Could you please send a complete patch that includes both Waldemar changes and yours ? Also, please read the comments in https://patchwork.ozlabs.org/patch/800406/, they pointed out the fact that -ffp-contract only exists since gcc 4.6, so its use should be made conditional. Read the comments from Arnout, who suggests how to address that. Thanks a lot! Thomas -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
