Subject: scons: Call summarize_warnings() when scons finishes building.
X-Git-Tag: v20.0.0.0~238
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1c59559ddb8be4fbad2c0e730df24f497c510283;p=gem5.git

scons: Call summarize_warnings() when scons finishes building.

This will ensure that warnings are not all shoved off the end of the
scrollback buffer or lost in a sea of compiler lines, and that the user
will actually have a chance to see and read them.
