-int_size

Allows changing the format for signed/unsigned int (by default 16-bit).

Syntax

  -int_size 1 | 2 | 4

The arguments are as follows:

1 : 8-bit

2 : 16-bit

4 : 32-bit

Default

2

Defines

  __INT_IS_8BIT__

  __INT_IS_16BIT__

  __INT_IS_32BIT__

Remarks

For integrity and compliance to ANSI, the following must hold:

  sizeof(short) <= sizeof(int) <= sizeof(long)

Note: Be careful if you change type sizes. Type sizes must be consistent over the whole application. The libraries delivered with the compiler are compiled with the standard type settings. Also, underflows or overflows might occur following type configuration, for example when you assign a value too large to an object which is now smaller.
