6.62.4 PRU Pragmas

+ctable_entry index constant_address +
+

Specifies that the PRU CTABLE entry given by index has the value constant_address. This enables GCC to emit LBCO/SBCO instructions when the load/store address is known and can be addressed with some CTABLE entry. For example: 

/* will compile to "sbco Rx, 2, 0x10, 4" */
+#pragma ctable_entry 2 0x4802a000
+*(unsigned int *)0x4802a010 = val;
