Don't use operator[] here, because it's not desirable to insert a default
value if the search fails.

Remove an unused variable. The call to getRoot has side-effects, so
this could break something (but doesn't seem to).

Remove initialized but otherwise unused variables.

The hasMemory argument is irrelevant to how the argument
for an "i" constraint should get lowered; PR 6309. While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

Remove variables which are assigned to but for which the value
is not used. Spotted by gcc-4.6.

Simplify this code; switch lowering shouldn't produce cases
which trivially fold away.

llvm-svn: 106765

Optimize the "bit test" code path for switch lowering in the
case where the bit mask has exactly one bit.

Revert r106422, which is breaking the non-fast-isel path.

More changes for non-top-down fast-isel.

Split the code for materializing a value out of
SelectionDAGBuilder::getValue into a helper function, so that it can
be used in other ways. Add a new getNonR

More changes for non-top-down fast-isel.

Split the code for materializing a value out of
SelectionDAGBuilder::getValue into a helper function, so that it can
be used in other ways. Add a new getNonRegisterValue function which
uses it, for use in code which doesn't want a CopyFromReg even
when FuncMap.ValueMap already has an entry for it.

Eliminate unnecessary uses of getZExtValue().

Keep track of incoming debug value of unused argument.

Reorder some code in SelectionDAGBuilder.

SelectionDAG shouldn't have a FunctionLoweringInfo member. RegsForValue
shouldn't have a TargetLoweringInfo member. And FunctionLoweringInfo::set
doesn't needs its EnableFastISel argument.

Eliminate the restriction that the array size in an alloca must be i32.
This will help reduce the amount of casting required on 64-bit targets.

back out 104862/104869. Can reuse stacksave after all. Very cool.

hook ISD::STACKADDR to an intrinsic

Adjust eh.sjlj.setjmp to properly have a chain and to have an opcode entry in
ISD::. No functional change.

llvm-svn: 104734

Implement eh.sjlj.longjmp for ARM. Clean up the intrinsic a bit.
Followups: docs patch for the builtin and eh.sjlj.setjmp cleanup to match
longjmp.

I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename it
to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is
the opposite, for future use by dragonegg.

Use getValue() for PHINodes when direct NodeMap access does not work.
