* Speed up AddSectionToTheEnd. It was walking all fragments in all sections.Rafael Espindola2010-11-071-19/+4
| | | | | | | | | | This is really slow with we have 1000s of sections each with a corresponding relocation section. Also, it is only used by the ELF writer to add basic data, so there is no need to force a new layout pass. Should fix PR8563. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118377 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for files with more than 65280 sections. No testcase sinceRafael Espindola2010-10-311-42/+109
| | | | | | it would be a bit too big :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117849 91177308-0d34-0410-b5e6-96231b3b80d8
* Be more strict on when we produce an undefined reference. In gas a file withRafael Espindola2010-10-291-1/+4
| | | | | | | | | | | | | | | | | | | | | | | just .type foo,@object will produce an undefined reference to foo. On the other hand, a file with just .weakref bar, foo will not. It is somewhat hard to support both in MC since both statements should create the symbols. It should be possible if we really need to by adding to the flags, but hopefully that is not necessary. With this patch we do not produce a undefined reference in any of those cases. The assembly file needs an actual use for the undefined reference to be present. This is in preparation for a patch implementing .weakref. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117735 91177308-0d34-0410-b5e6-96231b3b80d8
