You can specify command‑line options by setting the value of the RVCT31_ASMOPT environment variable. The syntax is identical to the command line syntax. The assembler reads the value of RVCT31_ASMOPT and inserts it at the front of the command string. This means that options specified in RVCT31_ASMOPT can be overridden by arguments on the command‑line.
