# The ARCH variable specifies which -xarch based flag for example is used
# on the build tools. Currently v9, v8plus, and amd64 are supported. The default is
# v9. The v8plus target is only used for the cosim targets. Some people
# refer to this flag as the platform you are compiling for. When you change
# this, look at the BITS, CFLAGS, and ASFLAGS below to see if change is
# needed there too.# Note for the sparc v8 and v8plus we leave out the last
# letter a b or c which tells which subset of the instructiuon set is
# available (vis 1, vis2, ...). That part we assume to be fixed.
