This is a first step towards eliminating unncessary constructor checks in light weight DIDescriptor wrappers.

Patch by John Tytgat!

llvm-svn: 97886

We cannot use a normal call here since it has extra unmodelled side
effects (it changes stack pointer). This should fix PR5292.

llvm-svn: 97884

llvm-svn: 97883

Do not use '&' prefix for globals when register base field is non-zero, otherwise msp430-as will silently miscompile the code (TI's assembler report an error though).

This fixes PR6349

before we try to optimize.

llvm-svn: 97876

out the remainder of the calls that we should lower in some way and
move the tests to the new correct directory. Fix up tests that are now
optimized more than they were before by -instcombine.

registers may be restored via a pop instruction, not just a tRestore.
This fixes nightly test 471.omnetep for Thumb1.

Log:
Transform @llvm.objectsize to integer if the argument is a result of malloc of known size.

Modified:

It appears to be causing swb and nightly test failures.

is a workaround for <rdar://problem/7672401/> (which I filed).

This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

can be used in more places.  Add an argument for the TargetData that
most of them need. Update for the getInt8PtrTy() change.  Should be
no functionality change.

   CALL ... %RAX<imp-def>
   ... [not using %RAX]
   %EAX = ..., %RAX<imp-use, kill>
   RET %EAX<imp-use,kill>

Now we do this:

   CALL ... %RAX<imp-def, dead>
   ... [not using %RAX]
   %EAX = ...
   RET %EAX<imp-use,kill>

By not artificially keeping %RAX alive, we lower register pressure a bit.

The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously
55, anybody can see that. Sheesh.
