Description

Steps to repro:

bsc -verilog -o Top.v Top.bs

Expected result: output goes into Top.v

Expected result, slightly darker timeline: -o flag is rejected as incompatible with Verilog output, compile fails.

Actual result: -o flag silently ignored, output goes into mkTop.v (as that is the name of the module in Top.bs).

Contributor guide

Research direction
Investigate the code path for o flag handling when verilog is set. Likely the o option is being ignored in the Verilog output path. Check the argument parsing code and the function that determines the output filename.
