8.28.1 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, andSHcompact
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.
