Can't pass in parameters to online compiler

[fritzone]

While trying the example from the main page with the options that are to be passed to the compiler I get the following error:

thread 'main' panicked at 'could not find file -O3

Some system info:

$ echo $SHELL
/usr/bin/zsh

running on Linux Mint:

$uname -a
Linux flap 4.15.0-65-generic #74-Ubuntu SMP Tue Sep 17 17:06:04 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

and

$ rustc --version
rustc 1.39.0 (4560ea788 2019-11-04)

and the stacktrace:

$ RUST_BACKTRACE=full cce compile arm64g630 -- -O3

This also happens to me in Windows 10 OS.
