- * Macro to save all the general purpose registers, the save the stack pointer
- * into the TCB.
- *
- * The first thing we do is save the flags then disable interrupts. This is to
- * guard our stack against having a context switch interrupt after we have already
- * pushed the registers onto the stack - causing the 32 registers to be on the
- * stack twice.
- *
- * r1 is set to zero as the compiler expects it to be thus, however some
- * of the math routines make use of R1.
- *
- * The interrupts will have been disabled during the call to portSAVE_CONTEXT()
- * so we need not worry about reading/writing to the stack pointer.
