Daniel Dunbar 0e42dc0dac MC/X86: Add a dummy implementation of MCFixup generation for hacky X86 MCCodeEmitter. 
llvm-svn: 95709
 2010-02-09 23:00:03 +00:00
Daniel Dunbar b311a6b3ae MC: First cut at MCFixup, for getting fixup/relocation information out of an MCCodeEmitter.

Bill Wendling bf02536262 Improve comments in the LSDA somewhat. They can be improved much more.

Johnny Chen b618f66c5f Added VMRS/VMSR for disassembly only.

Sean Callanan a36341366b Added AsmWriterInst.cpp to the CMakeList so that 
it builds OK on Visual Studio.

Dale Johannesen 7c7b9a2807 Disable unittests/ADT/BitVectorTest on PPC Darwin. 
It fails with a release build only, for reasons
as yet unknown.  (If there's a better way to Xfail
things here let me know, doesn't seem to be any
prior art in unittests.)

Chris Lattner 8aef06f8eb port encoder enhancements over to the new encoder.

 2010-02-09 21:57:34 +00:00
Sean Callanan b7e8f4a30e Per PR 6219, factored AsmWriterInst and AsmWriterOperand 
out of the AsmWriterEmitter.  This patch does the physical
code movement, but leaves the implementation unchanged. I'll
make any changes necessary to generalize the code in a
separate patch.

Chris Lattner 0c3b66cd87 fix X86 encoder to output [disp] only addresses with no SIB byte 
in X86-32 mode.  This is still required in x86-64 mode to avoid
forming [disp+rip] encoding.  Rewrite the SIB byte decision logic
to be actually understandable.

enable constant 0 offset lowering.

Chris Lattner 45d89644ae revert r95689: getX86RegNum(BaseReg) != N86::ESP is 
a confusing idiom to check for ESP or RSP.

Chris Lattner b06015aa69 move target-independent opcodes out of TargetInstrInfo 
into TargetOpcodes.h.  #include the new TargetOpcodes.h
into MachineInstr.  Add new inline accessors (like isPHI())
to MachineInstr, and start using them throughout the 
codebase.

Jim Grosbach f7279bd10f Radar 7417921 
tMOVCCi pattern only valid for low registers, as the Thumb1 mov immediate to
register instruction only works with low registers. Allowing high registers
for the instruction resulted in the assembler choosing the wide (32-bit)
encoding for the mov, but LLVM though the instruction was only 16 bits wide,
so offset calculations for constant pools became incorrect, leading to
out of range constant pool entries.

Eric Christopher ad1aa86276 Pull these back out, they're a little too aggressive and time 
consuming for a simple optimization.

Lang Hames 48121948dc Fixed a bug in the PBQP allocator's findCoalesces method. 
Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

Eric Christopher 9f85e7eb16 Add a new pass to do llvm.objsize lowering using SCEV. 
Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase
to new directory.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.
