Hello.
I tried to add support for the Allegrex architecture (based on mips r4000).
After building the compiler, I started testing it and found that I can't access
a variable of type float. All times i got something like
23:57:284 user_main E[JIT]: x86\compbranch.cpp:606 Jump to invalid address:
02428dd0 PC 0890a364 LR 0890a374

I have only recently started to dive into such a low level of programming, so I
do not understand everything and what i do it's only for cognition as well.
I create a simple exaple with declare float type variable and print value.
I checked other types like this and all works fine except float type.
