[ARM] Add Virtualization subtarget feature and more build attributes in this area Add a Virtualization ARM subtarget feature along with adding proper build attribute emission for Tag_Virtualization_use (encodes Virtualization and TrustZone) and Tag_MPextension_use. Also rework test/CodeGen/ARM/2010-10-19-mc-elf-objheader.ll testcase to something that is more maintainable. This changes the focus of this testcase away from testing CPU defaults (which is tested elsewhere), onto specifically testing that attributes are encoded correctly. llvm-svn: 193859

[llvm-readobj] Update tests because of changes in llvm-readobj behavior This patch updates tests using llvm-readobj and llvm-readelf, because soon reading from stdin will be achievable only via a '-' as described here: https://bugs.llvm.org/show_bug.cgi?id=46400. Patch with changes to llvm-readobj behavior is here: https://reviews.llvm.org/D83704 Differential Revision: https://reviews.llvm.org/D83912 Reviewed by: jhenderson, MaskRay, grimar

Stop uppercasing build attribute data. The string data for string-valued build attributes were being unconditionally uppercased. There is no mention in the ARM ABI addenda about case conventions, so it's technically implementation defined as to whether the data are capitialised in some way or not. However, there are good reasons not to captialise the data. * It's less work. * Some vendors may legitimately have case-sensitive checks for these attributes which would fail on LLVM generated object files. * There could be locale issues with uppercasing. The original reasons for uppercasing appear to have stemmed from an old codesourcery toolchain behaviour, see http://comments.gmane.org/gmane.comp.compilers.llvm.cvs/87133 This patch makes the object file emitted no longer captialise string data, it encodes as seen in the assembly source.
