Benjamin Kramer	7ce42c476a	Force cmov on test so block placement doesn't shuffle the code around. This made the test fail with -mcpu=generic (when building on a non-x86 host). llvm-svn: 154926	2012-04-17 13:55:23 +00:00
Duncan Sands	12f3b3b44f	The DAGCombiner was threading select over pairs of extending loads even if the extension types were not the same. The result was that if you fed a select with sext and zext loads, as in the testcase, then it would get turned into a zext (or sext) of the select, which is wrong in the cases when it should have been an sext (resp. zext). Reported and diagnosed by Sebastien Deldon. llvm-svn: 119728	2010-11-18 20:05:18 +00:00

The DAGCombiner was threading select over pairs of extending loads even

if the extension types were not the same.  The result was that if you
fed a select with sext and zext loads, as in the testcase, then it
would get turned into a zext (or sext) of the select, which is wrong
in the cases when it should have been an sext (resp. zext).  Reported
and diagnosed by Sebastien Deldon.
