Yes, both of these command lines work:


; "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.44.35207\bin\Hostx64\x86\ml.exe" -nologo -c -Fo test_x86_assembler.obj -Ta test_x86_assembler.S
; "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.44.35207\bin\Hostx64\x86\ml.exe" -nologo -c -Fo test_x86_assembler.obj test_x86_assembler.S
