[lld][LayoutPass] This commit fixes a problem in the Layoutpass by ordering atoms if they appear in the override list first and then looking at the way of ordering atoms in the default way. The fix also fixes issues with the sizes of the sections, that appear in the output properly too. The commit also adds a testcase(orderatoms-by-override.test) to test it and fixes all the other relevant testcases. llvm-svn: 181605

# This test checks that IRELATIVE relocations are created for symbols that
# need relocation even for static links.
[lld][LinkingContext][ELF] Allow different output file types. This adds an option --output-filetype that can be set to either YAML/Native(case insensitive). The linker would create the outputs associated with the type specified by the user. Changes all the tests to use the new option. llvm-svn: 191183

This is my Driver refactoring patch. The major changes are: 1) LinkerOptions has been merged into TargetInfo 2) LinkerInvocation has been merged into Driver 3) Drivers no longer convert arguments into an intermediate (core) argument list, but instead create a TargetInfo object and call setter methods on it. This is only how in-process linking would work. That is, you can programmatically set up a TargetInfo object which controls the linking. 4) Lots of tweaks to test suite to work with driver changes 5) Add the DarwinDriver 6) I heavily doxygen commented TargetInfo.h Things to do after this patch is committed: a) Consider renaming TargetInfo, given its new roll. b) Consider pulling the list of input files out of TargetInfo. This will enable in-process clients to create one TargetInfo the re-use it with different input file lists. c) Work out a way for Drivers to format the warnings and error done in core linking. llvm-svn: 178776

[ELF][x86-64] Fix ifunc and add test. In an previous commit I managed to completely disable the IRELATIVE relocation writing code. I also used the wrong addend for the static relocation. Fix both these issues and add a test. This test is quite brittle because there's no way to do arithmetic on variables in FileCheck. llvm-svn: 174161
