[L4alpha-cvscommit] CVS: L4Alpha/pal/21264/macros l4_macros.mar,1.9,1.10

[Daniel P. <dp...@us...>]

Update of /cvsroot/l4alpha/L4Alpha/pal/21264/macros
In directory usw-pr-cvs1:/tmp/cvs-serv30550/pal/21264/macros

Modified Files:
	l4_macros.mar 
Log Message:
close_frame now trashes p0 and p5. p5 is always deemed to be scratched when in pal. In this case p0 is also trashed. Previously it was p1.

This should fix the case in ipc send when sending to a non existant TCB. While p0 will still be trashed, it is not used either.
