[I couldn't attach the code as an attachment, bugzilla has a bug.]
The program below has to be compiled with -mavx to allow the AVX intrinsics
being used. But this also triggers using the use of the vmovss instruction

(In reply to comment #3)
Gcc 4.4 and above supports different target options on the function
level but not on a basic block level. So you can create an interneral
version for AVX.
This doesn't work either. Aside

No, it's *NOT* undefined. The libc interface decides what is defined and what
is not and it is *EXPLICITLY* documented that NULL pointers are printed as
(null).
The standard might leave it undefined but this does

This is NOT a dup of 15574.

That is true but GCC is a C compiler and not a glibc implemention C compiler.
This doesn't mean anything. As soon as you configure gcc to target it to Linux
the behavior of the runtime is as defined by the C library
--- Comment #10 from drepper at redhat dot com 2005-12-30 23:44 ---
glibc *is* the world as far as Linux is concerned. You consistently and
deliberately misinterpret what I write: I'm not talking about any platform
which does not use glibc or glibc's behavior.
And RTH already

That is not true at all and you know that. There is uclibc.
Now you've completely given up on logic? First of all, uclibc and whatever
other libc immitation is out there does not define the linux API. glibc

What happens if you use -fno-common?
In this case the variable gets the index of .bss in the symbol table instead of
using SHN_COMMON.

Using gcc's section attributes won't fully work either.
Using __attribute((section(.rodata))) is OK in the compiler, although the
assembler (correctly) complaints. But what is really needed is
