| <dl><dt><code>-isa=sh4 | sh4a</code><dd>Specify the sh4 or sh4a instruction set. |
| <br><dt><code>-isa=dsp</code><dd>Enable sh-dsp insns, and disable sh3e / sh4 insns. |
| <br><dt><code>-isa=fp</code><dd>Enable sh2e, sh3e, sh4, and sh4a insn sets. |
| <br><dt><code>-isa=all</code><dd>Enable sh1, sh2, sh2e, sh3, sh3e, sh4, sh4a, and sh-dsp insn sets. |
| <br><dt><code>-isa=shmedia | -isa=shcompact</code><dd>Specify the default instruction set. <code>SHmedia</code> specifies the |
| 32-bit opcodes, and <code>SHcompact</code> specifies the 16-bit opcodes |
| compatible with previous SH families. The default depends on the ABI |
| selected; the default for the 64-bit ABI is SHmedia, and the default for |
| the 32-bit ABI is SHcompact. If neither the ABI nor the ISA is |
| specified, the default is 32-bit SHcompact. |
| |
| <p>Note that the <code>.mode</code> pseudo-op is not permitted if the ISA is not |
| specified on the command line. |
| |
| <p><a name="index-SH64-ABI-options-1601"></a><a name="index-ABI-options_002c-SH64-1602"></a><br><dt><code>-abi=32 | -abi=64</code><dd>Specify the default ABI. If the ISA is specified and the ABI is not, |
| the default ABI depends on the ISA, with SHmedia defaulting to 64-bit |
| and SHcompact defaulting to 32-bit. |
| |
| <p>Note that the <code>.abi</code> pseudo-op is not permitted if the ABI is not |
| specified on the command line. When the ABI is specified on the command |
| line, any <code>.abi</code> pseudo-ops in the source must match it. |
| |
| <br><dt><code>-shcompact-const-crange</code><dd>Emit code-range descriptors for constants in SHcompact code sections. |
| |
| <br><dt><code>-no-mix</code><dd>Disallow SHmedia code in the same section as constants and SHcompact |
| code. |
| |
| <br><dt><code>-no-expand</code><dd>Do not expand MOVI, PT, PTA or PTB instructions. |
| |
| <br><dt><code>-expand-pt32</code><dd>With -abi=64, expand PT, PTA and PTB instructions to 32 bits only. |
| |
| <br><dt><code>-h-tick-hex</code><dd>Support H'00 style hex constants in addition to 0x00 style. |
