Chris Lattner 3828c2fa80 revert a hunk of r82018 that wasn't supposed to go in yet.

Chris Lattner e18a53890a apparently russians are really hard to sort or something!

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.

Dan Gohman 3b7ce109ec Don't sink gep operators through phi nodes if the result would require 
more than one phi, since that leads to higher register pressure on
entry to the phi. This is especially problematic when the phi is in
a loop header, as it increases register pressure throughout the loop.

llvm-svn: 81993
 2009-09-16 02:01:52 +00:00
Sean Callanan 1c28c4db58 Removed a few instructions that were already 
covered by other definitions.

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();

Chris Lattner 6a833f6806 add a helper method for creating MCSymbol and MCSymbolRefExpr at 
the same time.

 2009-09-16 01:26:31 +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 d106abfce7 Eliminate AsmPrinter::EmitExternalGlobal, inlining its (now) 
one implementation into its one caller.  This eliminates a totally
awesome and gratuitous hack where we casted a Function* to 
GlobalVariable*.

llvm-svn: 81967

Bob Wilson 4ed397c141 Neon does not support vector divide or remainder. Expand them.

 2009-09-16 00:17:28 +00:00
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).

Chris Lattner dd5a989034 eliminate the horrid AsmPrinter::getGlobalLinkName method, inlining 
it into all of its call sites and simplifying them.

Sean Callanan f8f6479388 Added far return instructions (that is, returns to 
code in other segments) to the Intel instruction
tables.
