Can you please post complete command line that triggers the bug, as outlined in
[1]? Something like:

g++ <... options ...> -fpreprocessed TEncSbac.ii

Please also use -march=<some arch> instead of -march=native. You can see which
architecture -march=native is compiling for by adding -### to the command line.

Also, your command line lists -m32, but the preprocessed file is clearly 64-bit
(-m64) produced.  And, if it is only reproduceable with -flto, we need all *.ii
files through which it can be reproduced (perhaps link with -r -nostdlib -flto
and try to remove unneeded objects).

Without lto it compiles fine.
It is Gentoo x86/x86_64 enabled package.
I am going to attach all the ii files, thank you.

This is the command line that is enough to get the crash:

/usr/bin/x86_64-pc-linux-gnu-g++  -m32 -fPIC -flto=4 -fuse-linker-plugin -O2
-ggdb -pipe -march=core2 -mtune=core2 -mno-3dnow -mno-sse4.2 -mno-avx

-mno-sse4.2 -mno-avx -o libx265.so.0.8 
encoder/CMakeFiles/encoder.dir/__/Lib/TLibEncoder/TEncSbac.cpp.o  -r -nostdlib

When I ran it with

/usr/bin/x86_64-pc-linux-gnu-g++  -m32 -fPIC -flto=4 -fuse-linker-plugin -O2
-ggdb -pipe -march=core2 -mtune=core2 -mno-3dnow -mno-sse4.2 -mno-avx

-mno-sse4.2 -mno-avx -o libx265.so.0.8 -fpreprocessed ./TEncSbac.ii  -r
-nostdlib

(or without -fpreprocessed) it does link the library!

I attached gzipped object file got using -march/tune=core2.

Untested fix.  Unfortunately, as the testcase is only ELF object with LTO
bytecode in it, I don't have a testcase for the testsuite nor anything that
could be reduced.

--- Comment #2 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
I think following what i386 does is reasonable for now.

I'm a bit dubious of the whole Save design - logically it would be cleaner
if the gcc_options structures were saved just before finish_options, and
then use of option-changing attributes were to process options with a copy
of that structure (if this hadn't already been done for that particular
attribute value), with finish_options and subsequent processing then being
done for the new copy.  But that would be quite a lot of work, to complete
a clean separation of option processing working on such structures from
options processing that actually needs global effects, and then you'd need
to work out how to represent things for LTO.

Maybe, but have not included that in my current bootstrap.
If we change that, we should also change it in the TARGET_64BIT case a few
lines above it.

Definitely unrelated, please file a different bug, and if at all possible try
to reduce it.

I get these kind of linker errors a lot with "-flto -march=amdfam10" on
my test machine. The problem is that the configure checks for the
extended instructions somehow succeed with -flto even though -march
disables them. It would be good if autotools would pass -fno-lto during
configuration automatically. This would also fix cases where configure
scans the assembler output and fails in case of slim-objects.
