1 9.43.3 SH64 Machine Directives
1 ------------------------------
1 
1 In addition to the SH directives, the SH64 provides the following
1 directives:
1 
1 '.mode [shmedia|shcompact]'
1 '.isa [shmedia|shcompact]'
1      Specify the ISA for the following instructions (the two directives
1      are equivalent).  Note that programs such as 'objdump' rely on
1      symbolic labels to determine when such mode switches occur (by
1      checking the least significant bit of the label's address), so such
1      mode/isa changes should always be followed by a label (in practice,
1      this is true anyway).  Note that you cannot use these directives if
1      you didn't specify an ISA on the command line.
1 
1 '.abi [32|64]'
1      Specify the ABI for the following instructions.  Note that you
1      cannot use this directive unless you specified an ABI on the
1      command line, and the ABIs specified must match.
