* clang doesn't propagate attributes like "asm labels" and "visibility(hidden)"guenther2017-11-291-2/+2
| | | | | | | | | to builtins like mem{set,cpy,move} and __stack_smash_handler. So, when building with clang, instead mark those as protected visibility to get rid of the PLT relocations. We can't take the address of them then, but that's ok: it's a build-time error not a run-time error. ok kettenis@
* Use internal names for __errno, _memcpy, memset, and {,_}{set,long}jmpguenther2016-08-061-2/+2

* Add framework for resolving (pun intended) libc namespace issues, usingguenther2015-08-311-2/+3
| | | | | | | | | | | | wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@
* At some point arm moved to a unified syntax for arm and thumb instructions.jsg2015-06-081-6/+8
| | | | | | | | | While binutils supports both "unified" and "divided" syntax (defaulting to divided) the integrated assembler in clang only supports unified names so switch some files to unified syntax. Similiar changes were made in bitrig and freebsd. No difference in objdump -d output. tested on zaurus by deraadt@, ok miod@
