From: Gabe Black Date: Thu, 7 Jun 2018 06:06:10 +0000 (-0700) Subject: systemc, scons: Add a mechanism to hook in the systemc tests. X-Git-Tag: v19.0.0.0~1953 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=abeafffd03229ee752b6d772f359308a88e0af04;p=gem5.git systemc, scons: Add a mechanism to hook in the systemc tests. This mechanism scans the systemc test directories as described in their original distribution. It tells scons how to build each test executable, and also how to build a json manifest file which lists all the tests and some properties about them.
