[cfe-dev] incomplete vector initialization

[Anton Yartsev]

Noticed that only the first vector element is initialized in IR when 
initializing a vector with a single literal:
vector int v = (vector int)(1);
turns into
@v = global <4 x i32> <i32 1, i32 0, i32 0, i32 0>, align 16 ; <<4 x 
i32>*> [#uses=0]

Attached is the patch and the test.
