Currently, when using an instruction that is not supported on the currently selected architecture, the LLVM assembler is likely to diagnose an "invalid operand" instead of a "missing feature". This is because many operands require a custom parser in order to be processed correctly, and if an instruction is not available according to the current feature set, the generated parser code will also not detect the associated custom operand parsers. Fixed by temporarily enabling all features while parsing operands. The missing features will then be correctly detected when actually parsing the instruction itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@285575 91177308-0d34-0410-b5e6-96231b3b80d8
