This patch changes X86TargetLowering::LowerCall() to skip tail call optimization, if the called function is a global or external symbol. Patch by Dimitry Andric!

This was found by a perniciously unstable sort implementation used to flush out buggy uses of the algorithm. The fundamental idea is that findCommonType should return the best common type it can find across all of the slices in the range. There were two bugs here previously: 1) We would accept an integer type smaller than a byte-width multiple, and if there were different bit-width integer types, we would accept the first one. This caused an actual failure in the testcase updated here when the sort order changed. 2) If we found a bad combination of types or a non-load, non-store use before an integer typed load or store we would bail, but if we found the integere typed load or store, we would use it. The correct behavior is to always use an integer typed operation which covers the partition if one exists. While a clever debugging sort algorithm found problem #1 in our existing test cases, I have no useful test case ideas for #2. I spotted in by inspection when looking at this code. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_34@195217 91177308-0d34-0410-b5e6-96231b3b80d8
