9.29.1 Options

-isa=sh4 | sh4a

Specify the sh4 or sh4a instruction set.

-isa=dsp

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

-isa=fp

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

-isa=all

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

-isa=shmedia | -isa=shcompact

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.

-abi=32 | -abi=64

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.

-shcompact-const-crange

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

-no-mix

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

-no-expand

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

-expand-pt32

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

-h-tick-hex

Support H'00 style hex constants in addition to 0x00 style.
