Directives controlling the set of instructions accepted by the
assembler have effect for instructions between the directive and any
subsequent directive overriding it.
<a name="index-g_t_0040code_007b_002earch_007d-directive_002c-TIC6X-2212"></a>
<dl><dt><code>.arch </code><var>arch</var><dd>This has the same effect as <samp><span class="option">-march=</span><var>arch</var></samp>.
<p><a name="index-g_t_0040code_007b_002ecantunwind_007d-directive_002c-TIC6X-2213"></a><br><dt><code>.cantunwind</code><dd>Prevents unwinding through the current function. No personality routine
or exception table data is required or permitted.
<p>If this is not specified then frame unwinding information will be
constructed from CFI directives. see <a href="CFI-directives.html#CFI-directives">CFI directives</a>.
<p><a name="index-g_t_0040code_007b_002ec6xabi_005fattribute_007d-directive_002c-TIC6X-2214"></a><br><dt><code>.c6xabi_attribute </code><var>tag</var><code>, </code><var>value</var><dd>Set the C6000 EABI build attribute <var>tag</var> to <var>value</var>.
<p>The <var>tag</var> is either an attribute number or one of
<code>Tag_ISA</code>, <code>Tag_ABI_wchar_t</code>,
<code>Tag_ABI_stack_align_needed</code>,
<code>Tag_ABI_stack_align_preserved</code>, <code>Tag_ABI_DSBT</code>,
<code>Tag_ABI_PID</code>, <code>Tag_ABI_PIC</code>,
<code>TAG_ABI_array_object_alignment</code>,
<code>TAG_ABI_array_object_align_expected</code>,
<code>Tag_ABI_compatibility</code> and <code>Tag_ABI_conformance</code>. The
<var>value</var> is either a <code>number</code>, <code>"string"</code>, or
<code>number, "string"</code> depending on the tag.
<p><a name="index-g_t_0040code_007b_002eehtype_007d-directive_002c-TIC6X-2215"></a><br><dt><code>.ehtype </code><var>symbol</var><dd>Output an exception type table reference to <var>symbol</var>.
<p><a name="index-g_t_0040code_007b_002eendp_007d-directive_002c-TIC6X-2216"></a><br><dt><code>.endp</code><dd>Marks the end of and exception table or function. If preceeded by a
<code>.handlerdata</code> directive then this also switched back to the previous
text section.
<p><a name="index-g_t_0040code_007b_002ehandlerdata_007d-directive_002c-TIC6X-2217"></a><br><dt><code>.handlerdata</code><dd>Marks the end of the current function, and the start of the exception table
entry for that function. Anything between this directive and the
<code>.endp</code> directive will be added to the exception table entry.
<p>Must be preceded by a CFI block containing a <code>.cfi_lsda</code> directive.
<p><a name="index-g_t_0040code_007b_002enocmp_007d-directive_002c-TIC6X-2218"></a><br><dt><code>.nocmp</code><dd>Disallow use of C64x+ compact instructions in the current text
section.
<p><a name="index-g_t_0040code_007b_002epersonalityindex_007d-directive_002c-TIC6X-2219"></a><br><dt><code>.personalityindex </code><var>index</var><dd>Sets the personality routine for the current function to the ABI specified
compact routine number <var>index</var>
<p><a name="index-g_t_0040code_007b_002epersonality_007d-directive_002c-TIC6X-2220"></a><br><dt><code>.personality </code><var>name</var><dd>Sets the personality routine for the current function to <var>name</var>.
<p><a name="index-g_t_0040code_007b_002escomm_007d-directive_002c-TIC6X-2221"></a><br><dt><code>.scomm </code><var>symbol</var><code>, </code><var>size</var><code>, </code><var>align</var><dd>Like <code>.comm</code>, creating a common symbol <var>symbol</var> with size <var>size</var>
and alignment <var>align</var>, but unlike when using <code>.comm</code>, this symbol
will be placed into the small BSS section by the linker.
