# The script has two modes of execution:
|
|
#
|
|
# 1) if invoked with a path on the command line (possibly
|
|
# preceded by a "--" argument), it will run the analysis on
|
|
# an existing build directory
|
|
#
|
|
# 2) otherwise, it will configure and builds QEMU itself in a
|
|
# "+build" subdirectory which is left around when the script
|
|
# exits. In this case the command line is passed directly to
|
|
# "make" (typically used for a "-j" argument suitable for your
|
|
# system).
