------- Comment #16 from rguenth at gcc dot gnu dot org 2007-09-18 13:16 -------
I can still see the ICE with -O2 -ftree-loop-linear and the testcase from
comment
2 on trunk (x86_64):
t.i: In function 'lsp_weight_quant':
t.i:3: internal compiler error: in lambda_loopnest_to_gcc_loopnest, at
lambda-code.c:1839
gcc_assert (TREE_CODE (stmt) != PHI_NODE);
but
(gdb) call debug_generic_expr (stmt)
best_id_6 = PHI <best_id_49(6), i_46(5)>
