| <p>This is a generic method for doing formatted output. It takes an |
| additional argument <code>dump_kind</code> which signifies the type of |
| dump. This method outputs information only when the dumps are enabled |
| for this particular <code>dump_kind</code>. Note that the caller doesn’t |
| need to know if the particular dump is enabled or not, or even the |
| file name. The caller only needs to decide which dump output |
| information is relevant, and under what conditions. This determines |
| the associated flags. |
| </p> |
| <p>Consider the following example from <samp>loop-unroll.c</samp> where an |
| informative message about a loop (along with its location) is printed |
| when any of the following flags is enabled |
| </p><ul class="no-bullet"> |
| <li>- optimization messages |
| </li><li>- RTL dumps |
| </li><li>- detailed dumps |
| |
| </li></ul> |

| <div class="example"> |
| <pre class="example">int report_flags = MSG_OPTIMIZED_LOCATIONS | TDF_RTL | TDF_DETAILS; |
| dump_printf_loc (report_flags, locus, |
| "loop turned into non-loop; it never loops.\n"); |
| </pre></div> |

| </dd> |
| <dt><code>dump_basic_block</code> |
| <a name="index-dump_005fbasic_005fblock"></a> |
| </dt> |
| <dd><p>Output basic block. |
| </p></dd> |
| <dt><code>dump_generic_expr</code> |
| <a name="index-dump_005fgeneric_005fexpr"></a> |
| </dt> |
| <dd><p>Output generic expression. |
| </p></dd> |
| <dt><code>dump_gimple_stmt</code> |
| <a name="index-dump_005fgimple_005fstmt"></a> |
| </dt> |
| <dd><p>Output gimple statement. |
| </p> |
| <p>Note that the above methods also have variants prefixed with |
| <code>_loc</code>, such as <code>dump_printf_loc</code>, which are similar except |
| they also output the source location information. |
