llvm/test/ExecutionEngine/test-loadstore.ll
Preston Gurd c68dda815e This patch improves the MCJIT runtime dynamic loader by adding new handling
of zero-initialized sections, virtual sections and common symbols
and preventing the loading of sections which are not required for
execution such as debug information.

Patch by Andy Kaylor!
