David 'Digit' Turner 5fbf2e0992 libc: Define new symbol visibility macros ... This patch defines a few new macros that can be used to control the visibility of symbols exported by the C library: - ENTRY_PRIVATE() can be used in assembly sources to indicate that an assembler function should have "hidden" visibility, i.e. will never be exported by the C library's shared library. This is the equivalent of using __LIBC_HIDDEN__ for a C function, but ENTRY_PRIVATE() works like ENTRY(), and must be used with END() to tag the end of the function. - __LIBC_ABI_PUBLIC__ can be used to tag a C functions as being part of the C library's public ABI. This is important for a few functions that must be exposed by the NDK to maintain binary compatibility. Once a symbol has been tagged with this macro, it shall *never* be removed from the library, even if it becomes directly unused due to implementation changes (e.g. __is_threaded). - __LIBC_ABI_PRIVATE__ can be used for C functions that should always be exported by the C library because they are used by other libraries in the platform, but should not be exposed by the NDK. It is possible to remove such symbols from the implementation if all callers are also modified. + Add missing END() assembly macro for x86 Change-Id: Ia96236ea0dbec41d57bea634b39d246b30e5e234		2012-01-31 22:19:09 +01:00
