# This tests the basic functionality of ordering data and functions as they
[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

[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

[lld][LayoutPass] Order the atoms that are in the same chain We need to order atoms that exist in the same chain. This is to make sure that the command line order is preserved when we emit the atoms to the output file. Credits: BigCheese for finding the bug.

ELF: Don't use LayoutPass. Previously we applied the LayoutPass to order atoms and then apply elf::ArrayOrderPass to sort them again. The first pass is basically supposed to sort atoms in the normal fashion (which is to sort symbols in the same order as the input files). The second pass sorts atoms in {init,fini}_array.<priority> by priority. The problem is that the LayoutPass is overkill. It analyzes references between atoms to make a decision how to sort them. It's slow, hard to understand, and above all, it doesn't seem that we need its feature for ELF in the first place. This patch remove the LayoutPass from ELF pass list. Now all reordering is done in elf::OrderPass. That pass sorts atoms by {init,fini}_array, and if they are not in the special section, they are ordered as the same order as they appear in the command line. The new code is far easier to understand, faster, and still able to create valid executables. Unlike the previous layout pass, elf::OrderPass doesn't count any attributes of an atom (e.g. permissions) except its position. It's OK because the writer takes care of them if we have to. This patch changes the order of final output, although that's benign. Tests are updated. http://reviews.llvm.org/D7278 llvm-svn: 227666
