Subject: [mips] Actually mark that the default case is unreachable as this switch
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9a0be5bfd9b49837ab1ba86fdd9b2e121d8af5eb;p=oota-llvm.git

[mips] Actually mark that the default case is unreachable as this switch
is over a subset of condition codes.

This fixes the -Werror build which warns about use of uninitialized
variables in the default case.
