M68hc1x Options
---------------
These are the `-m' options defined for the 68hc11 and 68hc12
microcontrollers. The default values for these options depends on
which style of microcontroller was selected when the compiler was
configured; the defaults for the most common choices are given below.
`-m6811'
`-m68hc11'
Generate output for a 68HC11. This is the default when the
compiler is configured for 68HC11-based systems.
`-m6812'
`-m68hc12'
Generate output for a 68HC12. This is the default when the
compiler is configured for 68HC12-based systems.
`-mauto-incdec'
Enable the use of 68HC12 pre and post auto-increment and
auto-decrement addressing modes.
`-mshort'
Consider type `int' to be 16 bits wide, like `short int'.
`-msoft-reg-count=COUNT'
Specify the number of pseudo-soft registers which are used for the
code generation. The maximum number is 32. Using more pseudo-soft
register may or may not result in better code depending on the
program. The default is 4 for 68HC11 and 2 for 68HC12.
