|
Rotates x to the right y times assuming that x has a size of eight bits.
Operation is undefined for the case where the rotation count is greater than the size of the value.
If the rotation count may be greater than the size, mask the count to not exceed the size.
|
unsigned char __rorb(
unsigned char x,
unsigned char y
);
|
__rolw
|
Rotates x to the left y times assuming that x has a size of 16 bits.
Operation is undefined for the case where the rotation count is greater than the size of the value.
If the rotation count may be greater than the size, mask the count to not exceed the size.

unsigned int x,
unsigned char y
);
|
__rorw
|
Rotates x to the right y times assuming that x has a size of 16 bits.
Operation is undefined for the case where the rotation count is greater than the size of the value.
If the rotation count may be greater than the size, mask the count to not exceed the size.

unsigned long long __mulul(
unsigned long x,
unsigned long y
);
|
__mulsl
|
Executes signed multiplication between (signed long long)x and (signed long long)y and returns a 64-bit result. When the -lang=c and -strict_std options are specified, this function is not defined as an intrinsic function.
