cl.arkcompiler.1 Change in ArkCompiler Internal Implementation
Changed the internal implementation of ArkCompiler.
Change Since
OpenHarmony_4.1.6.1
Reason for Change
To implement the ECMAScript 2022 class and sendable class features, new bytecodes are required.
Change Description
The following bytecodes are added to the class feature:
1. definefieldbyname
2. callruntime.definefieldbyvalue
3. callruntime.definefieldbyindex
4. callruntime.defineprivateproperty
5. callruntime.callinit
6. callruntime.createprivateproperty
7. callruntime.topropertykey
8. ldprivateproperty
9. stprivateproperty
10. testin
The following bytecodes are added to the sendable class:
1. callruntime.definesendableclass
2. callruntime.ldsendableclass
Change Impact
The new bytecodes added in SDK OpenHarmony_4.1.6.1 require support from ROM in the same version. Therefore, earlier ROM in API version 11 cannot run the HAPs built by SDK OpenHarmony_4.1.6.1.
If you are using SDK OpenHarmony_4.1.6.1 and ROM in API version 10, you can set the compatiableSdkVersion: 10 option from DevEco Studio to build a HAP that can run on the ROM.
Symptom
If the SDK and ROM do not match, the following errors may occur:
jsCrash:
Load file with filename '/data/storage/el1/bundle/entry/ets/module.abc' failed, recordName 'com.example.myapplication/entry/ets/entryability/EntryAbility' not existsalong with hilog:Unable to open file 'filename' with abc file version 11.0.2.0. Maximum supported abc file version on the current system image is 9.0.0.0. Please upgrade the runtime to supported version or generate byte code with former SDK toolscppCrash:
Unable to open file 'filename' with abc file version 11.0.2.0. Maximum supported abc file version on the current system image is 11.0.1.0. Please upgrade the system image or use former version of SDK tools to generate abc files
Solution
Update the ROM to OpenHarmony_4.1.6.1 or later.
