Subject: Util: Do not style check symlinks
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a98b0cd5985fabf7b4138f0ef1e19023d3e028c;p=gem5.git

Util: Do not style check symlinks

The style checker used to traverse symlinks if they pointed to files, which can
result in style checker failure if the pointed-to file doesn't exist. This
style check is actually unnecessary, since symlinks either point to other files
that are already style checked, or files outside gem5, which shouldn't be
checked. Skip symlinks.
