Chandler Carruth 16003d0c0c Replace the ad-hoc hashing in GVN with the new hashing infrastructure. ... This implicitly fixes a nasty bug in the GVN hashing (that thankfully could only manifest as a performance bug): actually include the opcode in the hash. The old code started the hash off with the opcode, but then overwrote it with the type pointer. Since this is likely to be pretty hot (GVN being already pretty expensive) I've included a micro-optimization to just not bother with the varargs hashing if they aren't present. I can't measure any change in GVN performance due to this, even with a big test case like Duncan's sqlite one. Everything I see is in the noise floor. That said, this closes a loop hole for a potential scaling problem due to collisions if the opcode were the differentiating aspect of the expression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152025 91177308-0d34-0410-b5e6-96231b3b80d8		2012-03-05 11:29:54 +00:00
