Function Documentation

cpu_AtomicAdd()

intptr_t cpu_AtomicAdd	(	volatile intptr_t *	location,
		intptr_t	increment
	)

Routines specific to E2K (MCST Elbrus 2000)

add a signed value to a variable without the possibility of interference from other threads/CPUs.

cpu_CAS()

bool cpu_CAS	(	volatile intptr_t *	location,
		intptr_t	expected,
		intptr_t	newValue
	)

atomic "compare and swap".

Parameters

location	address of the word to compare and possibly overwrite
expected	its expected value
newValue	the value with which to replace it

Returns

false if the target word doesn't match the expected value, otherwise true (also overwriting the contents of location)

cpu_CAS64()

bool cpu_CAS64	(	volatile i64 *	location,
		i64	expected,
		i64	newValue
	)

cpu_IdentifierString()

const char* cpu_IdentifierString

(

)

Returns

string identifying the CPU (usually a cleaned-up version of the brand string)
