Rationale: The "unoptimized code" representation is really a stack machine that pushes and pops arguments. The intermediate representation did not show the correct labeling for "temporaries", in particular around push arguments. This CL fixes that bug, making the human readable form of the intermediate much easier to understand. Also, it allows for proper stack depth computations. First use: Sharpen condition on OSR points a bit. Simple control flow collections will now allow OSR. https://github.com/dart-lang/sdk/issues/36421 https://github.com/dart-lang/sdk/issues/36409 Change-Id: I8be707af08462a22687b355b747ba85e42431ad5 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/98500 Commit-Queue: Aart Bik <ajcbik@google.com> Reviewed-by: Vyacheslav Egorov <vegorov@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Alexander Markov <alexmarkov@google.com>
Dart VM Compilation Pipeline
This folder contains Dart VM compilation pipeline.
Compilation pipeline is mainly responsible for converting AST or Kernel AST into IL flow graphs and then generating native code from IL.
It has the following structure:
| Directory | What goes there |
|---|---|
assembler/ |
Assemblers and disassemblers |
backend/ |
IL based compilation backend: optimization passes and architecture specific code generation rules |
frontend/ |
Frontends responsible for converting AST into IL |
jit/ |
JIT specific passes and compilation pipeline entry points |
aot/ |
AOT specific passes and compilation pipeline entry points |
. |
Shared code or code without clear designation. |
Currently there are no layering restrictions and components from different subfolders can reference each other.
