Change how we iterate over relocations on ELF. For COFF and MachO, sections semantically have relocations that apply to them. That is not the case on ELF. In relocatable objects (.o), a section with relocations in ELF has offsets to another section where the relocations should be applied. In dynamic objects and executables, relocations don't have an offset, they have a virtual address. The section sh_info may or may not point to another section, but that is not actually used for resolving the relocations. This patch exposes that in the ObjectFile API. It has the following advantages: * Most (all?) clients can handle this more efficiently. They will normally walk all relocations, so doing an effort to iterate in a particular order doesn't save time. * llvm-readobj now prints relocations in the same way the native readelf does. * probably most important, relocations that don't point to any section are now visible. This is the case of relocations in the rela.dyn section. See the updated relocation-executable.test for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182908 91177308-0d34-0410-b5e6-96231b3b80d8

Enable EHABI by default After all hard work to implement the EHABI and with the test-suite passing, it's time to turn it on by default and allow users to disable it as a work-around while we fix the eventual bugs that show up. This commit also remove the -arm-enable-ehabi-descriptors, since we want the tables to be printed every time the EHABI is turned on for non-Darwin ARM targets. Although MCJIT EHABI is not working yet (needs linking with the right libraries), this commit also fixes some relocations on MCJIT regarding the EH tables/lib calls, and update some tests to avoid using EH tables when none are needed. The EH tests in the test-suite that were previously disabled on ARM now pass with these changes, so a follow-up commit on the test-suite will re-enable them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200388 91177308-0d34-0410-b5e6-96231b3b80d8
