Specify the sh4 or sh4a instruction set.

Enable sh-dsp insns, and disable sh3e / sh4 insns.

Enable sh2e, sh3e, sh4, and sh4a insn sets.

Enable sh1, sh2, sh2e, sh3, sh3e, sh4, sh4a, and sh-dsp insn sets.

Specify the default instruction set. SHmedia specifies the 32-bit opcodes, and SHcompact 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.

Note that the .mode pseudo-op is not permitted if the ISA is not specified on the command line.

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.

Note that the .abi 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 .abi pseudo-ops in the source must match it.

Emit code-range descriptors for constants in SHcompact code sections.

Disallow SHmedia code in the same section as constants and SHcompact code.

Do not expand MOVI, PT, PTA or PTB instructions.

With -abi=64, expand PT, PTA and PTB instructions to 32 bits only.
