In addition to the SH directives, the SH64 provides the following directives:
.mode [shmedia|shcompact]
.isa [shmedia|shcompact]
Specify the ISA for the following instructions (the two directives are
equivalent). Note that programs such as objdump rely on symbolic
labels to determine when such mode switches occur (by checking the least
significant bit of the label’s address), so such mode/isa changes should
always be followed by a label (in practice, this is true anyway). Note
that you cannot use these directives if you didn’t specify an ISA on the
command line.
.abi [32|64]
Specify the ABI for the following instructions. Note that you cannot use this directive unless you specified an ABI on the command line, and the ABIs specified must match.
