| <p><a name="index-Symbols_002c-built_002din_002c-CRIS-722"></a><a name="index-Symbols_002c-CRIS_002c-built_002din-723"></a><a name="index-CRIS-built_002din-symbols-724"></a><a name="index-Built_002din-symbols_002c-CRIS-725"></a> |
| Some symbols are defined by the assembler. They're intended to |
| be used in conditional assembly, for example: |
| <pre class="smallexample"> .if ..asm.arch.cris.v32 |
| <var>code for CRIS v32</var> |
| .elseif ..asm.arch.cris.common_v10_v32 |
| <var>code common to CRIS v32 and CRIS v10</var> |
| .elseif ..asm.arch.cris.v10 | ..asm.arch.cris.any_v0_v10 |
| <var>code for v10</var> |
| .else |
| .error "Code needs to be added here." |
| .endif |
| </pre> |
| <p>These symbols are defined in the assembler, reflecting |
| command-line options, either when specified or the default. |
| They are always defined, to 0 or 1. |
| <dl> |
| <dt><code>..asm.arch.cris.any_v0_v10</code><dd>This symbol is non-zero when <samp><span class="option">--march=v0_v10</span></samp> is specified |
| or the default. |
| |
| <br><dt><code>..asm.arch.cris.common_v10_v32</code><dd>Set according to the option <samp><span class="option">--march=common_v10_v32</span></samp>. |
| |
| <br><dt><code>..asm.arch.cris.v10</code><dd>Reflects the option <samp><span class="option">--march=v10</span></samp>. |
| |
| <br><dt><code>..asm.arch.cris.v32</code><dd>Corresponds to <samp><span class="option">--march=v10</span></samp>. |
| </dl> |
| |
| <p>Speaking of symbols, when a symbol is used in code, it can have |
| a suffix modifying its value for use in position-independent |
| code. See <a href="CRIS_002dPic.html#CRIS_002dPic">CRIS-Pic</a>. |
