Cameron Zwarich [Wed, 16 Mar 2011 22:20:18 +0000 (22:20 +0000)]
The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byte
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not
generate incorrect code.

This just fixes the zext at the return. We still insert an i32 ZextAssert when
reading a function's arguments, but it is followed by a truncate and another i8
ZextAssert so it is not optimized.

Add C++ global operator {new,new[],delete,delete[]}(unsigned {int,long}) to the
memory builtins as equivalent to malloc/free.

This is different from any attribute we have. For example, you can delete the
allocators when their result is unused, but you can't collapse two calls to the
same function, even if no global/memory state has changed in between. The
noalias return states that the result does not alias any other pointer, but
instcombine optimizes malloc() as though the result is non-null for the purpose
of eliminating unused pointers.

is represented by getelementptr with two uses (load and store) and
