# Priority of locks in parallel runs of the JVM IR backend
|
|
|
|
To avoid deadlocks in backend code, please make sure that a lock that comes earlier in the list
|
|
never gets acquired by a thread that already holds one of the locks that come later.
|
|
|
|
1. `JvmBackendContext.inlineMethodGenerationLock`. Used to prevent concurrent generation of inline functions.
|
|
1. Global `IrLock` instance. Used in `SymbolTable`,
|
|
`lazyVar` instances in `IrLazyDeclaration`, `Fir2IrLazyDeclaration` subclasses,
|
|
`Fir2IrDeclarationStorage`.
|
|
1. - lock in `ClassBuilderAndSourceFileList.asBytes`.
|
|
- lock on `methodNode` in `InlineCodegen.cloneMethodNode`.
|
|
- Locks protecting `InlineCache` maps. |
