Hi,
2 questions:
1) Is "gcc -r" officially supported by gcc?
It apparently works, but I can't find it documented anywhere in GCC's
documentation.
2) Is "gcc -r" any different from using "gcc -Wl,-r"?

Hello,
I used the spim5 gcc 4.0.2 to study gcc port. but I found there are lots of
the 'move' insns redundancy code. For example, the C code like this:
i=1;
i = i + 5;
the Spim compiler will generate the code like the following(PS:RX is the
register) .
li R0, #1
SW R0, 0(MEM)
LW R0

As I mentioned; it is emulated. So it works, by default, though it is
not native support (that is there is no ABI helper that speeds it up).
In fact tls_runtime sh
Hi,
following on from http://gcc.gnu.org/ml/gcc/2008-05/msg00202.html
should I expect
"--enable-tls"
to produce a functional result on {intel,powerpc}-*-darwin{8,9}
or should all testcases with thread local requirements be wrapped with
{ dg-require-effective-target tls_runtime }
thanks,

Please read http://gcc.gnu.org/contribute.html
In particular you need a copyright assignment, ChangeLog entry, and testing.

A patch follows. I didn't take care of the scheduling case the correct

Can someone please review (works for me (c)) and merge?
