* Fix __errno for LP64 and clean up __get_tls.Elliott Hughes2013-10-0913-102/+55
| | | | | | | | | | | If __get_tls has the right type, a lot of confusing casting can disappear. It was probably a mistake that __get_tls was exposed as a function for mips and x86 (but not arm), so let's (a) ensure that the __get_tls function always matches the macro, (b) that we have the function for arm too, and (c) that we don't have the function for any 64-bit architecture.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In c++11, register has been deprecated, and libc is now built as gnu++11 From the documentation: A register specifier is a hint to the implementation that the variable so declared will be heavily used. [ Note: The hint can be ignored and in most implementations it will be ignored if the address of the variable is taken.

(I was confused when I suggested otherwise.) I've also cleaned up the internal_types.h situation; we weren't gaining anything from these empty files, and there is no upstream internal_types.h for x86_64.

| | | | | | | | | | | | | | | | | | | | | | The NDK ABI requires that you support SSE2, and the build system won't let you build with ARCH_X86_HAVE_SSE2 set to false. So let's stop pretending this constant is actually a variable, and let's remove the corresponding dead code. Also, the USE_SSE2 and USE_SSE3 macros are unused, so let's not bother setting them.
