Check the right register set when deciding if there is a leftover pop single. This worked by accident on non-Fuchsia ARM64 because there is an even number for both CPU and FPU registers, but Fuchsia has a different number of preserved CPU registers due to the shadow call stack. TEST=no Fuchsia ARM64 bots; inspect disassembly of the entry stub Bug: b/226647006 Change-Id: Ie0c7fa4a3b713d5b9fb21e9e778d620c7728bc39 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/239160 Reviewed-by: Alexander Markov <alexmarkov@google.com> Commit-Queue: 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.
