            Bug ID: 65837
           Summary: [arm-linux-gnueabihf] lto1 target specific builtin not
                    available
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

Hi,
I got the following error while building chromium on arm-linux-gnueabihf with
LTO enabled
when linking libshared_memory_support.so:
lto1: fatal error: target specific builtin not available
Full command line used for linking: http://pastebin.com/2ANsEyMn

This appears to be same as PR45790
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=45790), which was opened for
rs6000 for gcc-4.6.
Since it is fixed for rs6000, I am not sure if I should have re-opened it.

gcc -v:
Using built-in specs.
