The following example is non-conforming, because the \kcode{flush}, \kcode{barrier},
|
|
\kcode{taskwait}, and \kcode{taskyield} directives are stand-alone directives
|
|
and cannot be the immediate substatement of an \bcode{if} statement.

The following example is non-conforming, because the \kcode{flush}, \kcode{barrier},

\kcode{taskwait}, and \kcode{taskyield} directives are stand-alone directives

and cannot be the action statement of an \bcode{if} statement or a labeled branch

The following version of the above example is conforming because the \kcode{flush},
|
|
\kcode{barrier}, \kcode{taskwait}, and \kcode{taskyield} directives are enclosed
|
|
in a compound statement.

The following example is conforming because the \kcode{flush}, \kcode{barrier},

\kcode{taskwait}, and \kcode{taskyield} directives are enclosed in an \bcode{if}
|
|
construct or follow the labeled branch target.
