so we can destroy it even if it was constructed with "DelayInitialization = true",
and we didn't end up calling Preprocessor::Initialize.

Apart from being slightly cheaper, this fixes a real bug that hits 32 bit
linux systems. When passing a file larger than 2G to be linked (which isn't
that uncommon with large projects such as WebKit), clang's driver checks
if the file exists but the file size doesn't fit in an off_t and stat(2)
fails with EOVERFLOW. Clang then says that the file doesn't exist instead
of passing it to the linker.

FYI, LLVM_ON_WIN32 is useless.

-mhard-float, and -mfloat-abi= to the new function getMipsFloatABI. That
simplifies reuse of this code.

- Fixed IntegersSubsetGeneric copy/assignment behaviour. 
- Fixed IntegersSubsetGeneric::getSize/getSingleValue methods.
- Fixed IntegersSubsetGeneric::verify method.

Also IntegersSubset.h and IntegersSubsetMapping.h headers was fixed.

Small fix due to buildbot failures on mingw32. Fixed call of parent constructor for case when parent is template.

IntegersSubsetGeneric, IntegersSubsetMapping: added IntTy template parameter, that allows use either APInt or IntItem. This change allows to write unittest for these classes.

This will make it easier to add inlining support to more expressions.

custom-lower unaligned load and store nodes.

This is the first of a series of patches which make changes to the backend to
emit unaligned load/store instructions (lwl,lwr,swl,swr) during instruction
selection.

the MachineOperand type has a valid offset. 

llvm-svn: 157861

When we timeout or exceed a max number of blocks within an inlined
function, we retry with no inlining starting from a node right before
the CallEnter node. We assume the state of that node is the state of the
program before we start evaluating the call. However, the node pruning
removes this node as unimportant. 

Teach the node pruning to keep the predecessors of the call enter nodes.

We should not stop exploring the path after we return from an empty
function.

Designate MachThreadList as a transaction coordinator when doing Enable/DisableHardwareWatchpoint on the list of threads.
In case the operation (iterating on the threads and doing enable/disable) fails in the middle, we rollback the already
enabled/disabled threads to their checkpointed states.  When all the threads succeed in enable/disable, we ask each thread
to finsih the transaction and commit the change of the debug state.

These functions exposed the layout of the underlying data tables as
null-terminated uint16_t arrays.

Use the new MCSubRegIterator, MCSuperRegIterator, and MCRegAliasIterator
classes instead.

No functional change intended.

Sorry for the churn. The iterator classes are supposed to help avoid
giant commits like this one in the future. The TableGen-produced
register lists are getting quite large, and it may be necessary to
change the table representation.

This makes it possible to do so without changing all clients (again).

inject some code in that will run via the "__mod_init_func" method that
registers the gcov "writeout" function to execute at exit time.

The problem is that the "__mod_term_func" method of specifying d'tors is
deprecated on Darwin. And it can lead to some ambiguities when dealing with
multiple libraries.
