Extended Description

The strcopy and optimizations are not used when there's no platform data (espeacially the alignment information).

There are two ways to fix that:
a) an additional parameter to opt or llvm-ld that auto-injects the platform data or use the native platform
b) a command line tool that outputs the recommendend alignment settings on each platform to get the best speed

thanks for implementing ;)

This is a feature, which allows you to perform target independent optimizations on target independent bytecode files without making them magically target specific. If you want these optimizations, your frontend should introduce a target data string.
