asm_test folder being empty after "successful" run

[LF-RoGu]

Bug: No .S files generated during --steps gen using Xcelium and custom target.

Even though run.py reports that test generation ran successfully, the expected .S files in asm_test/ are never generated. This happens with a custom target using rv32imac ISA and Xcelium as the simulator.

OS: RHEL 9
Simulator: Xcelium (Cadence) — --simulator xlm
Command used:
python3 run.py --custom_target /path/to/target/rv32imac
--isa rv32imac --mabi ilp32
--test riscv_arithmetic_basic_test
--simulator xlm
--steps gen --verbose
-o out_test_debug

Output:
out_clean_test/asm_test/ → empty
out_clean_test/compile.log → warnings only
No errors shown in stdout

Attempted Fixes:
Verified correct testlist.yaml and target.yaml
Verified correct ISA/ABI
Tried with --target rv32i → also failed

Any help to solve this would be greatly appreciated, as currently I'm trying to validate that the tool was successfully installed and that I'm using it correctly. (Which aparently is not the case yet)
