/* This file contains dummy references to libgcc.a functions to force the
* dynamic linker to copy their definition into the final libc.so binary.
*
* They are required to ensure backwards binary compatibility with
* Android 1.5 and Android 1.6 system images. Some applications built
* using the NDK require them to be here.
*
* Now, for a more elaborate description of the issue:
*
* libgcc.a is a compiler-specific library containing various helper
* functions used to implement certain operations that are not necessarily
* supported by the target CPU. For example, integer division doesn't have a
* corresponding CPU instruction on ARMv5, and is instead implemented in the
* compiler-generated machine code as a call to an __idiv helper function.
*
* Normally, one has to place libgcc.a in the link command used to generate
* target binaries (shared libraries and executables) after all objects and
* static libraries, but before dependent shared libraries, i.e. something
* like:
* gcc <options> -o libfoo.so foo.a libgcc.a -lc -lm
*
* This ensures that any helper function needed by the code in foo.a is copied
* into the final libfoo.so. Unfortunately, the Android build system has been
* using this instead:
*
* gcc <options> -o libfoo.so foo.a -lc -lm libgcc.a
*
* The problem with this is that if one helper function needed by foo.a has
* already been copied into libc.so or libm.so, then nothing will be copied
* into libfoo.so. Instead, a symbol import definition will be added to it
* so libfoo.so can directly call the one in libc.so at runtime.
*
* When changing toolchains for 2.0, the set of helper functions copied to
* libc.so changed, which resulted in some native shared libraries generated
* with the NDK to fail to load properly.
*
* The NDK has been fixed after 1.6_r1 to use the correct link command, so
* any native shared library generated with it should now be safe from that
* problem. On the other hand, existing shared libraries distributed with
* applications that were generated with a previous version of the NDK
* still need all 1.5/1.6 helper functions in libc.so and libn.so
*
* Final note: some of the functions below should really be in libm.so to
* completely reflect the state of 1.5/1.6 system images. However,
* since libm.so depends on libc.so, it's easier to put all of
* these in libc.so instead, since the dynamic linker will always
* search in libc.so before libm.so for dependencies.

@ -63,6 +63,18 @@ time_t:
Instead, Bionic provides a <time64.h> header that defines a time64_t type,
and related functions like mktime64(), localtime64(), etc...
strftime() uses time64_t internally, so the '%s' format (seconds since the
epoch) is supported for dates >= 2038.
strftime_tz():
Bionic also provides the non-standard strftime_tz() function, a variant
of strftime() which also accepts a time locale descriptor as defined
by "struct strftime_locale" in <time.h>.
This function is used by the low-level framework code in Android.
