The main difference between the C++ front-end and the C front-end in this
respect is how they
repesent bit-fields.
for the C++ front-end we get the following output from SRA:
Cannot scalarize variable D.1693 because its type cannot be decomposed
but for the C front-end we get:
Scan results:
D.1237: n_uses=0 n_copies=2
Initial instantiation for D.1237
Using element-copy for D.1237
D.1237.i1 -> SR.12
D.1237.i2 -> SR.13
D.1237.i3 -> SR.14
So to me this looks like a SRA bug in that it should be using BIT_FIELD_REF
instead if it can.
