LuaJIT tries to convert to floating point

Hi All I am trying to make this small loop work on ARM64. ./luajit -jon -e 'x=0; for i=1,400000 do x=x+i end;'

The code flow reaches the point

Unimplemented: asm_conv

When I looked into it, it seems that luajit is trying to convert from INT to FLOAT.

Any ideas why it might be doing that ? Or is it a bug somewhere I need to look ?

Thanks Abhishek Dikshit
