Works with -O1 instead of -O2.
gcc-4.5.2 fails in the same way. gcc-4.6.1 works.

Might be this gcc bug:

[Comment 2 Ryan Hill (RETIRED) 2011-08-08 18:49:16 UTC]

Can you add -save-temps to the commandline and attach the preprocessed source?

Confirmed with mips64el-unknown-linux-gnu-4.5.2 and 4.5.3 from crossdev on an amd64 system.

Notes:
 - only happens with -O2 -mabi=64 (any other -O level, including -O3, or -mabi=... won't trigger it)
 - does not happen with mips64-unknown-linux-gnu (tried 4.5.2, 4.5.3, and 4.6.1)
 - does not happen with 4.6.1

I'll update the suspected upstream bug report with this information.

[Comment 5 Martin Cmelik 2011-10-21 14:44:27 UTC]

Hi,

we discuss this problem on forums and it seems that problem is with -march.
GCC will be compiled with -march=native but it fails with others as "unknown march type"

Please read more information here: http://forums.gentoo.org/viewtopic-t-898044-start-25-postdays-0-postorder-asc-highlight-.html

Thank you

Do not CC arches on your own.

And don't remove mips@ from CC. :|

[Comment 8 Matt Turner 2012-05-25 02:34:39 UTC]

Upstream doesn't give a shit, apparently, and gcc-4.6 is now unmasked.
