Kevin Enderby 818b6b96cb Fixed MCSectionMachO::ParseSectionSpecifier to allow an attribute of "none" so 
that a symbol stub section with no attributes can be parsed as in:
.section __TEXT,__picsymbolstub4,symbol_stubs,none,16

Owen Anderson de1cb40eb4 Remove LazyLiveness from the tree. It doesn't work right now, and I'm not going to have the time 
to finish it any time soon.  If someone's interested it, they can resurrect it from SVN history.

Kevin Enderby 2207e5fc7b Add another bit of the ARM target assembler to llvm-mc to parse registers 
with writeback, things like "sp!", etc.  Also added some more stuff to the
temporarily hacked methods ARMAsmParser::MatchRegisterName and
ARMAsmParser::MatchInstruction to allow more parser testing.

 2009-10-07 18:01:35 +00:00
Dan Gohman 9b60992120 Replace some code for aggressive-remat with MachineInstr::isInvariantLoad, and 
teach it how to recognize invariant physical registers.

llvm-svn: 83476
 2009-10-07 17:47:20 +00:00
Dan Gohman be8137b0b4 Replace TargetInstrInfo::isInvariantLoad and its target-specific 
implementations with a new MachineInstr::isInvariantLoad, which uses
MachineMemOperands and is target-independent. This brings MachineLICM
and other functionality to targets which previously lacked an
isInvariantLoad implementation.

llvm-svn: 83475
 2009-10-07 17:38:06 +00:00
Dan Gohman db9493ce68 Add a few simple MachineVerifier checks for MachineMemOperands.

Bob Wilson 99e80228a9 Rearrange code for selecting vld2 intrinsics. No functionality change. 
This is just to be more consistent with the forthcoming code for vld3/4.

Jim Grosbach fa14dd430c Add register-reuse to frame-index register scavenging. When a target uses 
a virtual register to eliminate a frame index, it can return that register
and the constant stored there to PEI to track. When scavenging to allocate
for those registers, PEI then tracks the last-used register and value, and
if it is still available and matches the value for the next index, reuses
the existing value rather and removes the re-materialization instructions.
Fancier tracking and adjustment of scavenger allocations to keep more
values live for longer is possible, but not yet implemented and would likely
be better done via a different, less special-purpose, approach to the
problem.

eliminateFrameIndex() is modified so the target implementations can return
the registers they wish to be tracked for reuse.

ARM Thumb1 implements and utilizes the new mechanism. All other targets are
simply modified to adjust for the changed eliminateFrameIndex() prototype.

Torok Edwin 822f634d29 Add a comment explaining how DenseMap::insert works, because it is not 
intuitive.
It does NOT update the value if the key is already in the map,
it also returns false if the key is already in the map, regardless
if the value matched.

Torok Edwin a4560bad97 Add PR to this FIXME, looks like I didn't commit this change after all.

Duncan Sands 986742a14f Make getPointerTo return a const PointerType* rather than 
an unqualified PointerType* because it seems more correct.

Dan Gohman 2a685bdbee INTRINSIC_W_CHAIN and INTRINSIC_VOID do not use MemSDNode. They 
may access memory, but they don't carry a MachineMemOperand.

Eric Christopher e666bc9f64 Add FreeInst to the "is a call" check for Insts that are calls, but 
not intrinsics.

Dan Gohman f8e4410994 Fix this comment. The loop header is the loop entry point.

Anton Korobeynikov 75b59fb055 Add PseudoSourceValues for constpool stuff on ELF (Darwin should use something similar) 
and register spills.

llvm-svn: 83435
 2009-10-07 00:06:35 +00:00
Eric Christopher 6ba26317ce While we still have a MallocInst treat it as a call like any other 
for inlining.

When MallocInst goes away this code will be subsumed as part of
calls and work just fine...

Kevin Enderby febe39b488 Added bits of the ARM target assembler to llvm-mc to parse some load instruction 
operands.  Some parsing of arm memory operands for preindexing and postindexing
forms including with register controled shifts.  This is a work in progress.

Jeffrey Yasskin e2595b5be6 r83391 was completely broken since Twines keep references to their inputs, and 
some of the inputs were temporaries.  Here's a real fix for the miscompilation.
Thanks to sabre for pointing out the problem.

 2009-10-06 21:45:26 +00:00
Bob Wilson 3251776d1d Update NEON struct names to match llvm-gcc changes. 
(This is not required for correctness but might help with sanity.)

Nicolas Geoffray 08506ee6b0 Bugfix for the CommaSeparated option. The original code was adding the whole 
string at the end of the list, instead of the last comma-separated string.

This is not yet enabled.

Dan Gohman e66abdc58f Make LLVMContext's pImpl member const. 
llvm-svn: 83393
 2009-10-06 17:43:57 +00:00
Dan Gohman 10d3dc569b Instead of printing unnecessary basic block labels as labels in 
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.
