• Subject: [PATCH] fix bootstrap (tre-ssa-pre.c)

Hi,

since the CALL_EXPR conversion patches went in, bootstrap is broken for me. The patch below fixes it. Regtest however has not yet completed. I however don't understand how the assert that was added was never triggered before, so I assume any regression that this patch would trigger can only been there before already. Right?

    * tree-ssa-pre.c (create_value_expr_from): Update gcc_assert()
    after CALL_EXPR conversion to avoid uninitialized value
    warning.
