Constants in SH-4 Inline Assembly (Windows CE 5.0)
Because the SH-4 Series assembler does not support character constants, SH-4 inline assembly supports only integer constants.
Express integer constants with a prefix that indicates the radix. The radix prefix indicates the base of the constant. The following table lists integer types and their radix prefix.
| Integer Base | Prefix |
|---|---|
| Binary Numbers | The radix indicator B' or b' plus a binary constant |
| Octal Numbers | The radix indicator Q' or q' or 0 plus an octal constant |
| Decimal Numbers | The radix indicator D' or d' plus a decimal constant |
| Hexadecimal Numbers | The radix indicator H' or h' or 0x Or OX plus a hexadecimal constant |
The radix indicator and the constant value must be written with no intervening space.
The following code example shows how to define integer constants in a __asm block.
__asm("cmp/eq #0xff, r0" ); // Hexadecimal number
__asm("cmp/eq #H'ff, r0" ); // Hexadecimal number
__asm("cmp/eq #255, r0" ); // Decimal number
__asm("cmp/eq #d'255, r0" ); // Decimal number
__asm("cmp/eq #b'10, r0" ); // Binary number
__asm("cmp/eq #B'10, r0" ); // Binary number
__asm("cmp/eq #Q'10, r0" ); // Octal number
__asm("cmp/eq #010, r0" ); // Octal number
