Rationale: A basic peephole optimizer with window size one that avoids redundant push-pop sequences already results is substantial savings in code size and runtime, without any noticeable impact on compile time (the peephole is very, very fast). Performance: Golem unoptimized code (which typically runs -90% compared to optimized code, sees 5-60% improvements https://github.com/dart-lang/sdk/issues/36409 Change-Id: I08db4b3dbc92377d89340a4969db6e664e54bceb Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/102980 Commit-Queue: Aart Bik <ajcbik@google.com> Reviewed-by: Vyacheslav Egorov <vegorov@google.com> Reviewed-by: Ryan Macnak <rmacnak@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.
