Various passes +register dumping pass-specific information via <code>dump_register</code> in +<samp>passes.cc</samp>. During the registration, an optimization pass can +select its optimization group (see <a href="Optimization-groups.html#Optimization-groups">Optimization groups</a>). After +that optimization information corresponding to the entire group +(presumably from multiple passes) can be output via command-line +switches. Note that if a pass does not fit into any of the pre-defined +groups, it can select <code>OPTGROUP_NONE</code>. +</p> +<p>Note that in general, a pass need not know its dump output file name, +whether certain flags are enabled, etc. However, for legacy reasons, +passes could also call <code>dump_begin</code> which returns a stream in +case the particular pass has optimization dumps enabled. A pass could +call <code>dump_end</code> when the dump has ended. These methods should go +away once all the passes are converted to use the new dump +infrastructure. +</p> +<p>The recommended way to setup the dump output is via <code>dump_start</code> +and <code>dump_end</code>. +</p> + + + +</body> +</html> |
