Chess issue with absolute path link_with | _include _file

[Abhishek-Varma]

Error :-

WorkersError in "/home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/aie.mlir.prj/core_0_2.bcf" 
line 41, column 15: syntax error

Steps to reproduce (assuming you are inside mlir-aie's cloned repo) :-

1. Modify this line with @core(compute_tile2, "/home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/mm.o")
2. cd reference_designs/ipu-xrt/matrix_multiplication/
3. mkdir -p build
4. python3 aie2.py > build/aie.mlir
5. cd build && xchesscc_wrapper aie2 -I /proj/xbuilds/SWIP/2023.2_1013_2256/installs/lin64/Vitis/2023.2/aietools/include -DBIT_WIDTH=8 -c ../mm.cc -o mm.o
6. aiecc.py -v --aie-generate-cdo --no-compile-host --xclbin-name=final.xclbin \ --aie-generate-ipu --ipu-insts-name=insts.txt aie.mlir

The above set of steps would give you the error being reported.

Now, to further narrow it down, run the following :-

xchesscc_wrapper aie2 +w /home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/aie.mlir.prj/work \
   -d -f /home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/aie.mlir.prj/input.o mm.o \
   +l /home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/aie.mlir.prj/core_0_2.bcf -o ./core_0_2.elf

You'd see the same error. The fix, while being addressed, can be tested with the above single command itself and then later on be tested on the above 1-6 steps to confirm XCLBin's generation.

If you go ahead and simply change the content of /home/user/mlir-aie/reference_designs/ipu-xrt/matrix_multiplication/build/aie.mlir.prj/core_0_2.bcf by removing the absolute path of mm.o and just keeping "mm.o" - it'd run!

Summary with core*.bcf's content :-

1. WORKS -

_include _file mm.o

2. DOESN'T WORK -

_include _file /some/absolute/path/to/mm.o
