Implementations

`impl TargetDataLayout`[src]

`pub fn parse(target: &Target) -> Result<TargetDataLayout, String>`[src]

`pub fn obj_size_bound(&self) -> u64`[src]

Returns exclusive upper bound on object size.

The theoretical maximum object size is defined as the maximum positive isize value. This ensures that the offset semantics remain well-defined by allowing it to correctly index every address within an object along with one byte past the end, along with allowing isize to store the difference between any two pointers into an object.

The upper bound on 64-bit currently needs to be lower because LLVM uses a 64-bit integer to represent object size in bits. It would need to be 1 << 61 to account for this, but is currently conservatively bounded to 1 << 47 as that is enough to cover the current usable address space on 64-bit ARMv8 and x86_64.
