* Switch <elf.h> over to linux uapi under the covers.Elliott Hughes2014-02-101-4/+4
| | | | | | | | | | | | Remove the linker's reliance on BSD cruft and use the glibc-style ElfW macro. (Other code too, but the linker contains the majority of the code that needs to work for Elf32 and Elf64.) All platforms need dl_iterate_phdr_static, so it doesn't make sense to have that part of the per-architecture configuration. Bug: 12476126 Change-Id: I1d7f918f1303a392794a6cd8b3512ff56bd6e487
* Fix x86_64 build, clean up intermediate libraries.Elliott Hughes2013-10-091-2/+3
| | | | | | | | | | | | | | | | | | | | | | The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

* Remove 32-bit assumptions from the ELF code.Elliott Hughes2013-09-301-4/+4

* Switch to using AT_RANDOM for the stack guards.Elliott Hughes2013-02-081-2/+1

* Clean up the argc/argv/envp/auxv handling.Elliott Hughes2013-02-071-0/+111
There's now only one place where we deal with this stuff, it only needs to be parsed once by the dynamic linker (rather than by each recipient), and it's now easier for us to get hold of auxv data early on. Change-Id: I6314224257c736547aac2e2a650e66f2ea53bef5
