* | Let --enable-lock-counter build an additional emulatorBjörn Gustavsson2017-05-161-2/+2
|/ | | | | | | | | | | | | "./configure --enable-lock-counter" would modify the behavior of the default emulator (usually SMP). To make lock counting more accessible, change --enable-lock-counter to build an additional emulator in the same way as: (cd erts/emulator && make lcnt) (The next commit will make it easier to start the built lock-counter emulator.)

| | | | | | | | | | | | Minimum known timeout position is saved in bot far and near wheel. This information is used to avoid scanning from current position in the cases were we know the minimum timeout position.

| |/ | | | | | | | | | | | | | | | | It turned out that the dependencies between Dialyzer and TypEr makes it impractical to have TypEr in a separate repository. Add it back to the OTP repository, but put the Erlang module 'typer' in the dialyzer application.

* Implement magic referencesRickard Green2017-02-061-24/+29
| | | | | | | | | | | | | | | | | | | | 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: Refactor out func_info into structLukas Larsson2016-10-121-2/+6
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * run_erl: Fix failing run_erl invokation on OpenBSDSverker Eriksson2016-07-051-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Symptom: run_erl does exit(0) and child program (erl) does not seem to start. Running run_erl again however brings the previous child program to life. Problem: A race causing run_erl to read 0 from master pty and exit because the child has not yet opened its corresponding slave pty. Solution: Use the non standard openpty() function instead that does not expose this race as the slave fd is opened in the parent. Question: Is there a race free way to do this with posix_openpt on OpenBSD?

* | run_erl: Don't define _XOPEN_SOURCE on OS XBjörn Gustavsson2016-03-151-3/+8
|/ | | | | | | | | | On MacOS X, defining _XOPEN_SOURCE usually *removes* features from header files. Therefore, we should not set _XOPEN_SOURCE to 600 since that will remove the prototype for vsyslog(). Setting it to an empty value or not including it will ensure that the vsyslog() prototype is included.
