On a system which supports 64-bit implementation but with TARGET_ILP32
ABI, like HPUX on ia64, the gcc-4.1 compiler generates incorrect code
for the dejagnu test gcc.dg/tree-ssa/pr23386.c. The problem seems
because that the gen_addr_rtx() in tree-ssa-address.c always returns
Pmode rtx. On a TARGE
Yes. I know it doesn't fail on IA64-HPUX. The reason is
that the dereferencing expression has been transformed as:
tmpvar = index+offset;
*tmpvar;
during induction variable optimization, Where tmpvar has SImode.
PPC has different costs to compute induction variables as on IA64-HPUX.
