Fix x86 __memset_chk.
When __memset_chk_fail moved to C++, we didn't take into account
that the stack wasn't set up correctly for the jump from assembler.
Presumably no one had run the 32-bit x86 tests until now!

Fix x86 __memset_chk.
The stack offsets assumed we'd pushed %ebx. Unlike x86-64 we can't fall
through, but we can avoid repeating work we've already done.

David 'Digit' Turner <digit@google.com> |
libc: Fix 'index' symbol export.
The C library didn't export the 'index' symbol, but its C++ name-mangling
instead, which broke the ABI and prevented some applications from loading
properly.
The main reason was that the implementation under bionic/index.cpp relied
on the declaration to specify that the function has C linkage.
However, the declaration for index() was removed from both <string.h>
and <strings.h> in a recent patch, which made the compiler think it was
ok to compile the function with C++ linkage instead!
This patch does the following:
- Move index() definition to bionic/ndk_cruft.cpp and ensure it uses
C linkage.
Note that this removes index() from the 64-bit library entirely, this
is intentional and will break source compatibility. Simply replacing
an index() call with the equivalent strchr() should be enough to fix
this in third-party code.
- Remove bionic/index.cpp from the tree and build files.
- Remove x86 assembly implementation from arch-x86/ to avoid conflict
with the one in ndk_cruft.cpp

Add 32-bit Silvermont-optimized string/memory functions.
Add following functions:
bcopy, memcpy, memmove, memset, bzero, memcmp, wmemcmp, strlen,
strcpy, strncpy, stpcpy, stpncpy.
Create new directories inside arch-x86 to specify architecture: atom,
silvermont and generic (non atom or silvermont architectures are treated like generic).
Due to introducing optimized versions of stpcpy and stpncpy,
c-implementations of these functions are moved from
common for architectures makefile to arm and mips specific makefiles.
