Module Name: src
Committed By: joerg
Date: Thu Jun 16 13:44:56 UTC 2011
Modified Files:
src/sys/lib/libsa: stand.h
Log Message:
Add an optional MD calling convention flag for use in libsa when space
optimisation is critical. Use this on i386 to switch to register passing
calling convention for the file system entry points and most assembler
call backs that have to preserve at least 3 registers.
