[LLVMdev] LLVM-GCC & GV zeroinitializers, 2.5 vs 2.6.

[Julien Lerouge]

Hello folks,

I have a small piece of C code written like this:

    typedef struct {
        char a;
        int b;
        int c;
    } foo;
    
    foo myFoo[5] = {{0}};

With llvm-gcc 2.5, I get the following IR:

    %struct.foo = type { i8, i32, i32 }
    @myFoo = global [5 x %struct.foo] zeroinitializer, align 32

With the current 2.6, I get this:

    %0 = type { i8, [11 x i8] }
    %struct.foo = type { i8, i32, i32 }
    @myFoo = global [5 x %0] zeroinitializer, align 32

Is there any reason for the change ? It is weird that in the end, with
2.6 myFoo doesn't have the [5 x %struct.foo]* type.

Thanks,
Julien
