2012-01-31Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses aKevin Enderby
symbol from an assignment. In this case the symbol did not have a fragment so MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should just have returned false in that case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149442 91177308-0d34-0410-b5e6-96231b3b80d8

For bit patterns that aren't representable using the 8-bit floating point representation for vmov.f32, but are representable via vmov.i32, treat the .f32 syntax as an alias.
