Gerald, this is a patch against htdocs/gcc-6/changes.html and I thought I had seen the 'changes' link in gcc.gnu.org earlier but I don't see it now (there's only a release criteria link). Is this a bug? Ok to apply?

New Targets and Target Specific Improvements

+

AArch64

+
    +
  • + The new command line options -march=native, + -mcpu=native and -mtune=native are now + available on native AArch64 GNU/Linux systems. Specifying + these options will cause GCC to auto-detect the host CPU and + rewrite these options to the optimal setting for that system. + If GCC is unable to detect the host CPU these options have no effect. +
