* Use new M_TERMINATOR_FLAG flag
* Add ::Void flag on several instructions so def-use info is correct!
* Implement MANY FP instructions
* Finalize pseudo FP instructions
* Add set of Pseudo FP instruction description flags
* Add support for MOVim instrs
* Add support for 64 bit support instrs, like adc sbb, etc
* Add conditional move
llvm-svn: 5229
* Add support for the constant pool & constant pool indices
* Add support for MRMS?m instructions
* Fix FP Prefix emission
* Add support for global addresses and external symbols
llvm-svn: 5224
* Support arbitrary FP constants
* Fix bugs in frame layout for function calls and incoming arguments
* Insert copies for constant arguments to PHI nodes into the BOTTOM of
predecessor blocks, not the top.
* Implement _floating point_ support: setcc, return, load, store, cast
* Fix several bugs in the cast instruction
* Abstract out call emission and load/store for FP
* Implement malloc/free without previous lowering pass.
* Make use of new forms of MachineOperand
* Implement _long_ support!
* Fix many bugs in FP support
* Change branch from je/jne to je/jmp
* Simplify code generated for GEP instructions
llvm-svn: 5223
* Convert to use PHIElimination pass
* Don't spill values which have just been reloaded (big win reducing spills)
* Add experimental support for eliminating spills before TwoAddress
instructions. It currently is broken so it is #ifdef'd out.
* Use new "is terminator" flag on instructions instead of looking for
branches and returns explicitly.
llvm-svn: 5219
* Add new isPCRelative modifier flag which should be used in place of MO_PCRelativeDisp type.
* Fix a bug in isPhysicalRegister
* Add new setOpcode and RemoveOperand methods
llvm-svn: 5209
* Use new FunctionFrameInfo object to manage stack slots instead of doing
it directly
* Adjust to new MRegisterInfo API
* Don't take a TM as a ctor argument
* Don't keep track of which callee saved registers are modified
* Don't emit prolog/epilog code or spill/restore code for callee saved regs
* Use new allocation_order_begin/end iterators to simplify dramatically the
logic for picking registers to allocate
* Machine PHI nodes can no longer contain constant arguments
* Use a bitvector to keep track of registers used instead of a set
* Fix problem where explicitly referenced registers would be added to
regsused set and never removed
llvm-svn: 5196
* Use new FunctionFrameInfo object to manage stack slots instead of doing
it directly
* Adjust to new MRegisterInfo API
* Don't take a TM as a ctor argument
* Don't keep track of which callee saved registers are modified
* Don't emit prolog/epilog code or spill/restore code for callee saved regs
* Use new allocation_order_begin/end iterators to simplify dramatically the
logic for picking registers to allocate
* Machine PHI nodes can no longer contain constant arguments
llvm-svn: 5195
* Include contents of X86RegisterClasses.cpp into here
* Adjustments to register api to work with new frame manager
* Eliminate moveImm2Reg, getFramePointer, and getStackPointer
* Cleanup and simplify prolog/epilog code generation
* Prolog/epilog are MUCH more efficient now.
