* Fix filename in comment in cmathm4tx2014-09-141-1/+1
| | | | | | | It looks like the file comment was copy-pasted from ctime. Fixed filename in comment to "math.h". Change-Id: I27b0c2a7827076a91fc7b63913fad6eee4d6a79e Signed-off-by: m4tx <m4tx@m4tx.pl>

* Move libstdc++ into libc.Elliott Hughes2014-05-146-235/+3
| | | | | | | | | | | | | | | | | | | | The Android build system always links against libstdc++.so anyway. Having operator new and operator delete in a separate library means we can't use constructors and destructors on heap-allocated objects inside the C library, which is quite an unfortunate limitation. This will be cheaper too; on LP64 we can stop linking against the [now empty] libstdc++.so giving the dynamic linker one less library to worry about for every process. There's precedent too --- we already have no libpthread or librt. For now I'm leaving the include files where they are, and I'm generating a dummy libstdc++.so and libstdc++.a. We can come back and clean that up later if all goes well. Bug: 13367666 Change-Id: I6f3e27ea7c30d03d6394965d0400c9dc87fa83db

* 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.

* Clean up internal libc logging.Elliott Hughes2013-03-151-1/+1
| | | | | | | | | | | We only need one logging API, and I prefer the one that does no allocation and is thus safe to use in any context. Also use O_CLOEXEC when opening the /dev/log files. Move everything logging-related into one header file. Change-Id: Ic1e3ea8e9b910dc29df351bff6c0aa4db26fbb58
* Regenerate all NOTICE files with the latest version of the script.Elliott Hughes2012-08-151-25/+25

* Add dependencies on all the makefiles.Elliott Hughes2012-08-131-0/+2

* Auto-generate a complete NOTICE file.Elliott Hughes2012-08-092-25/+82

* Report errors to the log, not just stderr.Elliott Hughes2012-07-273-11/+9
| | | | | | | | | | In particular this affects assert(3) and __cxa_pure_virtual, both of which have managed to confuse people this week by apparently aborting without reason. (Because stderr goes nowhere, normally.) Bug: 6852995 Bug: 6840813 Change-Id: I7f5d17d5ddda439e217b7932096702dc013b9142

| * libstdc++: Fix x86 thread-safe one-time-construction implementation.Fengwei Yin2012-04-161-18/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The root of the problem is that the existing implementation is based on the ARM C++ ABI, which mandates a different guard variable layout than the Itanium/x86 C++ one. This patch modifies the implementation in a way that satisfies both ABIs (and doesn't require changing the toolchains).

* | bionic: Do not use <sys/atomics.h> for platform code.David 'Digit' Turner2011-11-161-3/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're going to modify the __atomic_xxx implementation to provide full memory barriers, to avoid problems for NDK machine code that link to these functions. First step is to remove their usage from our platform code. We now use inlined versions of the same functions for a slight performance boost. + remove obsolete atomics_x86.c (was never compiled) NOTE: This improvement was benchmarked on various devices. Comparing a pthread mutex lock + atomic increment + unlock we get: - ARMv7 emulator, running on a 2.4 GHz Xeon: before: 396 ns after: 288 ns - x86 emulator in KVM mode on same machine: before: 27 ns after: 27 ns - Google Nexus S, in ARMv7 mode (single-core): before: 82 ns after: 76 ns - Motorola Xoom, in ARMv7 mode (multi-core): before: 121 ns after: 120 ns The code has also been rebuilt in ARMv5TE mode for correctness.

* libstdc++: make operator new call abort on failure.David 'Digit' Turner2011-06-141-2/+2
| | | | | | | | | | | This change ensures that operator new will call abort() in case of memory allocation failure. Note that due to our usage of memory overcommit, this can only happen under very rare circumstances (i.e. trying to allocate memory larger than the larger free range of virtual address space, or when memory is corrutped in various ways).
