rip out the 'heinous' x86 MCCodeEmitter implementation. We still have the templated X86 JIT emitter, *and* the almost-copy in X86InstrInfo for getting instruction sizes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96059 91177308-0d34-0410-b5e6-96231b3b80d8

Updated the llvm-mc disassembler C API to support for the X86 target. rdar://10873652 As part of this I updated the llvm-mc disassembler C API to always call the SymbolLookUp call back even if there is no getOpInfo call back. If there is a getOpInfo call back that is tried first and then if that gets no information then the SymbolLookUp is called. I also made the code more robust by memset(3)'ing to zero the LLVMOpInfo1 struct before then setting SymbolicOp.Value before for the call to getOpInfo. And also don't use any values from the LLVMOpInfo1 struct if getOpInfo returns 0. And also don't use any of the ReferenceType or ReferenceName values from SymbolLookUp if it returns NULL. rdar://10873563 and rdar://10873683 For the X86 target also fixed bugs so the annotations get printed. Also fixed a few places in the ARM target that was not producing symbolic operands for some instructions. rdar://10878166 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151267 91177308-0d34-0410-b5e6-96231b3b80d8

Changed the encoding of X86 floating point stack operations where both operands 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

fix PR8686, accepting a 'b' suffix at the end of all the setcc instructions. I choose to handle this with an asmparser hack, though it could be handled by changing all the instruction definitions to allow be "setneb" instead of "setne".

Fix an inconsistency in the x86 backend that led it to reject "calll foo" on x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly named "callq", so this only impacted x86-32.

Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc will accept versions that the darwin assembler allows. Forms ending in "pi" and forms without all the operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117427 91177308-0d34-0410-b5e6-96231b3b80d8

go to great lengths to work around a GAS bug my previous patch exposed: GAS doesn't accept "fcomip %st(1)", it requires "fcomip %st(1), %st(0)" even though st(0) is implicit in all other fp stack instructions. Fortunately, there is an alias for fcomip named "fcompi" and gas does accept the default argument for the alias (boggle!). As such, switch the canonical form of this instruction to "pi" instead of "ip". This makes the code generator and disassembler generate pi, avoiding the gas bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118356 91177308-0d34-0410-b5e6-96231b3b80d8
