From: Holger Hans Peter Freyther Date: Fri, 20 Jul 2012 13:03:56 +0000 (+0800) Subject: mips: Autodetect MIPS DSP rev1 and rev2 instructionset X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=08e92ba1e009d8b55e4ea44b4169ae80252b24f1;p=profile%2Fivi%2Fqtbase.git mips: Autodetect MIPS DSP rev1 and rev2 instructionset Not every MIPS SoC has the DSP extensions, auto-detect them by using builtin GCC functions. Check for the DSP macros and add the result for rev1 and rev2 to the cpufeatures.
