org> Co-authored-by: Dan Gudmundsson <dgud@erlang.org>

* | erts: Add deallocation veto for magic destructorsSverker Eriksson2017-02-141-2/+4
|/ | | | | A magic destructor can return 0 and thereby take control and prolong the lifetime of a magic binary.

* Implement magic referencesRickard Green2017-02-061-7/+2
| | | | | | | | | | | | | | | | | | | | Magic references are *intentionally* indistinguishable from ordinary references for the Erlang software. Magic references do not change the language, and are intended as a pure runtime internal optimization. An ordinary reference is typically used as a key in some table. A magic reference has a direct pointer to a reference counted magic binary. This makes it possible to implement various things without having to do lookups in a table, but instead access the data directly. Besides very fast lookups this can also improve scalability by removing a potentially contended table. A couple of examples of planned future usage of magic references are ETS table identifiers, and BIF timer identifiers. Besides future optimizations using magic references it should also be possible to replace the exposed magic binary cludge with magic references. That is, magic binaries that are exposed as empty binaries to the Erlang software.

* | erts: Change erl_exit into erts_exitSverker Eriksson2016-02-241-1/+1
|/ | | | | | | | | | | | | | | | | This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).

* erts: Use fast path for list_to_binary([Bin]) caseBjörn-Egil Dahlberg2013-04-301-0/+11

* Replace io_list_len() with erts_iolist_size()Björn Gustavsson2011-05-101-5/+8
| | | | | | | | | | | | | | | | | | The io_list_len() function returns an int, where a negative return value indicates a type error. One problem is that an int only consists of 32 bits in a 64-bit emulator. Changing the return type to Sint will solve that problem, but in the 32-bit emulator, a large iolist and a iolist with a type error will both return a negative number. (Noticed by Jon Meredith.) Another problem is that for iolists whose total size exceed the word size, the result would be truncated, leading to a subsequent buffer overflow and emulator crash. Therefore, introduce the new erts_iolist_size() function which returns a status indication and writes the result size through a passed pointer. If the result size does not fit in a word, return an overflow indication.

* Fix 18 exabyte memory allocation failureBjörn Gustavsson2011-03-091-1/+1
| | | | | | | | | | | | The new_binary() function takes a size argument that is an int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8), any sizes >= 0x8000000 become 0xffffffff80000000 and above and triggers a memory allocation failure. Change the type of the size argument to Uint, and change any callers that cast the argument to an int. Correction-by: Jon Meredith
