MSP 430 assemblers.

<em>Warning:</em> in other versions of the <span class="sc">gnu</span> assembler, <code>.file</code> is
used for the directive called <code>.app-file</code> in the MSP 430 support.

MSP 430 assemblers.
<p><a name="index-g_t_0040code_007barch_007d-directive_002c-MSP-430-1758"></a><br><dt><code>.arch</code><dd>Sets the target microcontroller in the same way as the <samp><span class="option">-mmcu</span></samp>
command-line option.
<p><a name="index-g_t_0040code_007bcpu_007d-directive_002c-MSP-430-1759"></a><br><dt><code>.cpu</code><dd>Sets the target architecture in the same way as the <samp><span class="option">-mcpu</span></samp>
command-line option.
<p><a name="index-g_t_0040code_007bprofiler_007d-directive_002c-MSP-430-1760"></a><br><dt><code>.profiler</code><dd>This directive instructs assembler to add new profile entry to the object file.
<p><a name="index-g_t_0040code_007brefsym_007d-directive_002c-MSP-430-1761"></a><br><dt><code>.refsym</code><dd>This directive instructs assembler to add an undefined reference to
the symbol following the directive. The maximum symbol name length is
1023 characters. No relocation is created for this symbol; it will
exist purely for pulling in object files from archives. Note that
this reloc is not sufficient to prevent garbage collection; use a
KEEP() directive in the linker file to preserve such objects.
