This could be somewhat similar, I really wonder if this needs a temp:
TYPE T1
INTEGER :: a(3)
END TYPE T1
TYPE(T1), POINTER :: x,y
ALLOCATE(x,y)
x%a=y%a
END
--
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36933
another case where an unneeded temp is created. Maybe not so easy to fix?
SUBROUTINE S1(a)
integer :: a(:),i,N
N=SIZE(a)
a=(/(I,I=1,N)/)
END SUBROUTINE
--
Summary: unneeded temporary

Version: 4.4.0
Status: UNCONFIRMED
since b is an allocatable without the target attribute, there is no way it can
'alias' a. No need for a temp thus
SUBROUTINE S(a)
INTEGER, POINTER, DIMENSION(:) :: a
INTEGER, DIMENSION(:), ALLOCATABLE :: b
ALLOCATE(b(10))
b(a)=1
END SUBROUTINE S
gfortran -c -Warray-temporaries test.f90
--- Comment #1 from jv244 at cam dot ac dot uk 2008-11-14 08:50 ---
that might be an even simpler case:
SUBROUTINE S(a,i,j)
INTEGER, POINTER, DIMENSION(:) :: a
INTEGER, DIMENSION(:), ALLOCATABLE :: b
INTEGER :: i,j
ALLOCATE(b(10))
b(i:j)=a(i:j)
END SUBROUTINE S

The output of -Warray-temporaries could be enhanced:
CALL fft_1dm ( fft_type, sign, .TRUE., n(2), mx2*mz2, abuf, bbuf, 1.0_lp
)
1
Warning: Creating array temporary at (1)
I.e. the (1) should maybe point to the variable
no need for a temp here.
SUBROUTINE S(b,i,j)
INTEGER, DIMENSION(:) :: b
INTEGER :: i,j

3 possible ways to fix this:

(ptr).

You can do:
float *cf = c;
return cf[0] + cf[1];
Or after my patch just c[0] + c[1].

Since the support is there fully in 4.3.0, I am going to close this as fixed,
there might be some warnings that can't be disabled via this way but please
file a separate bug for each one.

Here is a small example:
struct a {float x, y; };
struct a f(struct a b)
{
return __real b;
}
int f1(int *b)
{
return __imag b - __real b;
}

As mentioned it is only a GCC extension that the value is a constant.

I think we can close this as won't fix. LTO has a testsuite part already so it
is not a big deal.

This needs VRP really to be run at -O0 which I don't think is going to happen
any time soon.

Actually I use sizeof all the time on pointers so I don't think this is useful.
In fact it falls down with meta programming.
That is:
#define bitcase(type, a) ({typeof (a) b = a; type c; int

-Wcast-qual exist already and works like what you want it to work.

t.c:8: warning: ISO C restricts enumerator values to range of 'int'
t.c:14: warning: left shift count = width of type
This is still correct. Even if we had sizeof(MyEnum) == 2, the types of dummy
will still be an
I would expect gcc to generate comparable code for both functions below, or
perhaps even better code for foo() than for bar() since the code in foo() is
likely to be more common than the equivalent code in bar(). However, the code
produced for foo() is suboptimal in comparison to the code for

This works for me on the trunk. I either get a cmove or a branch.
