From: Thomas De Schampheleire Date: Fri, 5 Mar 2021 13:48:37 +0000 (+0100) Subject: package/openblas: strip any optimization flag where needed X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0508b570530f381a42d9dd04757032ce4e72a57;p=buildroot.git package/openblas: strip any optimization flag where needed openblas strips off -O1-O3 for certain source files, but forgets to handle -Os, -Og and -O. This means that the intended effect of 'no optimization' is not always reached.
