[PATCH] D46896: [llvm-objcopy] Add --strip-unneeded option

[James Henderson via Phabricator via llvm-commits]

jhenderson added a comment.

I'm now getting a bit lost. Please could you outline the GNU objcopy behaviour for the following axes:

Axis 1: elf type (ET_REL versus ET_DYN/ET_EXEC)
Axis 2: symbol binding (Global/Weak/Local)
Axis 3: undefined/defined symbols

This should help us evaluate the behaviour and determine if the approach taken is correct. It should be straightforward to generate these different cases using yaml2obj, like you do in the tests.
