llvm-svn: 177563
 2013-03-20 19:25:58 +00:00
Michael J. Spencer 602ffc13b8 [ELF][Reader] Refactor how relocations are read. Improves performance. 
This changes from reading each relocation individually for each section to just
storing the range of relocations. It also counts the relocations to preallocate
the _references array.

This is the standard way of implementing LLVM RTTI.

llvm-svn: 177555
 2013-03-20 18:57:27 +00:00
Michael J. Spencer 6580d1f226 Set ordinals correctly. 
This actually doesn't change behavior with the current LinkerInvocation, but
it's needed when you make reading parallel.

Michael J. Spencer 3e00c5015f [ELF][x86-64] Only emit a PLT entry for a PLT relocation if the target atom is a SharedLibraryAtom. 
This seems to be what ld does, but I'm not sure how it works with symbol interposition.

With this hello-world with glibc dynamically linked works.
