Can anyone tell me the define of "LABEL" and "mfpc" in irq_stub.S?

[Thomas Doerfler]

Hi,

wow, this was a short posting. maybe a bit too short. It would have
helped if you had written which rtems version you are working on and
which architecture you are interested in.

You can find the definitions in

c/src/lib/libcpu/powerpc/old-exceptions/cpu_asm.S

LABEL is a wrapper to adapt C level identifiers to assembly level labels.

MFPC is a macro to read SRR0 (which holds the previous PC after an
exception).

wkr,
Thomas.
