* Revert "Unregister pthread_atfork handlers on dlclose()"Dimitry Ivanov2015-04-242-259/+0
| | | | | | | | | The visibility control in pthread_atfork.h is incorrect. It breaks 64bit libc.so by hiding pthread_atfork. This reverts commit 6df122f8528f9b9fcf7dfea14ae98b0ef66274e1. Change-Id: I21e4b344d500c6f6de0ccb7420b916c4e233dd34

* Slim down static binaries by avoiding stdio.Elliott Hughes2014-07-101-3/+2
| | | | | | | | | | | | | | It's okay for a program to choose to drag in stdio, but it's unfortunate if even the minimal "int main() { return 42; }" drags in stdio... This brings the minimal static binary on ARM down from 78KiB to 46KiB. Given that we don't have a separate -lpthread it's not obvious to me that we can shave this down any further. I'm not sure whether this is a worthwhile change for that reason. (And the fact that dynamic binaries, the usual case, are unaffected either way.) Change-Id: I02f91dcff37d14354314a30b72fed2563f431c88

* Clean up localeconv(3).Elliott Hughes2014-04-081-4/+0
| | | | | | | The OpenBSD doesn't support C99, and the extent to which we support locales is trivial, so just do it ourselves. Change-Id: If0a06e627ecc593f7b8ea3e9389365782e49b00e

| | | | | | | | | | | | lconv is taken from ndk/sources/android/support/include/locale.h and matches bsd/glibc upstream. Keep old declaration for 32-bits for compatibility. localeconv.c and deps are taken from openbsd upstream. Changed strtod.c accordingly.

* Clean up reentrancy cruft.Elliott Hughes2014-03-131-20/+4
| | | | | | | | | | | | | | | | The DNS copy of reentrant.h was unused, so remove it. The strtod implementation can use the upstream-netbsd reentrant.h and get a little closer to what was then upstream. (It's since been replaced by gdtoa, and we'll have to follow at some point, but for now this doesn't make anything any worse.) ANDROID_CHANGES is (now) only used in the DNS code, so push the -D down. The <locale.h> change prevents an LP32 hack from leaking into LP64. Change-Id: Idf30b98a59d7ca8f7c6cd6d07020b512057911ef

* bionic: call stdio cleanup on exitPawit Pornkitprasan2013-11-191-59/+0
| | | | | | | | | | | | | | | As of 61e699a133a4807fe878a6cb0d7190d7c96e21f8, stdio clean up functions are no longer registered in atexit and must be called manually via __cleanup. The issue this fixes is some static binaries linked against bionic cannot output properly when piped or redirected because the buffer is not flushed before closing. This is done by pulling in exit.c (and other dependencies) from netbsd. Change-Id: I193e54a6d08900f291550029fe75ce76394d9e22

* Fix x86_64 build, clean up intermediate libraries.Elliott Hughes2013-10-093-2/+9
| | | | | | | | | | | | | | | | | | | | | | 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.

* Make ctype.h a little less unhygienic.Elliott Hughes2013-08-131-1/+11

* Clean up abort.Elliott Hughes2013-06-121-40/+2
| | | | | | | | | | | | | | | | | | * A dlmalloc usage error shouldn't call abort(3) because we want to cause a SIGSEGV by writing the address dlmalloc didn't like to an address the kernel won't like, so that debuggerd will dump the memory around the address that upset dlmalloc. * Switch to the simpler FreeBSD/NetBSD style of registering stdio cleanup. Hopefully this will let us simplify more of the stdio implementation. * Clear the stdio cleanup handler before we abort because of a dlmalloc corruption error. This fixes the reported bug, where we'd hang inside dlmalloc because the stdio cleanup reentered dlmalloc. Bug: 9301265 Change-Id: Ief31b389455d6876e5a68f0f5429567d37277dbc

* ARM: make CRT_LEGACY_WORKAROUND work as intendedArd Biesheuvel2012-08-281-11/+0
| | | | | | | | | | | | | To properly support legacy ARM shared libraries, libc.so needs to export the symbols __dso_handle and atexit, even though these are now supplied by the crt startup code. This patch reshuffles the existing CRT_LEGACY_WORKAROUND conditionally compiled code slightly so it works as the original author likely intended.
