#1
if I delete the below "memcpySequence" in Compiler.xml
Will solve
Code:
Catched exception 'java.lang.NullPointerException' while compiling 0x08B15504 (0x08B151F0-0x08B15798)
Attach log and profiler for each case

Code:
<NativeCodeSequence name="memcpySequence">
        <Class>jpcsp.Allegrex.compiler.nativeCode.MemcpySequence</Class>
        <Parameters>$a3,$a2,$t0,1,1</Parameters>
        <BranchInstruction>@08B31770</BranchInstruction>

Interesting! Could you provide a compiler DEBUG log of the good case (i.e. with the memcpySequence entry deleted).

Thank you!
Always include a complete log file at INFO level in your reports. Thanks! How to post a log

Thank you!

I've tried to solve this case in a generic way with r3503. Could you generate a new compiler DEBUG log to check if the fix worked properly?

Thank you! I just wanted to check if the DEBUG log I added was displayed:
Code:
05:11:30 DEBUG compiler - ExtractorThread - 0x08B1541C: branching to the 2nd instruction of a native code sequence, assuming the 1st instruction
Always include a complete log file at INFO level in your reports. Thanks! How to post a log
