TryCatchOptimizer pass reasonably expects for all MayThrow instructions to have environment. AllocateSmallRecord instruction which is inserted when boxing an unboxed record result of a call didn't have environment, which caused crash in TryCatchOptimizer. The fix is to copy the environment from a call instruction when inserting AllocateSmallRecord.

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.
