|\ | | | | | | | | | | | | libraries." * commit '8826ba8ab6922927bdac2466d2903916d5806a06': Fix x86_64 build, clean up intermediate libraries.
| * Fix x86_64 build, clean up intermediate libraries.Elliott Hughes2013-10-093-3/+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.

| * Change how DNS resolver handle no default ifaceRobert Greenwalt2013-08-221-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to just try any iface we'd been told about as a fallback, but that will end up mistakenly using a secondary network's dns when we really don't have a default connection. It also messed up our detection of whether we were doing the lookup on the default or not (we'd get back our secondary net iface as the default, do the compare and think we were on default). Remove the lies and let dns fail if we don't have an iface for it. bug:10132565 Change-Id: I5f0f2abacaaaaf23c5292b20fba9d8dcb6fb10c5

| | * bionic: move system property writing from init to bionicColin Cross2013-06-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the implementation of writing to the system property area from init to bionic, next to the reader implementation. This will allow full property testing to be added to bionic tests. Add new accessor and waiting functions to hide the implementation from watchprops and various bionic users. Also hide some of the implementation details of the property area from init by moving them into _system_properties.h, and other details from everybody by moving them into system_properties.h.
