Syntax:

• PRAGMA_STK_LEVEL n

Description:

The stack level pragma forces the shaker's book-keeping of the stack level to the value of n. This pragma can be used to force conditioning (if set to a non-zero value) or to release conditioning (if set to 0) of the subsequent instructions.

Microcode Pattern:

Takes 0 cycles to execute.
    Example: PRAGMA_STK_LEVEL 0 (Microcode for example below)
