Dan Gohman 722b1eefdb Add support for using the FLAGS result of or, xor, and and instructions
on x86, to avoid explicit test instructions. A few existing tests changed
due to arbitrary register allocation differences.

Anton Korobeynikov 592638ae05 Allow symbols to start from the digit if target requests it. This allows, e.g. pinning
variables to specified absolute address. Make use of this feature for MSP430.

Nate Begeman 1ae49ee7ca Do not try and sink a load whose chain result has more than one use, when
trying to create RMW opportunities in the x86 backend.  This can cause a 
cycle to appear in the graph, since the other uses may eventually feed into
the TokenFactor we are sinking the load below.

Sean Callanan 771a1f1720 Added the ENTER instruction, which sets up a stack
frame, to the Intel instruction tables.

Sean Callanan 0fdee53266 Added the definitions for one-bit left shifts to
the Intel instruction tables.

The patterns will stay blank because ADD reg, reg
is faster, but having the encoding available is
useful for the disassembler.

llvm-svn: 81994

Chris Lattner b866602f06 Big change #1 for personality function references:
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding
fields from MAI: they aren't part of the asm syntax, they are
related to the structure of the object file.

To replace their functionality, add a new 
TLOF::getSymbolForDwarfGlobalReference method which asks targets
to decide how to reference a global from EH in a pc-relative way.

The default implementation just returns the symbol.  The default
darwin implementation references the symbol through an indirect
$non_lazy_ptr stub.  The bizarro x86-64 darwin specialization
handles the weird "foo@GOTPCREL+4" hack.

DwarfException.cpp now uses this to emit the reference to the
symbol in the right way, and this also eliminates another 
horrible hack from DwarfException.cpp:

-    if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL"))
-      O << "-" << MAI->getPCSymbol();

llvm-svn: 81991
2009-09-16 01:46:41 +00:00
Sean Callanan e739ac8900 Added a variety of floating-point and SSE instructions.
All of these do not have patterns (they're for the
disassembler).

Many of the floating-point instructions will probably
be rolled into definitions that have patterns, and may
eventually be superseded by mdefs.  So I put them
together and left a comment.

Chris Lattner 4e465598f0 eliminate the PPC backend's implementation of EmitExternalGlobal
and use PersonalityPrefix/Suffix to achieve the same effect (like
the x86 backend).

This changes the code generated for ppc static mode, but guess what,
we were generating this before:

	.byte	0x9B                                        ; Personality (indirect pcrel sdata4)
	.long	___gxx_personality_v0-.                     ; Personality

which is not correct! (it is not an 'indirect' reference).

Dale Johannesen c092b76d63 Change the marker byte for stubs from 0xcd to 0xce (another form of
interrupt instruction, which shouldn't arise any other way).  0xcd is
also used by JITMemoryManager to initialize the buffer to garbage,
which means it could appear following a noreturn call even when
that is not a stub, confusing X86CompilationCallback2.  PR 4929.

Bob Wilson 967bf27de2 Handle AddrMode4 for Thumb2 in rewriteT2FrameIndex. This occurs for
VLDM/VSTM instructions, and without this check, the code assumes that an
offset is allowed, as it would be with VLDR/VSTR.  The asm printer,
however, silently drops the offset, producing incorrect code.  Since the
address register in this case is either the stack or frame pointer, the
spill location ends up conflicting with some other stack slot or with
outgoing arguments on the stack.

Dan Gohman 520a6856ba Don't pull a load through a callseq_start if the load's chain
has multiple uses, as one of the other uses may be on a path
to a different node above the callseq_start, because that
leads to a cyclic graph. This problem is exposed when
-combiner-global-alias-analysis is used. This fixes PR4880.

different test cases, one for x86 and one for arm.

Chris Lattner 11b2fc9ea4 Change MCAsmStreamer to take an MCInstPrinter instead of a

Chris Lattner 6ccf7ed4be X86MCInstLower::Lower should only not emit anything to OutStreamer,

2009-09-11 01:01:31 +00:00
Evan Cheng 3cad6283b8 It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

Chris Lattner 321bc99a74 remove DebugLoc from MCInst and eliminate "Comment printing" from
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

Chris Lattner 716a8c92d0 hoist the call to processDebugLoc out of the generated
asm printer into the "printInstruction" routine.  This
fixes a problem where the experimental asmprinter would
drop debug labels in some cases, and fixes issues on ppc/xcore
where pseudo instructions like "mr" didn't get debug locs properly.

It is annoying that this moves the call from one place into each
target, but a future set of more invasive refactorings will fix
that problem.

Bill Wendling 39bb29f7fe - Add target lowering methods to get the preferred format for the FDE and LSDA
encodings.
- Make some of the values emitted by the FDEs dependent upon the pointer
  size. This is in line with how GCC does things. And it has the benefit of
  working for Darwin in 64-bit mode now.

Daniel Dunbar 981a71c302 llvm-mc/X86: Implement single instruction encoding interface for MC.
- Note, this is a gigantic hack, with the sole purpose of unblocking further
   work on the assembler (its also possible to test the mathcer more completely
   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc
   (although some encodings are probably incorrect). This is a testament to the 
   beauty of X86's MachineInstr, no doubt! ;)

2009-08-27 00:31:47 +00:00
Dan Gohman f1abb5511b Expand i8 selects into control flow instead of 16-bit conditional
moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.
