Syntax:

• PRAGMA_SYMBOL SYM SYM0 SYM1 SYM2 offset

Description:

The pragma symbol instruction defines a new symbol "sym", in terms of given symbols: sym0, sym1, sym2 and an offset as:

	sym = sym0 + sym1 - sym2 + offset

The offset is a 32-bit integer, and the symbols: sym0, sym1, sym2, can assume the label "ZERO" for the value zero.

Microcode Pattern:

Takes no cycles to execute.
    Example: PRAGMA_SYMBOL DCA_sss ZERO sss DCL_START1 0x300

Example :

PRAGMA_SYMBOL DCA_sss ZERO sss DCL_START1 0x300

 
Defines a new symbol "DCA_sss" which is the dynamic cache address of the symbol "sss".
The value of this new symbol is given by:

	DCA_sss = 0 + sss - DCL_START1 + 0x300

In the above equation, "sss - DCL_START1" is the number of instructions between the 
symbol sss and the symbol delimiting the start of the dynamic cache block: 

	DCL_START1 (see the microcode above)

and 0x300 is the start address of the section of the instruction cache where the dynamic
cache block is loaded.
