Roles of executables in out/DebugARCH directories

[Goran Ferenc]

Hello All,

I am interested in roles of executables in out/DebugARCH directories?

Among others there are dartino, dartino-vm and dart executable files. Can someone explain which role has each of them?

Best regards,
Goran

Hi Goran,

We have the following binaries for most architectures:

dartino-vm: The standalone VM which support both building programs and running programs from snapshots

dartino: Small executable for driving the compiler. The compiler is written in Dart and is run through the Dart VM

dart: The "classic" Dart VM for running the compiler. This binary is not build bu this project, but copied from third_party/bin

dartino-flashify: Tool to generate an assembler file for the Dartino program heap from a Dartino snapshot. This can be used to link a Dartino program into an executable using normal ld. This is used when running Dartino programs on embedded devices.

flashtool: Tool for generating a Dartino program heap which can be loaded by a VM running on an embedded device. Using this is somewhat complicated, and we are working on ways to improve this.

*_cc_tests: binaries for running the tests written in C++.

libdartino.a: The Dartino VM as a static library

Hope that helps.

Regards,

Søren

Hi Søren,
 
Thank you for this prompt reply.

If I am correct, the arhitecture should be like this:
dartino-vm = dartino compiler + virtual machine?

I mean, we should be able to run dart programs using only dartino-vm, without having dart and dartino executables in out/DebugARCH? If this is true, what are the commands I should use?
From the dartino wiki page, this is possible only if I use "./dartino export dart_progam.dart to dart_progam.snapshot", and then run "./dartino-vm dart_progam.snapshot". So, in order to make the snapshot I have to use dartino executable which uses dart executable as well...
 
Regards,
Goran

The dartino-vm is only the VM and runtime - not the compiler. The compiler is a Dart program running in the "classic" Dart VM, which is invoked using the dartino program. As part of the compilation the Dartino VM is used as well.

You are right that you can run dart programs using only the dartino-vm. You run the compiler 'dartino export dart_progam.dart to dart_progam.snapshot' on a host machine which supports the compiler, and then transfer the snapshot to the device where only the dartino-vm is available. The snapshot is architecture independent and does not have to be produced on a machine with the target architecture.

Søren
