.S file is not generated for riscv_arithmetic_basic_test

Nobody has claimed this yet.

Hello,

When I am trying to run UVM tests, using the below command to generate riscv_arithmetic_basic_test for example:

make instr_gen_run SIMULATOR=questa TEST=riscv_arithmetic_basic_test ISS=spike ISA=rv32imc SEED=1 ISA=rv32imc

Error:

And when I tried to generate the assembly file for the same test in google-riscv, it is generated properly.

Start with the make instr_gen_run path for riscv_arithmetic_basic_test and compare it with vendor/google_riscv-dv/run.py, which generates the assembly successfully. Trace why test_0.S is listed for copying but test.S is absent from out/run/tests/riscv_arithmetic_basic_test.1; done means the generated test.S is present and compiles into test.bin.
