builtin_sac (Continued)
builtin_sacr
builtin_sftac
sac
An error message will be displayed if:
• the result is not an accumulator register
• the shift value is not a literal within range
Shifts value by shift (a literal between -8 and 7) and returns the value
which is rounded using the rounding mode determined by the
CORCONbits.RND control bit.
For example:
Might generate:
int __builtin_sacr(int value, int shift);
value
shift
Returns the shifted result to CORCON register.
sacr
An error message will be displayed if:
• the result is not an accumulator register
• the shift value is not a literal within range
Shifts accumulator by shift. The valid shift range is -16 to 16.
For example:
Might generate:
int __builtin_sftac(int shift);
shift
Returns the shifted result to an accumulator.
sftac
An error message will be displayed if:
• the result is not an accumulator register
• the shift value is not a literal within range
register int value asm("A");
int result;
result = __builtin_sac(value,3);
sac.r A, #3, w0
register int result asm("A");
int i;
result = __builtin_sftac(i);
sftac A, w0
Integer number to be shifted.
