Evan Cheng 6fd599fa69 Add a target lowering hook to control whether it's worthwhile to compress fp constant. ... For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47931 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-05 01:30:59 +00:00
