Subject: Include the source type in SCEV cast expression debug output, and
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=36b8e53fe069862627cd06d82767a4253e24638d;p=oota-llvm.git

Include the source type in SCEV cast expression debug output, and
print sext, zext, and trunc, instead of signextend, zeroextend,
and truncate, respectively, for consistency with the main IR.
