Initialization of buffers in neighboring tiles causes link error when compiling with CHESS

[jackl-xilinx]

In a scenario when a tile uses the local memories of adjacent tiles and those buffers are initialized with a starting value, the tool gives a linking error. The scenario looks like like:

main_tile = tile(1,3)
west_tile = tile(0,3)
north_tile = tile(1,4) 
south_tile = tile(1,2)

lut0_buf = buffer(west_tile, lut0_ty, initial_value=np.array(lut0_arr, dtype=np.int16)
lut1_buf = buffer(north_tile, lut1_ty, initial_value=np.array(lut1_arr, dtype=np.int16)
lut2_buf = buffer(south_tile, lut2_ty, initial_value=np.array(lut2_arr, dtype=np.int16)
lut3_buf = buffer(main_tile, lut3_ty, initial_value=np.array(lut3_arr, dtype=np.int16)

@core(main_tile, archvie)
def core_body():
    for _ in range_(sys.maxsize):
        di = self.din.acquire(ObjectFifoPort.Consume, 1)
        func(di, lut0_buf, lut1_buf, lut2_buf, lut3_buf)
        self.din.relase(ObjectFifoPort.Consume, 1)

This creates a llvm IR output (.ll) where the buffers are:

@lut3_buf = global [20064 x i16] [i16 0, i16 0 ...]
...

In chess, it seems to try to map these all to the same tile's local memory and complains that there is not enough space:

cd build && aiecc.py -v --aie-generate-xclbin --no-compile-host --xclbin-name=final.xclbin --alloc-scheme=basic-sequential \
            --aie-generate-npu-insts --npu-insts-name=insts.bin ../build/aie.mlir
Error: could not find space for DefSymbol 'lut1_buf' using base address 0

xchesscc Failed

However, in peano, this error does not occur. It's unclear what about the chess-clang compiler does not like the the llvm IR syntax.

Is this AIE2 or AIE2P? I suspect if anything that there is a discrepancy in the linker scripts.
