     <dl>



     <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.



     <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.
