66f7b2758f Merge "Remove unnecessary #undefs from AOSP." into lmp-mr1-dev-plus-aosp 2014-12-02 23:00:37 +00:00

6c1e3f6e56 Remove unnecessary #undefs from AOSP.
This is a manual revert of 111461aaaec2b7d9ffa5f3baabb1bd019d2e0c1d.
git revert does the wrong thing because that patch shares lines (that we
want to keep) with 168667c972a1e9ede5b64ad6cee0666e9b96d4d8 and git
revert just removes them.

432f645887 Fix flockfile(3) and friends for stdin/stdout/stderr too.
stdin/stdout/stderr are special; their mutexes are initialized by
__sinit. There's no unit test for this, because __sinit has already
been called by the time the first unit test runs, but you could
reproduce this failure with a trivial main() that calls flockfile
or ftrylockfile on one of the standard streams before otherwise
using stdio.

168667c972 Add non-macro stdin/stdout/stderr too.
Various C and C++ standards explicitly say that stdin/stdout/stderr
should be macros, but glibc makes them global variables too. This
means it's possible to write code that uses those names as locals,
but that code (toybox being an example) won't build on bionic.

If we'd done this earlier, we could have hidden __sF for LP64, but
it's too late now.

The LP64 has a duplicate copy of part of stdio, and relies
on bionic supplying this part. We should remove the hack from
the NDK, at least for LP64, and then revert this.

I cleaned up most of our warnings last week but forgot to turn on -Werror,
so of course we're getting new warnings already. I've left -Werror commented
out in those places where we still have warnings to deal with before we can
turn on -Werror.

everything. (Yes, I found this bug the hard way.)

edd7c2ec25 Fix the printf issue for 64 bits. The following case:
printf("%1$s %1$s\n", "test");

would print garbage instead of the second "test". The problem is __find_arguments
and the patch is a backport of two patches from OpenBSD that fix the issue:

Author: tedu <tedu@cvs.openbsd.org>
Date:   Sat Apr 29 23:00:24 2006 +0000

    check mmap for failure.  the helper functions using it return -1, but
    callers do not yet check since printf() for example is not documented
    to return an error.
    some formatting cleanups.
    mostly ok deraadt millert

Author: millert <millert@cvs.openbsd.org>
Date:   Fri May 16 14:28:54 2008 +0000

    C99 says that for each va_copy() there must be a matching va_end().
    Replace the non-portable hackery in __find_arguments() with a union.
    From FreeBSD.

eb847bc866 Fix x86_64 build, clean up intermediate libraries.
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.
