Rafael Espindola c2d211994d Create the .bss section early so that we don't have to set it after the fact.

 2015-09-22 23:38:23 +00:00
Rafael Espindola 7f07442bb6 Move the last remaining hard coded relocations to Target. 
Unfortunately the i386 and x86_64 relocation have the same numerical value
and it is a probably a bit much to add got support for another architecture
just to test this.

Rafael Espindola 01205f79a4 Start adding target abstractions. 
This is just enough to get PLT working on 32 bit x86.

The idea behind using a virtual interface is that it should be easy to
convert any of the functions to template parameters if any turns out to be
performance critical.

 2015-09-22 18:19:46 +00:00
Rafael Espindola 50534c2b6f Fix the creation of Elf_Rel sections. 
We were always incrementing the output buffer pointer by sizeof(Elf_Rela).

 2015-09-22 17:49:38 +00:00
Rafael Espindola 454ca1c245 Use a signed value for Delta. 
This fixes got.s on 32 bit windows.

Patch by Igor Kudrin!

llvm-svn: 248218
 2015-09-21 22:14:55 +00:00
Rafael Espindola 4ea00210f2 Make InputSection able to relocate itself. 
This matches the organization used in COFF.

llvm-svn: 248215
 2015-09-21 22:01:00 +00:00
Rafael Espindola 5805c4f509 Move OutputSectionBase and derived classes out of Writer.cpp. 
The file was getting a bit too big and OutputSection is a central enough
concept in ELF linking to justify its own file.
