jadx fails to decompile methods optimized by simplify

[axnsan12]

Using the master branch.

Ran as:

java -Xmx512M -Xms256M -jar simplify/build/libs/simplify.jar btpay-1.dex --max-address-visits 100000 --max-call-depth 150 --max-method-visits 10000000 --output btpay-dex-1-simplify-2.dex -ie | tee simplify-dex-1.log

Using jadx to decompile, I get errors such as

/*
Error: jadx.core.utils.exceptions.JadxRuntimeException: Unreachable block: B:9:0x001c

Thanks for the issue. I think you have enough here to try and reproduce. Btw, what version of jadx are you using?

My day job is keeping me pretty busy, but I occasionally reward myself with time to work on simplify issues. :D

Got the same behavior some time ago.

@axnsan12 I can decompile your simplified.dex file with my GDA. probably your tool has problems.
