* On ELF we need to know which symbols are used in relocations to decide ifRafael Espindola2010-10-051-51/+0
| | | | | | | they should be in the symbol table or not. Instead of "guessing", just compute the symbol table after the relocations are known. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115619 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a InitSections method to the streamer interface.Rafael Espindola2010-09-151-0/+33
| | | | | | | | | | | | | | The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114027 91177308-0d34-0410-b5e6-96231b3b80d8
* Factoring and potential bug fix. The elf "flags" cannot be used as masks.Rafael Espindola2010-09-131-14/+37
| | | | | | | For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce a STT_SECTION (3). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113759 91177308-0d34-0410-b5e6-96231b3b80d8
