68K

PowerPC

MIPS

mac68k  

Aligns every field on a 2-byte boundaries, unless a field is only 1-byte long. This is the standard alignment for 68K Macintosh computers.  

mac68k4byte  

Aligns every field on 4-byte boundaries.  

power  

Align every field on its natural boundary. This is the standard alignment for Power Macintosh computers. For example, it aligns a character on a 1-byte boundary and a 16-bit integer on a 2-byte boundary. The compiler applies this alignment recursively to structured data and arrays containing structured data. So, for example, it aligns an array of structured types containing an 4-byte floating point member on an 4-byte boundary.  

native  

Aligns every field using the standard alignment. It is equivalent to using mac68k for 68K Macintosh computers and power for Power Macintosh computers.  

packed  

Aligns every field on a 1-byte boundary. It is not available in any settings panel. This alignment will cause your code to crash or run slowly on many platforms. Use it with caution.  

reset  

Resets the option to the value in the previous #pragma options align statement, if there is one, or to the value in the 68K or PPC Processor settings panel.
