| | | | llvm-svn: 118939
* Eliminate ARM::MOVi2pieces. Just use MOVi32imm and expand it to either ↵Evan Cheng2010-11-125-72/+34
| | | | | | movi+orr or movw+movt depending on the subtarget. llvm-svn: 118938
* Make this happen for ARM like x86. Don't entirely bail out whenEric Christopher2010-11-121-4/+5
| | | | | | | an address is in a different block, get it into a register and go from there. llvm-svn: 118936
* Add conditional mvn instructions.Evan Cheng2010-11-123-10/+67
| | | | llvm-svn: 118935
* Zap a copy/paste-o bit of dead code.Jim Grosbach2010-11-121-2/+0
| | | | llvm-svn: 118926
* Refactor to parameterize some ARM load/store encoding patterns. PreparatoryJim Grosbach2010-11-122-86/+24
| | | | | | | to splitting the load/store pre/post indexed instructions into [r, r] and [r, imm] forms. llvm-svn: 118925
* First stab at providing correct Thumb2 encodings, start with adc.Owen Anderson2010-11-123-19/+122
| | | | llvm-svn: 118924
* Have GVN simplify instructions as it goes. For example, considerDuncan Sands2010-11-121-18/+20
| | | | | | | | | | | | | | | "%z = %x and %y". If GVN can prove that %y equals %x, then it turns this into "%z = %x and %x". With the new code, %z will be replaced with %x everywhere (and then deleted). Previously %z would be value numbered too, which is a waste of time. Also, while a clever value numbering algorithm would give %z the same value number as %x, our current one doesn't do so (at least I don't think it does). The new logic has an essentially equivalent effect to what you would get if %z was given the same value number as %x, i.e. it should make value numbering smarter. While there, get hold of target data once at the start rather than a gazillion times all over the place. llvm-svn: 118923
* Add some missing isel predicates on def : pat patterns to avoid generating ↵Evan Cheng2010-11-123-64/+54
| | | | | | VFP vmla / vmls (they cause stalls). Disabling them in isel is properly not a right solution, I'll look into a proper solution next. llvm-svn: 118922
* Kill more unused stuff.Jim Grosbach2010-11-121-43/+0
| | | | llvm-svn: 118921
* MCELF: Copy the symbol name only if we're going to modify it.Benjamin Kramer2010-11-121-9/+8
| | | | llvm-svn: 118920
* Remove unused class.Jim Grosbach2010-11-121-8/+0
| | | | llvm-svn: 118919
* When the definition of an address value is in a different blockDan Gohman2010-11-121-5/+5
| | | | | | | | from the user of the address, fall back to just using the address in a register instead of bailing out of fast-isel altogether. llvm-svn: 118917
* accept lret as an alias for lretl, fixing the reopened part of PR8592Chris Lattner2010-11-122-2/+5
| | | | llvm-svn: 118916
* Remove what looks like dead code in the production of debug lines.Rafael Espindola2010-11-121-45/+2
| | | | | | | | | We only produce debug line information if we have seen a line directive, so this code is dead. Also, if we want to be bug by bug compatible with gas and sometimes produce "empty" .debug_line sections, this will match the content produced by gas. llvm-svn: 118914
* typo (4th checkin for one fix)Andrew Trick2010-11-121-1/+1

* Encoding for ARM LDRSB instructions.Jim Grosbach2010-11-121-7/+12
| | | | llvm-svn: 118905
* Fixes PR8287: SD scheduling time. The fix is a failsafe that preventsAndrew Trick2010-11-121-13/+53
| | | | | | | | | catastrophic compilation time in the event of unreasonable LLVM IR. Code quality is a separate issue--someone upstream needs to do a better job of reducing to llvm.memcpy. If the situation can be reproduced with any supported frontend, then it will be a separate bug. llvm-svn: 118904
* implement PR8592: empirically "lretq" is a "lret" with a rex.w prefix.Chris Lattner2010-11-121-0/+2
| | | | llvm-svn: 118903
* tidy up.Chris Lattner2010-11-122-10/+7

* gnu as support both % and @ before types, do the same.Rafael Espindola2010-11-121-10/+4
| | | | llvm-svn: 118893
* Re-disable TBAA for now; it broke MultiSource/Applications/JM/lencod,Dan Gohman2010-11-121-1/+1
| | | | | | at least. llvm-svn: 118890
* Fix memory access lowering on SPU, addingKalle Raiskila2010-11-124-115/+252
| | | | | | | | | | | | support for the case where alignment<value size. These cases were silently miscompiled before this patch. Now they are overly verbose -especially storing is- and any front-end should still avoid misaligned memory accesses as much as possible. The bit juggling algorithm added here probably has some room for improvement still. llvm-svn: 118889
