Hi,
I'm fixing some compiler errors when configuring with
--enable-build-with-cxx, and ran into a curious line of code that may
indicate a bug:
static unsigned int
rest_of_handle_combine (void)
{
int rebuild_jump_labels_after_combine;
df_set_flags (DF_LR_RUN_DCE + DF_DEFER_INSN_RESCAN);
// ...
}
The DF_* values are from the df_changeable_flags enum, whose values are
typically used in logical and/or operations for masking purposes. As
such, I'm guessing the author may have meant to do:
df_set_flags (DF_LR_RUN_DCE & DF_DEFER_INSN_RESCAN);
