These options control some compilation choices specific to the Hitachi
H8/500:
-mspace
- When a tradeoff is available between code size and speed, generate
smaller code.
-mspeed
- When a tradeoff is available between code size and speed, generate
faster code.
-mint32
- Make
int
data 32 bits by default.
-mcode32
- Compile code for a 32 bit address space.
-mdata32
- Compile data for a 32 bit address space.
-mtiny
- Compile both data and code sections using the same 16-bit address space.
-msmall
- Compile both data and code sections for 16-bit address spaces, but use
different link segments.
-mmedium
- Compile code for a 32-bit address space, but data for a 16-bit address
space. This is the same as specifying `-mcode32' without
`-mdata32'.
-mcompact
- Compile data for a 32-bit address space, but code for a 16-bit address
space. This is the same as specifying `-mdata32' without
`-mcode32'.
-mbig
- Compile both data and code sections for 32-bit address spaces. This is
the same as specifying both `-mdata32' and `-mcode32'.
