error: expected: insn.id() == ARM64_INS_BL

[spr234]

I am getting following error

Dart version: 3.1.0, Snapshot: 7dbbeeb8ef7b91338640dca3927636de, Target: android arm64 libapp is loaded at 0x1cb1b260000 Dart heap at 0x1cc00000000 Analyzing the application at ....\src\CodeAnalyzer_arm64.cpp: 984: error: expected: insn.id() == ARM64_INS_BL

I am using Windows

also tried on debian trixie, same error

How can I fix that?

[worawit]

I guess it is an unexpected generated code pattern from Dart compiler.

I pushed a patch to not stop the program if an error occurs in analysis step. You can rerun with "--rebuild" option. An error is still printed. Also, please give me an error message with printed assembly. I might be able to fix a bug.

Committed a fix.

I have no full assembly to check. So, it might be wrong. If there is still an error, can you send me a library?

[spr234]

I am still getting

Where can I send you library?

By the way, apart from that error message, Blutter is working like a charm !!

[worawit]

I guess you don't have to send me a library anymore. Just fixed the last error. Thanks for a bug report.

[spr234]

Yup, No more error Thankyou for making such tool.

I have same error in dart 3.1.3
