15:53 <wpwrak> whee ! connected again ! this time, internet access of the whole building was down (some fault that needed an electrician and the catv companies to work together)

16:02 <larsc> welcome to the club, my internet was down for 4 days

17:03 <whitequark> hehe http://gcc.gnu.org/gcc-4.8/changes.html

17:03 <whitequark> gcc now shows errors in clang style

17:08 Calyp has joined #qi-hardware

17:09 <larsc> I think it already did this in the previous release

17:09 <larsc> but, yea, it's good to see that competition causes improvements on both sides

17:11 jekhor has joined #qi-hardware

17:21 <pcercuei> did what?

17:23 <larsc> showing errors in clang style

17:24 <larsc> E.g. Error: Missing semicolon

17:25 <larsc> foo(1, 2)

17:25 <larsc> ^

17:39 <pcercuei> larsc: btw, mtune=mips32r2 doesn't seem optimal for the JZ

17:40 <pcercuei> sometimes mtune=r4600 gives better performance

17:40 <larsc> well the xburst has it's own pipeline anyway

17:41 <larsc> so the instruction scheduling is probably never optimal

17:41 <pcercuei> but that could be enhanced, no?

17:41 <larsc> yes, if you teach gcc about the xburst pipeline

21:22 <viric> ok I thought you were there already

21:27 <whitequark> SPEC2006?

21:27 <whitequark> larsc: if only the improvements weren't about the look and feel.
