Don't export new/delete from libc shared libraries. This used to be handled by -fvisibility=hidden on libc_cxa, but that was broken by the resolution of https://llvm.org/PR22419 (introduced to Android in today's clang update). Now we just use a version script that prevents these from being re-exported from our shared libraries. Change-Id: Ib290e1d0d7426e09ad17a91178162fff6dbdcfa9 2015-04-02 01:26:54 +02:00			`LIBC {`
Fix volantis boot. NVIDIA binary blobs are assuming that __cache_clear, _Unwind_Backtrace, and _Unwind_GetIP are all in some library that they link, but now we've cleaned up this leakage, they're no longer getting it. Deliberately leak the symbols from libc.so until we get new blobs. Bug: http://b/20065774 Change-Id: I92ef07b2bce8d1ad719bf40dab41d745cd6904d4 2015-04-03 20:27:53 +02:00			`global:`
