X-Git-Tag: firefly_0821_release~27981^2~48 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6240d92f2f2fb74094b66b3510733fa0a1e2631a;p=firefly-linux-kernel-4.4.55.git sh: Wrap CPU tuning through cc-option. Some compilers don't support the explicit CPU tuning, while binutils is still able to handle the special subtype-specific opcodes. Make the CFLAG optional, falling back on the compiler default if nothing better exists.
