Subject: Define BYTE_ORDER on Solaris.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=01ef4f6982451e6a7c00a713d9ae677d3a15d042

Define BYTE_ORDER on Solaris.

Solaris doesn't have an endian.h header, but SPARC is the only
big-endian architecture that runs Solaris, so just use that to detect
endianness at compile time.
