Attributes can be specified in declarations or definitions of functions or variables by using
keywords (_ _interrupt, _ _indirect, _ _entry, _ _abs8, _ _abs16, _ _regsave, _ _noregsave,
_ _inline, or _ _global_register).
The vector table of functions can be created automatically when vect is specified by #pragma
interrupt, #pragma indirect, #pragma entry, _ _interrupt, _ _indirect, or _ _entry.
Memory access of a variable at even-numbered byte boundary is guaranteed with
_ _evenaccess specified.
_ _regparam2 and _ _regparam3 can be used to specify the number of register parameters in
a function.
Options can be specified on function by function basis by using #pragma option.
Optimizes address calculation code of arrays or structures by using _ _near8 or _ _near16.
However, the pointer size is not changed.
Optimizes stack address calculation code of stack areas by using stack.
The following intrinsic functions were added.
In the new version, double=float can be specified so that data declared as double-precision
type and floating-point constants are both regarded as float type.
When a function declared with #pragma noregsave or _ _noregsave is called, the contents of
the registers are guaranteed by the calling function.
Unsigned overflow operations
Added and Improved Compiler Features
