I guess, y2 does not need tcg temporary variables either, since it is
only for ld/st operation (all memory operations must be only processed
by y2 or x1).
At present, I can generate the tcg code for _start TB block, and can
execute to 2nd TB block __libc_start_main (although I don't know whether
Oh, we can not only assume y1 and x1 is the last execution in a bundle,
e.g. in __libc_start_main:
11330: c6f106c685928d8a{ addi r10, sp, 40 ; addi r13, sp, 32 ;
st r25, r30 }
11338: 286201401fca{ moveli r10, 0 ; st r10, r0 }
In this case, r10 will be over

At present finish decoding the first TB block: _start. Always let y1 and
x1 pipe at the last which may content jump instructions.
The related disassembly code is below which is the same as the objdump:
y0: 500bfdb4 move r52, r54
y2: 02080760 ld r1, r54
y1: 1c064000
