Subject: scons: always generate sim/tags.cc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bead7f249a71f8b15ae92b0df9822abb52ca7323;p=gem5.git

scons: always generate sim/tags.cc

Due to insufficient build deps, the checkpoint tags might not get
updated; this commit solves this. Due to the uncommon nature of the
build target, regenerating tags.cc is a fairly clean solution. Since
SCons hashes file contents, it won't recompile anything unless a new
checkpoint upgrader is actually added.
