Subject: [SCEV] Fix GCC 4.8.0 ICE in lambda function
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=25faeeb8fe6eaaf3cc5729e375e52e8a7402a6f6;p=oota-llvm.git

[SCEV] Fix GCC 4.8.0 ICE in lambda function

Rewrite some code to not use a lambda function. The non-lambda code is just
about as clean as the original, and not any longer. The lambda function causes
an internal compiler error in GCC 4.8.0, and it is not worth breaking support
for that compiler over this. NFC.
