The submitter sent me his preprocessed source file, from which I
extracted this small test case:
typedef struct { float u; float v; } P2;
static void PointInTri (P2 pl, P2 pn, P2 v0, P2 v1, P2 v2)
{
P2 e0 = v2;
}
This causes the same ICE in simplify_gen_subreg when compiled on
ia64-linux with gcc version 3.3 20021106 (experimental) and with
3.2.1 20021105 (prerelease). GCC 2.96RH ICEs in emit_move_insn.
