Evan Cheng 27c3702267 Fix lfence and mfence encoding. These look like MRM5r and MRM6r instructions except they do not have any operands. The RegModRM byte is encoded with register number 0.

Anton Korobeynikov f16134141d Allow inline asm nodes with empty bodies inside JIT. 
This unbreaks explicit reg vars inside JIT, which are
implemented in such hacky way :)

Dale Johannesen d4a5e8f74a In the absence of a linker to build the GOT, use the 32-bit 
non_lazy_ptr mechanism on x86-64 Darwin JIT.  Fixes a bunch
of last night's failures.

 2008-08-12 18:23:48 +00:00
Dale Johannesen dafdbf77b3 Some fixes for x86-64 JIT. Make it use small code 
model, except for external calls; this makes
addressing modes PC-relative.  Incomplete.

The assertion at the top of Emitter::runOnMachineFunction
was obviously bogus (always true) so I removed it.
If someone knows what the correct test should be to cover
all the various targets, please fix.

Dan Gohman fb19f9402b Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminating 
the need for a flavor operand, and add a new SDNode subclass,
LabelSDNode, for use with them to eliminate the need for a label id
operand.

Change instruction selection to let these label nodes through
unmodified instead of creating copies of them. Teach the MachineInstr
emitter how to emit a MachineInstr directly from an ISD label node.

This avoids the need for allocating SDNodes for the label id and
flavor value, as well as SDNodes for each of the post-isel label,
label id, and label flavor.

Evan Cheng 974722b16f runOnMachineFunction should set IsPIC because relocation model may have been changed.

Dan Gohman eabd647cd5 Change target-specific classes to use more precise static types. 
This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Evan Cheng 6db4b4cc65 Fix x86-64 encoding bug. REX prefix must always follow 0x0F prefix. For example, extractps in 64bit mode: 66 REX 0F 3A 17, not 66 0F 3A REX 17.

Andrew Lenharth 0070dd1de3 Add lock prefix support to x86. Also add the instructions necessary for the atomic ops. They are still marked pseudo, since I cannot figure out what format to use, but they are the correct opcode.

Chris Lattner 03ad885039 rename TargetInstrDescriptor -> TargetInstrDesc. 
Make MachineInstr::getDesc return a reference instead
of a pointer, since it can never be null.

Chris Lattner f376c99ea0 rename hasVariableOperands() -> isVariadic(). Add some comments.

Chris Lattner b0d06b4381 Move a bunch more accessors from TargetInstrInfo to TargetInstrDescriptor 
llvm-svn: 45680
 2008-01-07 03:13:06 +00:00
Chris Lattner a98c679de0 Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects 
that it is cheap and efficient to get.

Move a variety of predicates from TargetInstrInfo into 
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around.  Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.

Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.

Evan Cheng 563fcc3428 Change MachineRelocation::DoesntNeedFnStub to NeedStub. This fields will be used 
for non-function GV relocations that require function address stubs (e.g. Mac OS X in non-static mode).

llvm-svn: 45515
 2008-01-02 23:38:59 +00:00
Chris Lattner a5bb370aa4 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.
