62b5a4d14c Revert 122959, it needs more thought. Add it back to README.txt with additional notes.

fb2bb22b6f InstCombine: Turn _chk functions into the "unsafe" variant if length and max langth are equal. 
This happens when we take the (non-constant) length from a malloc.

5834b2bab8 InstCombine: If we call llvm.objectsize on a malloc call we can replace it with the size passed to malloc.

6b38179ee2 Verify function prototypes before trying to optimize functions. We also 
need TargetData, just return false if we don't have it.

Update testcases accordingly.

Fixes PR6807.

484bbe6aa9 Reapply address space patch after fixing an issue in MemCopyOptimizer. 
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

a671e4f7aa Migrate _chk call lowering from SimplifyLibCalls to InstCombine. Stub 
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.

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

Modified:
   llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp
   llvm/trunk/test/Transforms/InstCombine/objsize.ll

It appears to be causing swb and nightly test failures.

d9816ef946 Instcombine constant folding can normalize gep with negative index to index with large offset. When instcombine objsize checking transformation sees these geps where the offset seemingly point out of bound, it should just return "i don't know" rather than asserting.

96f3c4222f Fix a problem where we had bitcasted operands that gave us 
odd offsets since the bitcasted pointer size and the offset pointer
size are going to be different types for the GEP vs base object.

symbols.

428b385575 Add a new pass to do llvm.objsize lowering using SCEV. 
Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase
to new directory.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

9b3e42f09e Rework constant expr and array handling for objectsize instcombining. 
Fix bugs where we would compute out of bounds as in bounds, and where
we couldn't know that the linker could override the size of an array.

Add a few new testcases, change existing testcase to use a private
global array instead of extern.

particular size, we just don't know what the length is yet.

SelectionDAGBuild.
