This eliminates a FIXME and is on the path to finishing: rdar://7639610 - eliminate encoding and asm info for TAILJMPd TAILJMPr TAILJMPn, etc. However, I can't eliminate the encodings for these instructions because the JIT still exists and has its own copy of the encoder, sigh. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107946 91177308-0d34-0410-b5e6-96231b3b80d8

* make mcinstlower remove all but the first operand to CALL64pcrel32.Chris Lattner2010-05-181-1/+11
| | | | | | | | | | | | | The register use operands (e.g. the first argument is passed in a register) is currently being modeled as a normal register use, instead of correctly being an implicit use. This causes the operand to get propagated onto the mcinst, which was causing the encoder to emit a rex prefix byte, which generates an invalid call.

* MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.Daniel Dunbar2010-03-151-17/+12
| | | | | | | - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue. - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98592 91177308-0d34-0410-b5e6-96231b3b80d8
