Michael J. Spencer 8c0526593a [Writer][ELF][x86-64] Handle GOTPCREL relocations to SharedLibraryAtoms. 
llvm-svn: 176324
 2013-03-01 01:09:46 +00:00
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.

Michael J. Spencer 7f09a3d54e [Pass][Layout] Fix bug and add debug printing. 
Fix a bug where if two atoms had the same index in the override map,
the compare would return false. It now goes to the next check when
they are equal.

No test because it currently can't be tested. An upcomming patch will test it.

Chandler Carruth 21aaf2534d Switch a vector<pair<const T &, const U &>> to a vector<pair<const T *, 
const U *>>. Even in C++11 it doesn't seem this is valid as vector's
emplace support requires move assignment, and there is no way to move
assign a reference.

The real motivation however is that this fixes the build of lld with
libstdc++ 4.6.

Michael J. Spencer be03e2a861 [Core,Driver,ELF] Differentiate static and dynamic executables.

x86-64 ELF.

Michael J. Spencer db18847b01 [ELF][Writer] Refactor Section to not have atoms. Move atoms into AtomSection. 
The purpose of this change is to simplify creating non-atom sections.
Previously _contentType, _sectionKind and _order were used for multiple
purposes and collided in places. This moves all of the Atom specific logic down
into AtomSection and makes Section just have raw Elf_Shdr flags.
