* convert the new matcher to check intermediate nodes for a singleChris Lattner2010-02-165-47/+32
| | | | | | | | | use and only call IsProfitableToFold/IsLegalToFold on the load being folded, like the old dagiselemitter does. This substantially simplifies the code and improves opportunities for sharing. llvm-svn: 96368
* change dag isel emitter to only call 'IsProfitableToFold' on nodesChris Lattner2010-02-161-3/+13
| | | | | | | | with chains. On interior nodes that lead up to them, we just directly check that there is a single use. This generates slightly more efficient code. llvm-svn: 96366
* Fix pr6111: Avoid using the LR register for the target address of an indirectBob Wilson2010-02-163-4/+27
| | | | | | | | branch in ARM v4 code, since it gets clobbered by the return address before it is used. Instead of adding a new register class containing all the GPRs except LR, just use the existing tGPR class. llvm-svn: 96360
* Introduce isOpaqueTy and use it rather than isa<OpaqueType>. Also, move someDuncan Sands2010-02-1610-34/+38
| | | | | | methods to try to have the type predicates be more logically positioned. llvm-svn: 96349
* There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands2010-02-1670-581/+585
| | | | | | | and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. llvm-svn: 96344

* The code section for an ISR has a specific address.Sanjiv Gupta2010-02-164-4/+23
| | | | | | Currently, whether a function is ISR or not is encoded in the section attribute for that function. llvm-svn: 96322
* Handle DBG_VALUE mixed with labels when doing PHIDale Johannesen2010-02-161-1/+18
| | | | | | | elimination. Before a DBG_VALUE could affect codegen. The solution here is imperfect and not final. llvm-svn: 96318
* Drop support for the InReg attribute on the ppc backend. This was used byRafael Espindola2010-02-161-16/+1
| | | | | | | llvm-gcc but has been replaced with pad argument which don't need any special backend support. llvm-svn: 96312
* Split the main for-each-use loop again, this time for GenerateTruncates,Dan Gohman2010-02-162-1/+63
| | | | | | | as it also peeks at which registers are being used by other uses. This makes LSR less sensitive to use-list order. llvm-svn: 96308
* Reapply 96294; now that I've gotten around to lookingDale Johannesen2010-02-161-4/+26
| | | | | | | at older buildbot messages, I see the failure predates this patch. llvm-svn: 96307
* Apply patch from http://llvm.org/bugs/attachment.cgi?id=4136 now that PR5004 isBill Wendling2010-02-161-1/+5

* Something broke. Hard to believe it was this patchDale Johannesen2010-02-161-26/+4
| | | | | | | but it's harder to believe it's the other candidate, so reverting. Temporarily I hope. llvm-svn: 96303

* Put repeated empty pattern into the AQI instruction class.Bob Wilson2010-02-151-49/+19
| | | | | | | We could almost use a multiclass for the signed/unsigned instructions, but there are only 6 of them so I guess it's not worth it. llvm-svn: 96297

* It turns out that we emitted completely wrong common EH frame since the ↵Anton Korobeynikov2010-02-151-7/+9
| | | | | | early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong. llvm-svn: 96287

* Split SelectionDAGISel::IsLegalAndProfitableToFold toEvan Cheng2010-02-158-39/+63
| | | | | | | | IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use. This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses. llvm-svn: 96255
