Hmmm... it seems not. -ffat-lto-objects exists in 4.7 but not in 4.6. -flto was added in 4.6.On Tue, Nov 26, 2013 at 6:55 AM, Kyrill Tkachov <kyrylo.tkachov@arm.com> wrote:On 26/11/13 14:36, H.J.

Could someone please comment on whether this is the correct approach? CC'ing H.J. since he wrote the lto.exp file.Does -ffat-lto-objects always work when -flto is supported? If yes, OK for trunk.The gcc manual says about -ffat-lto-objects: " This option is effective only when compiling with -flto and is ignored at link time". I'd think that it's supposed to always work with -flto.Was -ffat-lto-objects added together with -flto?
