* Changed the encoding of X86 floating point stack operations where both operandsKevin Enderby2010-05-251-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | are st(0). These can be encoded using an opcode for storing in st(0) or using an opcode for storing in st(i), where i can also be 0. To allow testing with the darwin assembler and get a matching binary the opcode for storing in st(0) is now used. To do this the same logical trick is use from the darwin assembler in converting things like this: fmul %st(0), %st into this: fmul %st(0) by looking for the second operand being X86::ST0 for specific floating point mnemonics then removing the second X86::ST0 operand. This also has the add benefit to allow things like: fmul %st(1), %st that llvm-mc did not assemble. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104634 91177308-0d34-0410-b5e6-96231b3b80d8
