[llvm-commits] llvm-gcc: return the correct type for ARRAY_RANGE_REF

[Duncan Sands]

An ARRAY_RANGE_REF is for extracting a range of elements from
an array, for example elements 1 to 2 of an [3 x i32], while
ARRAY_REF is for extracting a single element, say element 2.
EmitLV_ARRAY_REF, which handles both expression types, should
return a [2 x i32]* in the first case and an i32* in the second
case (currently it always returns a pointer to the element type).
The testcase is, as ever, in Ada (Ada is the only front-end that
generates ARRAY_RANGE_REF).
