Description

Another case of an obscure volatile boolean
c/src/lib/libbsp/powerpc/score603e/console/consolebsp.h:
...

volatile rtems_boolean Is_TX_active;

...

IMO, this volatile is wrong and should be removed.

Replying to comment:1:

This looks like a valid use of a volatile bool to me.

Looks like a poor man's mutex to me ;)

It indicates whether or
not the hardware transmitter is currently transmitting a character and thus
could be changed at task or ISR level.

Interprocess communication by passing the address of a local variable?
