Chris Lattner fd27f8a5b3 generalize a transformation even more: we don't care whether the
input the the mul is a zext from bool, just that it is all zeros
other than the low bit.  This fixes some phase ordering issues
that would cause us to miss some xforms in mul.ll when the worklist
is visited differently.

llvm-svn: 83791
2009-10-11 21:05:34 +00:00
Chris Lattner bb058d3a23 populate instcombine's initial worklist more carefully, causing
it to visit instructions from the start of the function to the
end of the function in the first path.  This greatly speeds up
some pathological cases (e.g. PR5150).

Torok Edwin 907ec36943 LICM shouldn't sink/delete debug information. Fix this and add a testcase.
For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

Chris Lattner 97b1405207 implement a transformation in jump threading that is currently
done by condprop, but do it in a much more general form.  The
basic idea is that we can do a limited form of tail duplication
in the case when we have a branch on a phi.  Moving the branch
up in to the predecessor block makes instruction selection
much easier and encourages chained jump threadings.

Chris Lattner b6c65faa64 switch GVN to use SSAUpdater. Besides removing a lot of complexity
from GVN, this also speeds it up, inserts fewer PHI nodes (see the
testcase) and allows it to remove more loads (due to fewer PHI nodes
standing in the way).

2009-10-10 09:09:20 +00:00
Chris Lattner 84095071ea Change jump threading to use the new SSAUpdater class instead of
DemoteRegToStack.  This makes it more efficient (because it isn't
creating a ton of load/stores that are eventually removed by a later
mem2reg), and more slightly more effective (because those load/stores
don't get in the way of threading).

llvm-svn: 83706
2009-10-10 09:05:58 +00:00

Chris Lattner 71db463fcf add some WeakVH::operator='s. Without these, assigning

Dan Gohman b8120770b4 Create a new InstrEmitter class for translating SelectionDAG nodes

Dan Gohman 4a72f7ab53 Mark the LDR instruction with isReMaterializable, as it is rematerializable
when loading from an invariant memory location.

llvm-svn: 83688
2009-10-09 23:28:27 +00:00
Dan Gohman 87b02d5bbc Factor out LiveIntervalAnalysis' code to determine whether an instruction
is trivially rematerializable and integrate it into
TargetInstrInfo::isTriviallyReMaterializable. This way, all places that
need to know whether an instruction is rematerializable will get the
same answer.

This enables the useful parts of the aggressive-remat option by
default -- using AliasAnalysis to determine whether a memory location
is invariant, and removes the questionable parts -- rematting operations
with virtual register inputs that may not be live everywhere.

Devang Patel df45c7f642 Extract scope information from the variable itself, instead of relying on alloca or llvm.dbg.declare location.

Jeffrey Yasskin 307c053f2e ExecutionEngine::clearGlobalMappingsFromModule failed to remove reverse

Kevin Enderby a2b99107c4 Added another bit of the ARM target assembler to llvm-mc to parse register
lists.  Changed ARMAsmParser::MatchRegisterName to return -1 instead of 0 on
errors so 0-15 values could be returned as register numbers.  Also added the
rest of the arm register names to the currently hacked up version to allow more
testing.  Some changes to ARMAsmParser::ParseOperand to give different errors
for things not yet supported and some additions to the hacked
ARMAsmParser::MatchInstruction to allow more testing for now.

Dan Gohman 7d9dffb413 Fix the x86 test-shrink optimization so that it doesn't shrink comparisons

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.

where the element is of a basic builtin type.  For example, to get
an i8* use getInt8PtrTy.

Jim Grosbach 2dfb5da6bb In Thumb1, the register scavenger is not always able to use an emergency
spill slot. When frame references are via the frame pointer, they will be
negative, but Thumb1 load/store instructions only allow positive immediate
offsets. Instead, Thumb1 will spill to R12.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.
