3.4.9 CLREX
Clear Exclusive.
3.4.9.1 Syntax
CLREX{cond}
where:
cond
is an optional condition code, see Section 3.3.7 (p. 43) .
3.4.9.2 Operation
Use CLREX to make the next STREX, STREXB, or STREXH instruction write 1 to its destination register and
fail to perform the store. It is useful in exception handler code to force the failure of the store exclusive if
the exception occurs between a load exclusive instruction and the matching store exclusive instruction
in a synchronization operation.
See Section 2.2.7 (p. 20) for more information.
3.4.9.3 Condition flags
These instructions do not change the flags.
3.4.9.4 Examples
