[LLVMdev] clang promoting local to global
I have a const array allocated inside a function and the IR is showing this
has a global function (ie. there is no allocation for the space inside the
function).
For example:
const int32 local_array[256] = {constValue, constValue, ..... }
Is there any particular reason this may be occuring?
Thanks.
