[PULL 08/63] hw: Include minimal source set in user emulation build

Posted by Paolo Bonzini 1 year, 9 months ago

From: Philippe Mathieu-Daudé <philmd@linaro.org>

Only the files in hwcore_ss[] are required to link a user emulation
binary.

Have meson process the hw/ sub-directories if system emulation is
selected, otherwise directly process hw/core/ to get hwcore_ss[], which
is the only set required by user emulation.

This removes about 10% from the time needed to run
"../configure --disable-system --disable-tools --disable-guest-agent".
