Previously, when preparing a Parameter stub during inlining, compiler
unconditionally used argument type (from the caller). This type
could be less accurate than static or inferred parameter type of
the callee. For example, the argument could originate from inlined generic ListIterator.current:
v24 <- LoadField(v23 . _current@9040228) T{X0??}
and static type could be 'int'.
This change combines argument type from callee with a parameter type
from caller during inlining. In order to get parameter type for
optional parameters, ParameterInstr is extended to hold real parameter
index and ParameterIndex::ComputeType is extended to work on
parameters which are not passed directly.
Also, this change fixes the incorrect non-nullable receiver type for
Object and Null methods.

Dart
A client-optimized language for fast apps on any platform
Dart is:
-
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
-
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
-
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
-
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
-
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
