@@ -73,6 +73,13 @@ Differences between current and Android 2.2:
- <dlfcn.h>: fixed dlopen() implementation to support dlopen(NULL, ...).
This allows one to look at the dynamic symbols exported by an executable.
- <private/bionic_tls.h>: use kernel helper functions for static versions
of the C library. This is necessary because we don't know where the corresponding
machine code is going to run, and the optimization for __get_tls() might
not match the features of the target device where we run a static executable
linked to the C library. This fixes one of the bug that explains why gdbserver
didn't work well with threads.
