Hi all,
Using gcc 4.3.3 compiling linux kernel 2.6.30-rc6 I get the followig error:

I'll note that, even though the bug is very rare and no testcase is
known in general, it affects every target with delay slots -- so

what's wrong ? no more details were put e.g. here:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37179
This was different problem, with -march=native. And according to [1],
-march=geode works
The following tests fail with error: alignment of array elements is greater
than element size:

Although this bug doesn't seem to currently trigger on i686 or x86_64 linux,
it is still failing on hppa-unknown-linux-gnu.

In the Linux kernel, we use (except in certain very restricted contexts) only
the subset of the x86 instruction set that can never cause #TS faults and thus
doesn't use the FSAVE/FXSAVE/XSAVE state. It appears that we need to add new
-mno- options (-mno-sse -mno-sse2 -mno-sse3...) as gcc starts
--- Comment #1 from pinskia at gcc dot gnu dot org 2009-05-24 18:22 ---
I don't see why adding -mno-mmx is a problem (that disables all of the MMX and
SSE instructions). -mno-mmx will always disabling all of the future subsets
too.

I guess I would request that this be added to the documentation. Keep in mind,
though, that this should include x87, MMX, SSE, and AVX.

No, MMX and SSE are handled

There is a typo hiding somewhere, we should have and:DI instead of and:SI.

Confirmed. But properly supporting this is a bit of a hassle because we need

GCC 4.4.0 (and earlier) requires a copy constructor for elements that are not
explicitly initialized using a non-empty aggregate initializer list. Thus the
following fails
struct B { B() { } private: B(B const); };
struct A { int a; B b; };
int main() {
A a = { 0 };
}
main.cpp: In function
